+Configuration file
+==================
+
+Pretix reads its configuration from a configuration file. It tries to find this file
+at the following locations. It will try to read the file from the specified paths in
+the following order. The file that is found *last* will override the settings from
+the files found before.
+
+1. ``PRETIX_CONFIG_FILE`` environment variable
+2. ``/etc/pretix/pretix.cfg``
+3. ``~/.pretix.cfg``
+4. ``pretix.cfg`` in the current working directory
+
+The file is expected to be in the INI format as specified in the `Python documentation`_.
+
+The config file may contain the following sections (all settings are optional and have
+default values). We suggest that you start from the examples given in one of the
+installation tutorials.
+
+.. note::
+
+    The configuration file is the recommended way to configure pretix. However, you can
+    also set them through environment variables. In this case, the syntax is
+    ``PRETIX_SECTION_CONFIG``. For example, to configure the setting ``password_reset``
+    from the ``[pretix]`` section, set ``PRETIX_PRETIX_PASSWORD_RESET=off`` in your
+    environment.
+
+pretix settings
+---------------
+
+Example::
+
+    [pretix]
+    instance_name=pretix.de
+    url=http://localhost
+    currency=EUR
+    datadir=/data
+    plugins_default=pretix.plugins.sendmail,pretix.plugins.statistics
+
+``instance_name``
+    The name of this installation. Default: ``pretix.de``
+
+``url``
+    The installation's full URL, without a trailing slash.
+
+``currency``
+    The default currency as a three-letter code. Defaults to ``EUR``.
+
+``cachedir``
+    The local path to a directory where temporary files will be stored.
+    Defaults to the ``cache`` directory below the ``datadir``.
+
+``datadir``
+    The local path to a data directory that will be used for storing user uploads and similar
+    data. Defaults to the value of the environment variable ``DATA_DIR`` or ``data``.
+
+``logdir``
+    The local path to a directory where log files will be stored.
+    Defaults to the ``logs`` directory below the ``datadir``.
+
+``plugins_default``

+    Can be ``True`` to make two-factor authentication obligatory for all users or ``staff`` to make it only
+    obligatory to users with admin permissions. Defaults to ``False``.
+
+``trust_x_forwarded_for``
+    Specifies whether the ``X-Forwarded-For`` header can be trusted. Only set to ``on`` if you have a reverse
+    proxy that actively removes and re-adds the header to make sure the correct client IP is the first value.
+    Defaults to ``off``.
+
+``trust_x_forwarded_proto``

+    proxy that actively removes and re-adds the header to make sure the correct value is set.
+    Defaults to ``off``.
+
+``csp_log``
+    Log violations of the Content Security Policy (CSP). Defaults to ``on``.
+
+``csp_additional_header``
+    Specifies a CSP header that will be **merged** with pretix's default header. For example, if you set this
+    to ``script-src https://mycdn.com``, pretix will add ``https://mycdn.com`` as an **additional** allowed source
+    to all CSP headers. Empty by default.
+
+``loglevel``
+    Set console and file log level (``DEBUG``, ``INFO``, ``WARNING``, ``ERROR`` or ``CRITICAL``). Defaults to ``INFO``.
+
+``request_id_header``
+    Specifies the name of a header that should be used for logging request IDs. Off by default.
+
+Locale settings
+---------------
+
+Example::
+
+    [locale]
+    default=de
+    timezone=Europe/Berlin
+
+``default``
+    The system's default locale. Default: ``en``
+
+``timezone``
+    The system's default timezone as a ``pytz`` name. Default: ``UTC``
+
+Database settings
+-----------------
+
+Example::
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    password=abcd
+    host=localhost
+    port=3306
+    advisory_lock_index=1
+    disable_server_side_cursors=0
+    sslmode=require
+    sslrootcert=/etc/pretix/postgresql-ca.crt
+    sslcert=/etc/pretix/postgresql-client-crt.crt
+    sslkey=/etc/pretix/postgresql-client-key.key
+
+``backend``
+    One of ``sqlite3`` and ``postgresql``.
+    Default: ``sqlite3``.
+
+``name``
+    The database's name. Default: ``db.sqlite3``.
+
+``user``, ``password``, ``host``, ``port``
+    Connection details for the database connection. Empty by default.
+
+``advisory_lock_index``
+    On PostgreSQL, pretix uses the "advisory lock" feature. However, advisory locks use a server-wide name space and
+    and are not scoped to a specific database. If you run multiple pretix applications with the same PostgreSQL server,
+    you should set separate values for this setting (integers up to 256).
+
+``disable_server_side_cursors``
+    On PostgreSQL pretix might use server side cursors for certain operations. This is generally fine but will break in
+    specific circumstances, for example when connecting to PostgreSQL through a PGBouncer configured with a transaction
+    pool mode. Off by default (i.e. by default server side cursors will be used).
+
+``sslmode``, ``sslrootcert``
+    Connection TLS details for the PostgreSQL database connection. Possible values of ``sslmode`` are ``disable``, ``allow``, ``prefer``, ``require``, ``verify-ca``, and ``verify-full``. ``sslrootcert`` should be the accessible path of the ca certificate. Both values are empty by default.
+
+``sslcert``, ``sslkey``
+    Connection mTLS details for the PostgreSQL database connection. It's also necessary to specify ``sslmode`` and ``sslrootcert`` parameters, please check the correct values from the TLS part. ``sslcert`` should be the accessible path of the client certificate.  ``sslkey`` should be the accessible path of the client key. All values are empty by default.
+
+.. _`config-replica`:
+
+Database replica settings
+-------------------------
+
+If you use a replicated database setup, pretix expects that the default database connection always points to the primary database node.
+Routing read queries to a replica on database layer is **strongly** discouraged since this can lead to inaccurate such as more tickets
+being sold than are actually available.
+
+However, pretix can still make use of a database replica to keep some expensive queries with that can tolerate some latency from your
+primary database, such as backend search queries. The ``replica`` configuration section can have the same settings as the ``database``
+section (except for the ``backend`` setting) and will default back to the ``database`` settings for all values that are not given. This
+way, you just need to specify the settings that are different for the replica.
+
+Example::
+
+    [replica]
+    host=192.168.0.2
+
+.. _`config-urls`:
+
+URLs
+----
+
+Example::
+
+    [urls]
+    media=/media/
+    static=/static/
+
+``media``
+    The URL to be used to serve user-uploaded content. You should not need to modify
+    this. Default: ``/media/``
+
+``static``
+    The URL to be used to serve static files. You should not need to modify
+    this. Default: ``/static/``
+
+.. _`mail-settings`:
+
+Email
+-----
+
+Example::
+
+    [mail]
+    from=hello@localhost
+    host=127.0.0.71
+    user=pretix
+    password=foobar
+    port=1025
+    tls=on
+    ssl=off
+
+``host``, ``port``
+    The SMTP Host to connect to. Defaults to ``localhost`` and ``25``.
+
+``user``, ``password``
+    The SMTP user data to use for the connection. Empty by default.
+
+``tls``, ``ssl``
+    Use STARTTLS or SSL for the SMTP connection. Off by default.
+
+``from``
+    The email address to set as ``From`` header in outgoing emails by the system.
+    Default: ``pretix@localhost``
+
+``from_notifications``
+    The email address to set as ``From`` header in admin notification emails by the system.
+    Defaults to the value of ``from``.
+
+``from_organizers``
+    The email address to set as ``From`` header in outgoing emails by the system sent on behalf of organizers.
+    Defaults to the value of ``from``.
+
+``custom_sender_verification_required``
+    If this is on (the default), organizers need to verify email addresses they want to use as senders in their event.
+
+``custom_sender_spf_string``
+    If this is set to a valid SPF string, pretix will show a warning if organizers use a sender address from a domain
+    that does not include this value.
+
+``custom_smtp_allow_private_networks``
+    If this is off (the default), custom SMTP servers cannot be private network addresses.
+
+``admins``
+    Comma-separated list of email addresses that should receive a report about every error code 500 thrown by pretix.
+
+.. _`django-settings`:
+
+Django settings
+---------------
+
+Example::
+
+    [django]
+    secret=j1kjps5a5&4ilpn912s7a1!e2h!duz^i3&idu@_907s$wrz@x-
+    debug=off
+
+``secret``
+    The secret to be used by Django for signing and verification purposes. If this
+    setting is not provided, pretix will generate a random secret on the first start
+    and will store it in the filesystem for later usage.
+
+``secret_fallback0`` ... ``secret_fallback9``
+    Prior versions of the secret to be used by Django for signing and verification purposes that will still
+    be accepted but no longer be used for new signing.
+
+``debug``
+    Whether or not to run in debug mode. Default is ``False``.
+
+    .. WARNING:: Never set this to ``True`` in production!
+
+``profile``
+    Enable code profiling for a random subset of requests. Disabled by default, see
+    :ref:`perf-monitoring` for details.
+
+.. _`metrics-settings`:
+
+Metrics
+-------
+
+If you want to fetch internally collected prometheus-style metrics you need to configure the credentials for the
+metrics endpoint and enable it::
+
+    [metrics]
+    enabled=true
+    user=your_user
+    passphrase=mysupersecretpassphrase
+
+Currently, metrics-collection requires a redis server to be available.
+
+
+Memcached
+---------
+
+You can use an existing memcached server as pretix's caching backend::
+
+    [memcached]
+    location=127.0.0.1:11211
+
+``location``
+    The location of memcached, either a host:port combination or a socket file.
+
+If no memcached is configured, pretix will use redis for caching. If neither is configured, pretix will not use any caching.
+
+.. note:: If you use memcached and you deploy pretix across multiple servers, you should use *one*
+          shared memcached instance, not multiple ones, because cache invalidations would not be
+          propagated otherwise.
+
+Redis
+-----
+
+If a redis server is configured, pretix can use it for locking, caching and session storage
+to speed up various operations::
+
+    [redis]
+    location=redis://127.0.0.1:6379/1
+    sessions=false
+    sentinels=[
+            ["sentinel_host_1", 26379],
+            ["sentinel_host_2", 26379],
+            ["sentinel_host_3", 26379]
+        ]
+    password=password
+    ssl_cert_reqs=required
+    ssl_ca_certs=/etc/pretix/redis-ca.pem
+    ssl_keyfile=/etc/pretix/redis-client-crt.pem
+    ssl_certfile=/etc/pretix/redis-client-key.key
+
+``location``
+    The location of redis, as a URL of the form ``redis://[:password]@localhost:6379/0``
+    or ``unix://[:password]@/path/to/socket.sock?db=0``
+
+``sessions``
+    When this is set to ``True``, redis will be used as the session storage.
+
+``sentinels``
+    Configures redis sentinels to use.
+    If you don't want to use redis sentinels, you should omit this option.
+    If this is set, redis via sentinels will be used instead of plain redis.
+    In this case the location should be of the form ``redis://my_master/0``.
+    The ``sentinels`` variable should be a json serialized list of sentinels,
+    each being a list with the two elements hostname and port.
+    You cannot provide a password within the location when using sentinels.
+    Note that the configuration format requires you to either place the entire
+    value on one line or make sure all values are indented by at least one space.
+
+``password``
+    If your redis setup doesn't require a password or you already specified it in the location you can omit this option.
+    If this is set it will be passed to redis as the connection option PASSWORD.
+
+``ssl_cert_reqs``
+    If this is set it will be passed to redis as the connection option ``SSL_CERT_REQS``.
+    Possible values are ``none``, ``optional``, and ``required``.
+
+``ssl_ca_certs``
+    If your redis setup doesn't require TLS you can omit this option.
+    If this is set it will be passed to redis as the connection option ``SSL_CA_CERTS``. Possible value is the ca path.
+
+``ssl_keyfile``
+    If your redis setup doesn't require mTLS you can omit this option.
+    If this is set it will be passed to redis as the connection option ``SSL_KEYFILE``. Possible value is the keyfile path.
+
+``ssl_certfile``
+    If your redis setup doesn't require mTLS you can omit this option.
+    If this is set it will be passed to redis as the connection option ``SSL_CERTFILE``. Possible value is the certfile path.
+
+If redis is not configured, pretix will store sessions and locks in the database. If memcached
+is configured, memcached will be used for caching instead of redis.
+
+Translations
+------------
+
+pretix comes with a number of translations. All languages are enabled by default. If you want to limit
+the languages available in your installation, you can enable a set of languages like this::
+
+    [languages]
+    enabled=en,de
+
+Some of the languages them are marked as "incubating", which means
+they can usually only be selected in development mode. If you want to use them nevertheless, you
+can activate them like this::
+
+    [languages]
+    allow_incubating=pt-br,da
+
+You can also tell pretix about additional paths where it will search for translations::
+
+    [languages]
+    path=/path/to/my/translations
+
+For a given language (e.g. ``pt-br``), pretix will then look in the
+specific sub-folder, e.g. ``/path/to/my/translations/pt_BR/LC_MESSAGES/django.po``.
+
+Celery task queue
+-----------------
+
+For processing long-running tasks asynchronously, pretix requires the celery task queue.
+For communication between the web server and the task workers in both direction, a messaging
+queue and a result backend is needed. You can use a redis database for both directions, or
+an AMQP server (e.g. RabbitMQ) as a broker and redis or your database as a result backend::
+
+    [celery]
+    broker=amqp://guest:guest@localhost:5672//
+    backend=redis://localhost/0
+    broker_transport_options="{}"
+    backend_transport_options="{}"
+
+RabbitMQ might be the better choice if you have a complex, multi-server, high-performance setup,
+but as you already should have a redis instance ready for session and lock storage, we recommend
+redis for convenience. See the `Celery documentation`_ for more details.
+
+The two ``transport_options`` entries can be omitted in most cases.
+If they are present they need to be a valid JSON dictionary.
+For possible entries in that dictionary see the `Celery documentation`_.
+
+It is possible the use Redis with TLS/mTLS for the broker or the backend. To do so, it is necessary to specify the TLS identifier ``rediss``, the ssl mode ``ssl_cert_reqs`` and optionally specify the CA (TLS) ``ssl_ca_certs``, cert ``ssl_certfile`` and key ``ssl_keyfile`` (mTLS) path as encoded string. the following uri describes the format and possible parameters ``rediss://0.0.0.0:6379/1?ssl_cert_reqs=required&ssl_ca_certs=%2Fetc%2Fpretix%2Fredis-ca.pem&ssl_certfile=%2Fetc%2Fpretix%2Fredis-client-crt.pem&ssl_keyfile=%2Fetc%2Fpretix%2Fredis-client-key.key``
+
+To use redis with sentinels set the broker or backend to ``sentinel://sentinel_host_1:26379;sentinel_host_2:26379/0``
+and the respective transport_options to ``{"master_name":"mymaster"}``.
+If your redis instances behind the sentinel have a password use ``sentinel://:my_password@sentinel_host_1:26379;sentinel_host_2:26379/0``.
+If your redis sentinels themselves have a password set the transport_options to ``{"master_name":"mymaster","sentinel_kwargs":{"password":"my_password"}}``.
+
+Sentry
+------
+
+pretix has native support for sentry, a tool that you can use to track errors in the
+application. If you want to use sentry, you need to set a DSN in the configuration file::
+
+    [sentry]
+    dsn=https://<key>:<secret>@sentry.io/<project>
+    traces_sample_rate=0.5
+    traces_sample_token=xyz
+
+``dsn``
+    You will be given this value by your sentry installation.
+
+``traces_sample_rate``
+    Sample rate for performance monitoring.
+
+``traces_sample_token``
+    If this token is found in a query string, a trace will always be sampled.
+
+
+Caching
+-------
+
+You can adjust some caching settings to control how much storage pretix uses::
+
+    [cache]
+    tickets=48  ; Number of hours tickets (PDF, passbook, …) are cached
+
+
+Secret length
+-------------
+
+If you are really paranoid, you can increase the length of random strings pretix uses in
+various places like order codes, secrets in the ticket QR codes, etc. Example::
+
+    [entropy]
+    ; Order code needs to be < 16 characters, default is 5
+    order_code=5
+    ; Ticket secret needs to be < 64 characters, default is 32
+    ticket_secret=32
+    ; Voucher code needs to be < 255 characters, default is 16
+    voucher_code=16
+
+External tools
+--------------
+
+pretix can make use of some external tools if they are installed. Currently, they are all optional. Example::
+
+    [tools]
+    pdftk=/usr/bin/pdftk
+
+.. _Python documentation: https://docs.python.org/3/library/configparser.html?highlight=configparser#supported-ini-file-structure
+.. _Celery documentation: http://docs.celeryproject.org/en/latest/userguide/configuration.html
+
+Maximum upload file sizes
+-------------------------
+
+You can configure the maximum file size for uploading various files::
+
+    [pretix_file_upload]
+    ; Max upload size for images in MiB, defaults to 10 MiB
+    max_size_image = 12
+    ; Max upload size for favicons in MiB, defaults to 1 MiB
+    max_size_favicon = 2
+    ; Max upload size for email attachments of manually sent emails in MiB, defaults to 10 MiB
+    max_size_email_attachment = 15
+    ; Max upload size for email attachments of automatically sent emails in MiB, defaults to 1 MiB
+    max_size_email_auto_attachment = 2
+    ; Max upload size for other files in MiB, defaults to 10 MiB
+    ; This includes all file upload type order questions
+    max_size_other = 100
+
+
+GeoIP
+-----
+
+pretix can optionally make use of a GeoIP database for some features. It needs a file in ``mmdb`` format, for example
+`GeoLite2`_ or `GeoAcumen`_::
+
+    [geoip]
+    path=/var/geoipdata/
+    filename_country=GeoLite2-Country.mmdb
+

+Dealing with errors
+===================
+
+If you encounter an error in pretix, please follow the following steps to debug it:
+
+* If the error message is shown on a **white page** and the last line of the error includes "nginx", the error is not with pretix
+  directly but with your nginx webserver. This might mean that pretix is not running, but it could also be something else.
+  Please first check your nginx error log. The default location is ``/var/log/nginx/error.log``.
+
+  * If it turns out pretix is not running, check the output of ``docker logs pretix`` for a docker installation and
+    ``journalctl -u pretix-web.service`` for a manual installation.
+
+* If the error message is an "**Internal Server Error**" in purple pretix design, please check pretix' log file which by default is at
+  ``/var/pretix-data/logs/pretix.log`` if you installed with docker and ``/var/pretix/data/logs/pretix.log`` otherwise. If you don't
+  know how to interpret it, open a discussion on GitHub with the relevant parts of the log file.
+
+  * If the error message includes ``/usr/bin/env: ‘node’: No such file or directory``, you forgot to install ``node.js``
+
+  * If the error message includes ``OfflineGenerationError``, you might have forgot to run the ``rebuild`` step after a pretix update
+    or plugin installation.
+
+  * If the error message mentions your database server or redis server, make sure these are running and accessible.
+
+* If pretix loads fine but certain actions (creating carts, orders, or exports, downloading tickets, sending emails) **take forever**,
+  ``pretix-worker`` is not running. Check the output of ``docker logs pretix`` for a docker installation and
+  ``journalctl -u pretix-worker.service`` for a manual installation.
+
+* If the page loads but all **styles are missing**, you probably forgot to update your nginx configuration file after an upgrade of your
+  operating system's python version.
+
+
+If you are unable to debug the issue any further, please open a **discussion** on GitHub in our `Q&A Forum`_. Do **not** open an issue
+right away, since most things turn out not to be a bug in pretix but a mistake in your server configuration. Make sure to include
+relevant log excerpts in your question.
+
+If you're a pretix Enterprise customer, you can also reach out to support@pretix.eu with your issue right away.

+Additional database indices
+===========================
+
+If you have a large pretix database, some features such as search for orders or events might turn pretty slow.
+For PostgreSQL, we have compiled a list of additional database indexes that you can add to speed things up.
+Just like any index, they in turn make write operations insignificantly slower and cause the database to use
+more disk space.
+
+The indexes aren't automatically created by pretix since Django does not allow us to do so only on PostgreSQL
+(and they won't work on other databases). Also, they're really not necessary if you're not having tens of
+thousands of records in your database.
+
+However, this also means they won't automatically adapt if some of the referred fields change in future updates of pretix
+and you might need to re-check this page and change them manually.
+
+Here is the currently recommended set of commands::
+
+    CREATE EXTENSION pg_trgm;
+
+    CREATE INDEX CONCURRENTLY pretix_addidx_event_slug
+        ON pretixbase_event
+        USING gin (upper("slug") gin_trgm_ops);

+
+Installing a development version
+================================
+
+If you want to use a feature of pretix that is not yet contained in the last monthly release, you can also
+install a development version with pretix.
+
+.. warning:: When in production, we strongly recommend only installing released versions. Development versions might
+             be broken, incompatible to plugins, or in rare cases incompatible to upgrade later on.
+
+
+Manual installation
+-------------------
+
+You can use ``pip`` to update pretix directly to the development branch. Then, upgrade as usual::
+
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install -U "git+https://github.com/pretix/pretix.git#egg=pretix"
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+    (venv)$ python -m pretix updateassets
+    # systemctl restart pretix-web pretix-worker
+
+Docker installation
+-------------------
+
+To use the latest development version with Docker, first pull it from Docker Hub::
+
+    $ docker pull pretix/standalone:latest
+
+
+Then change your ``/etc/systemd/system/pretix.service`` file to use the ``:latest`` tag instead of ``:stable`` as well
+and upgrade as usual::
+
+    $ systemctl restart pretix.service
+    $ docker exec -it pretix.service pretix upgrade

+
+Small-scale deployment with Docker
+==================================
+
+This guide describes the installation of a small-scale installation of pretix using docker. By small-scale, we mean
+that everything is being run on one host and you don't expect thousands of participants trying to get a ticket within
+a few minutes. In this setup, as many parts of pretix as possible are hidden away in one single docker container.
+This has some trade-offs in terms of performance and isolation but allows a rather easy installation.
+
+.. warning:: Even though we try to make it straightforward to run pretix, it still requires some Linux experience to
+             get it right. If you're not feeling comfortable managing a Linux server, check out our hosting and service
+             offers at `pretix.eu`_.
+
+We tested this guide on the Linux distribution **Debian 11.0** but it should work very similar on other
+modern distributions, especially on all systemd-based ones.
+
+Requirements
+------------
+
+Please set up the following systems beforehand, we'll not explain them here (but see these links for external
+installation guides):
+
+* `Docker`_
+* A SMTP server to send out mails, e.g. `Postfix`_ on your machine or some third-party server you have credentials for
+* A HTTP reverse proxy, e.g. `nginx`_ or Apache to allow HTTPS connections
+* A `PostgreSQL`_ 12+ database server
+* A `redis`_ server
+
+We also recommend that you use a firewall, although this is not a pretix-specific recommendation. If you're new to
+Linux and firewalls, we recommend that you start with `ufw`_.
+
+.. note:: Please, do not run pretix without HTTPS encryption. You'll handle user data and thanks to `Let's Encrypt`_
+          SSL certificates can be obtained for free these days. We also *do not* provide support for HTTP-only
+          installations except for evaluation purposes.
+
+.. warning:: By default, using `ufw` in conjunction will not have any effect. Please make sure to either bind the exposed
+             ports of your docker container explicitly to 127.0.0.1 or configure docker to respect any set up firewall
+             rules.
+
+On this guide
+-------------
+
+All code lines prepended with a ``#`` symbol are commands that you need to execute on your server as ``root`` user;
+all lines prepended with a ``$`` symbol can also be run by an unprivileged user.
+
+Data files
+----------
+
+First of all, you need to create a directory on your server that pretix can use to store data files and make that
+directory writable to the user that runs pretix inside the docker container::
+
+    # mkdir /var/pretix-data
+    # chown -R 15371:15371 /var/pretix-data
+
+Database
+--------
+
+Next, we need a database and a database user. We can create these with any kind of database managing tool or directly on
+our database's shell. Please make sure that UTF8 is used as encoding for the best compatibility. You can check this with
+the following command::
+
+    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
+
+For PostgreSQL database creation, we would do::
+
+    # sudo -u postgres createuser -P pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+Make sure that your database listens on the network. If PostgreSQL on the same same host as docker, but not inside a docker container, we recommend that you just listen on the Docker interface by changing the following line in ``/etc/postgresql/<version>/main/postgresql.conf``::
+
+    listen_addresses = 'localhost,172.17.0.1'
+
+You also need to add a new line to ``/etc/postgresql/<version>/main/pg_hba.conf`` to allow network connections to this user and database::
+
+    host    pretix          pretix          172.17.0.1/16           md5
+
+Restart PostgreSQL after you changed these files::
+
+    # systemctl restart postgresql
+
+If you have a firewall running, you should also make sure that port 5432 is reachable from the ``172.17.0.1/16`` subnet.
+
+Redis
+-----
+
+For caching and messaging in small-scale setups, pretix recommends using redis. In this small-scale setup we assume a
+redis instance to be running on the same host. To avoid the hassle with network configurations and firewalls, we
+recommend connecting to redis via a unix socket. To enable redis on unix sockets, add the following to your
+``/etc/redis/redis.conf``::
+
+    unixsocket /var/run/redis/redis.sock
+    unixsocketperm 777
+
+Now restart redis-server::
+
+    # systemctl restart redis-server
+
+In this setup, systemd will delete ``/var/run/redis`` on every redis restart, which will cause issues with pretix. To
+prevent this, you can execute::
+
+   # systemctl edit redis-server
+
+And insert the following::
+
+    [Service]
+    # Keep the directory around so that pretix.service in docker does not need to be
+    # restarted when redis is restarted.
+    RuntimeDirectoryPreserve=yes
+
+.. warning:: Setting the socket permissions to 777 is a possible security problem. If you have untrusted users on your
+             system or have high security requirements, please don't do this and let redis listen to a TCP socket
+             instead. We recommend the socket approach because the TCP socket in combination with docker's networking
+             can easily become an even worse security hole when configured slightly wrong. Read more about security
+             on the `redis website`_.
+
+             Another possible solution is to run `redis in docker`_ and link the containers using docker's networking
+             features.
+
+Config file
+-----------
+
+We now create a config directory and config file for pretix::
+
+    # mkdir /etc/pretix
+    # touch /etc/pretix/pretix.cfg
+    # chown -R 15371:15371 /etc/pretix/
+    # chmod 0700 /etc/pretix/pretix.cfg
+
+Fill the configuration file ``/etc/pretix/pretix.cfg`` with the following content (adjusted to your environment)::
+
+    [pretix]
+    instance_name=My pretix installation
+    url=https://pretix.mydomain.com
+    currency=EUR
+    ; DO NOT change the following value, it has to be set to the location of the
+    ; directory *inside* the docker container
+    datadir=/data
+    trust_x_forwarded_for=on
+    trust_x_forwarded_proto=on
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    ; Replace with the password you chose above
+    password=*********
+    ; In most docker setups, 172.17.0.1 is the address of the docker host. Adjust
+    ; this to wherever your database is running, e.g. the name of a linked container.
+    host=172.17.0.1
+
+    [mail]
+    ; See config file documentation for more options
+    from=tickets@yourdomain.com
+    ; This is the default IP address of your docker host in docker's virtual
+    ; network. Make sure postfix listens on this address.
+    host=172.17.0.1
+
+    [redis]
+    location=unix:///var/run/redis/redis.sock?db=0
+    ; Remove the following line if you are unsure about your redis' security
+    ; to reduce impact if redis gets compromised.
+    sessions=true
+
+    [celery]
+    backend=redis+socket:///var/run/redis/redis.sock?virtual_host=1
+    broker=redis+socket:///var/run/redis/redis.sock?virtual_host=2
+
+See :ref:`email configuration <mail-settings>` to learn more about configuring mail features.
+
+Docker image and service
+------------------------
+
+First of all, download the latest stable pretix image by running::
+
+    $ docker pull pretix/standalone:stable
+
+We recommend starting the docker container using systemd to make sure it runs correctly after a reboot. Create a file
+named ``/etc/systemd/system/pretix.service`` with the following content::
+
+    [Unit]
+    Description=pretix
+    After=docker.service
+    Requires=docker.service
+
+    [Service]
+    TimeoutStartSec=0
+    ExecStartPre=-/usr/bin/docker kill %n
+    ExecStartPre=-/usr/bin/docker rm %n
+    ExecStart=/usr/bin/docker run --name %n -p 127.0.0.1:8345:80 \
+        -v /var/pretix-data:/data \
+        -v /etc/pretix:/etc/pretix \
+        -v /var/run/redis:/var/run/redis \
+        --sysctl net.core.somaxconn=4096 \
+        pretix/standalone:stable all
+    ExecStop=/usr/bin/docker stop %n
+
+    [Install]
+    WantedBy=multi-user.target
+
+You can now run the following commands
+to enable and start the service::
+
+    # systemctl daemon-reload
+    # systemctl enable pretix
+    # systemctl start pretix
+
+Cronjob
+-------
+
+You need to set up a cronjob that runs the management command ``runperiodic``. The exact interval is not important
+but should be something between every minute and every hour. You could for example configure cron like this::
+
+    15,45 * * * * /usr/bin/docker exec pretix.service pretix cron
+
+The cronjob may run as any user that can use the docker daemon.
+
+SSL
+---
+
+The following snippet is an example on how to configure a nginx proxy for pretix::
+
+    server {
+        listen 80 default_server;
+        listen [::]:80 ipv6only=on default_server;
+        server_name pretix.mydomain.com;
+        location / {
+            return 301 https://$host$request_uri;
+        }
+    }
+    server {
+        listen 443 default_server;
+        listen [::]:443 ipv6only=on default_server;
+        server_name pretix.mydomain.com;
+
+        ssl on;
+        ssl_certificate /path/to/cert.chain.pem;
+        ssl_certificate_key /path/to/key.pem;
+
+        location / {
+            proxy_pass http://localhost:8345;
+            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+            proxy_set_header X-Forwarded-Proto https;
+            proxy_set_header Host $http_host;
+        }
+    }
+
+
+We recommend reading about setting `strong encryption settings`_ for your web server.
+
+Next steps
+----------
+
+Yay, you are done! You should now be able to reach pretix at https://pretix.yourdomain.com/control/ and log in as
+*admin@localhost* with a password of *admin*. Don't forget to change that password! Create an organizer first, then
+create an event and start selling tickets!
+
+You should probably read :ref:`maintainance` next.
+
+.. _`docker_updates`:
+
+Updates
+-------
+
+.. warning:: While we try hard not to break things, **please perform a backup before every upgrade**.
+
+Updates are fairly simple, but require at least a short downtime::
+
+    # docker pull pretix/standalone:stable
+    # systemctl restart pretix.service
+    # docker exec -it pretix.service pretix upgrade
+
+Restarting the service can take a few seconds, especially if the update requires changes to the database.
+Replace ``stable`` above with a specific version number like ``1.0`` or with ``latest`` for the development
+version, if you want to.
+
+Make sure to also read :ref:`update_notes` and the release notes of the version you are updating to. Pay special
+attention to the "Runtime and server environment" section of all release notes between your current and new version.
+
+.. _`docker_plugininstall`:
+
+Install a plugin
+----------------
+
+To install a plugin, you need to build your own docker image. To do so, create a new directory and place a file
+named ``Dockerfile`` in it. The Dockerfile could look like this (replace ``pretix-passbook`` with the plugins of your
+choice)::
+
+    FROM pretix/standalone:stable
+    USER root
+    RUN pip3 install pretix-passbook
+    USER pretixuser
+    RUN cd /pretix/src && make production
+
+Then, go to that directory and build the image::
+
+    $ docker build . -t mypretix
+
+You can now use that image ``mypretix`` instead of ``pretix/standalone`` in your service file (see above). Be sure
+to re-build your custom image after you pulled ``pretix/standalone`` if you want to perform an update.
+
+Scaling up
+----------
+
+If you need to scale to multiple machines, please first read our :ref:`scaling guide <scaling>`.
+
+If you run the official docker container on multiple machines, it is recommended to set the environment
+variable ``AUTOMIGRATE=skip`` on all containers and run ``docker exec -it pretix.service pretix migrate``
+on one machine after each upgrade manually, otherwise multiple containers might try to upgrade the
+database schema at the same time.
+
+To run only the ``pretix-web`` component of pretix as well as a nginx server serving static files, you
+can invoke the container with ``docker run … pretix/standalone:stable web`` (instead of ``all``). You
+can adjust the number of ``gunicorn`` processes with the ``NUM_WORKERS`` environment variable (defaults to
+two times the number of CPUs detected).
+
+To run only ``pretix-worker``, you can run ``docker run … pretix/standalone:stable taskworker``. You can
+also pass arguments to limit the worker to specific queues or to change the number of concurrent task
+workers, e.g. ``docker run … taskworker -Q notifications --concurrency 32``.

+
+Installing pretix Enterprise plugins
+====================================
+
+If you want to use a feature of pretix that is part of our commercial offering pretix Enterprise, you need to follow
+some extra steps. Installation works similar to normal pretix plugins, but involves a few extra steps.
+
+Buying the license
+------------------
+
+To obtain a license, please get in touch at sales@pretix.eu. Please let us know how many tickets you roughly intend
+to sell per year and how many servers you want to use the plugin on. We recommend having a look at our `price list`_
+first.
+
+
+Manual installation
+-------------------
+
+First, generate an SSH key for the system user that you install pretix as. In our tutorial, that would be the user
+``pretix``. Choose an empty passphrase::
+
+    # su pretix
+    $ ssh-keygen
+    Generating public/private rsa key pair.
+    Enter file in which to save the key (/var/pretix/.ssh/id_rsa):
+    Enter passphrase (empty for no passphrase):
+    Enter same passphrase again:
+    Your identification has been saved in /var/pretix/.ssh/id_rsa.
+    Your public key has been saved in /var/pretix/.ssh/id_rsa.pub.
+
+Next, send the content of the *public* key to your sales representative at pretix::
+
+    $ cat /var/pretix/.ssh/id_rsa.pub
+    ssh-rsa AAAAB3N...744HZawHlD pretix@foo
+
+After we configured your key in our system, you can install the plugin directly using ``pip`` from the URL we told
+you, for example::
+
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install -U "git+ssh://git@code.rami.io:10022/pretix/pretix-slack.git@stable#egg=pretix-slack"
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+    # systemctl restart pretix-web pretix-worker
+
+Docker installation
+-------------------
+
+To install a plugin, you need to build your own docker image. To do so, create a new directory to work in. As a first
+step, generate a new SSH key in that directory to use for authentication with us::
+
+    $ cd /home/me/mypretixdocker
+    $ ssh-keygen -N "" -f id_pretix_enterprise
+
+Next, send the content of the *public* key to your sales representative at pretix::
+
+    $ cat id_pretix_enterprise.pub
+    ssh-rsa AAAAB3N...744HZawHlD pretix@foo
+
+After we configured your key in our system, you can add a ``Dockerfile`` in your directory that includes the newly
+generated key and installs the plugin from the URL we told you::
+
+    FROM pretix/standalone:stable
+    USER root
+    COPY id_pretix_enterprise /root/.ssh/id_rsa
+    COPY id_pretix_enterprise.pub /root/.ssh/id_rsa.pub
+    RUN chmod -R 0600 /root/.ssh && \
+        mkdir -p /etc/ssh && \
+        ssh-keyscan -t rsa -p 10022 code.rami.io >> /root/.ssh/known_hosts && \
+        echo StrictHostKeyChecking=no >> /root/.ssh/config && \
+        DJANGO_SETTINGS_MODULE= pip3 install -U "git+ssh://git@code.rami.io:10022/pretix/pretix-slack.git@stable#egg=pretix-slack" && \
+        cd /pretix/src && \
+        sudo -u pretixuser make production
+    USER pretixuser
+
+Then, build the image for docker::
+
+    $ docker build -t mypretix
+
+You can now use that image ``mypretix`` instead of ``pretix/standalone:stable`` in your ``/etc/systemd/system/pretix.service``
+service file. Be sure to re-build your custom image after you pulled ``pretix/standalone`` if you want to perform an
+update to a new version of pretix.

+General remarks
+===============
+
+Requirements
+------------
+To use pretix, you will need the following things:
+
+* **pretix** and the python packages it depends on
+
+* An **WSGI application server** (we recommend gunicorn)
+
+* A periodic task runner, e.g. ``cron``
+
+* **A database**. This needs to be a SQL-based that is supported by Django. We highly recommend to either
+  go for **PostgreSQL**. If you do not provide one, pretix will run on SQLite, which is useful
+  for evaluation and development purposes.
+
+  .. warning:: Do not ever use SQLite in production. It will break.
+
+* A **reverse proxy**. pretix needs to deliver some static content to your users (e.g. CSS, images, ...). While pretix
+  is capable of doing this, having this handled by a proper web server like **nginx** or **Apache** will be much
+  faster. Also, you need a proxying web server in front to provide SSL encryption.
+
+  .. warning:: Do not ever run without SSL in production. Your users deserve encrypted connections and thanks to
+               `Let's Encrypt`_ SSL certificates can be obtained for free these days.
+
+* A **redis** server. This will be used for caching, session storage and task queuing.
+
+  .. warning:: pretix can run without redis, however this is only intended for development and should never be
+               used in production.
+
+* Optionally: RabbitMQ or memcached. Both of them might provide speedups, but if they are not present,
+  redis will take over their job.

+that everything is being run on one host and you don't expect thousands of participants trying to get a ticket within
+a few minutes. In this setup, you will have to perform a number of manual steps. If you prefer using a container

+             get it right. If you're not feeling comfortable managing a Linux server, check out our hosting and service
+             offers at `pretix.eu`_.
+
+We tested this guide on the Linux distribution **Debian 12** but it should work very similar on other
+modern distributions, especially on all systemd-based ones.
+
+Requirements
+------------
+
+Please set up the following systems beforehand, we'll not explain them here in detail (but see these links for external
+installation guides):
+
+* A python 3.9+ installation
+* A SMTP server to send out mails, e.g. `Postfix`_ on your machine or some third-party server you have credentials for
+* A HTTP reverse proxy, e.g. `nginx`_ or Apache to allow HTTPS connections
+* A `PostgreSQL`_ 12+ database server
+* A `redis`_ server
+* A `nodejs`_ installation
+
+We also recommend that you use a firewall, although this is not a pretix-specific recommendation. If you're new to
+Linux and firewalls, we recommend that you start with `ufw`_.
+
+.. note:: Please, do not run pretix without HTTPS encryption. You'll handle user data and thanks to `Let's Encrypt`_
+          SSL certificates can be obtained for free these days. We also *do not* provide support for HTTP-only
+          installations except for evaluation purposes.
+
+Unix user
+---------
+
+As we do not want to run pretix as root, we first create a new unprivileged user::
+
+    # adduser pretix --disabled-password --home /var/pretix
+
+In this guide, all code lines prepended with a ``#`` symbol are commands that you need to execute on your server as
+``root`` user (e.g. using ``sudo``); all lines prepended with a ``$`` symbol should be run by the unprivileged user.
+
+Database
+--------
+
+Having the database server installed, we still need a database and a database user. We can create these with any kind
+of database managing tool or directly on our database's shell. Please make sure that UTF8 is used as encoding for the
+best compatibility. You can check this with the following command::
+
+    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
+
+For PostgreSQL database creation, we would do::
+
+    # sudo -u postgres createuser pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+Package dependencies
+--------------------
+
+To build and run pretix, you will need the following debian packages::
+
+    # apt-get install git build-essential python3-dev python3-venv python3 python3-pip \
+                      libxml2-dev libxslt1-dev libffi-dev zlib1g-dev libssl-dev \
+                      gettext libpq-dev libjpeg-dev libopenjp2-7-dev
+
+Config file
+-----------
+
+We now create a config directory and config file for pretix::
+
+    # mkdir /etc/pretix
+    # touch /etc/pretix/pretix.cfg
+    # chown -R pretix:pretix /etc/pretix/
+    # chmod 0600 /etc/pretix/pretix.cfg
+
+Fill the configuration file ``/etc/pretix/pretix.cfg`` with the following content (adjusted to your environment)::
+
+    [pretix]
+    instance_name=My pretix installation
+    url=https://pretix.mydomain.com
+    currency=EUR
+    datadir=/var/pretix/data
+    trust_x_forwarded_for=on
+    trust_x_forwarded_proto=on
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    ; For PostgreSQL on the same host, we don't need a password because we can use
+    ; peer authentication if our PostgreSQL user matches our unix user.
+    password=
+    ; For local postgres authentication, you can leave it empty
+    host=
+
+    [mail]
+    ; See config file documentation for more options
+    from=tickets@yourdomain.com
+    host=127.0.0.1
+
+    [redis]
+    location=redis://127.0.0.1/0
+    sessions=true
+
+    [celery]
+    backend=redis://127.0.0.1/1
+    broker=redis://127.0.0.1/2
+
+See :ref:`email configuration <mail-settings>` to learn more about configuring mail features.
+
+Install pretix from PyPI
+------------------------
+
+Now we will install pretix itself. The following steps are to be executed as the ``pretix`` user. Before we
+actually install pretix, we will create a virtual environment to isolate the python packages from your global
+python installation::
+
+    # sudo -u pretix -s
+    $ python3 -m venv /var/pretix/venv
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install -U pip setuptools wheel
+
+We now install pretix, its direct dependencies and gunicorn::
+
+    (venv)$ pip3 install pretix gunicorn
+
+Note that you need Python 3.9 or newer. You can find out your Python version using ``python -V``.
+
+We also need to create a data directory and allow your webserver to traverse to the root directory::
+
+    (venv)$ mkdir -p /var/pretix/data/media
+    (venv)$ chmod +x /var/pretix
+
+Finally, we compile static files and translation data and create the database structure::
+
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+
+
+Start pretix as a service
+-------------------------
+
+We recommend starting pretix using systemd to make sure it runs correctly after a reboot. Create a file
+named ``/etc/systemd/system/pretix-web.service`` with the following content::
+
+    [Unit]
+    Description=pretix web service
+    After=network.target
+
+    [Service]
+    User=pretix
+    Group=pretix
+    Environment="VIRTUAL_ENV=/var/pretix/venv"
+    Environment="PATH=/var/pretix/venv/bin:/usr/local/bin:/usr/bin:/bin"
+    ExecStart=/var/pretix/venv/bin/gunicorn pretix.wsgi \
+                          --name pretix --workers 5 \
+                          --max-requests 1200  --max-requests-jitter 50 \
+                          --log-level=info --bind=127.0.0.1:8345
+    WorkingDirectory=/var/pretix
+    Restart=on-failure
+
+    [Install]
+    WantedBy=multi-user.target
+
+For background tasks we need a second service ``/etc/systemd/system/pretix-worker.service`` with the following content::
+
+    [Unit]
+    Description=pretix background worker
+    After=network.target
+
+    [Service]
+    User=pretix
+    Group=pretix
+    Environment="VIRTUAL_ENV=/var/pretix/venv"
+    Environment="PATH=/var/pretix/venv/bin:/usr/local/bin:/usr/bin:/bin"
+    ExecStart=/var/pretix/venv/bin/celery -A pretix.celery_app worker -l info
+    WorkingDirectory=/var/pretix
+    Restart=on-failure
+
+    [Install]
+    WantedBy=multi-user.target
+
+You can now run the following commands to enable and start the services::
+
+    # systemctl daemon-reload
+    # systemctl enable pretix-web pretix-worker
+    # systemctl start pretix-web pretix-worker
+
+
+Cronjob
+-------
+
+You need to set up a cronjob that runs the management command ``runperiodic``. The exact interval is not important
+but should be something between every minute and every hour. You could for example configure cron like this::
+
+    15,45 * * * * export PATH=/var/pretix/venv/bin:$PATH && cd /var/pretix && python -m pretix runperiodic
+
+The cronjob should run as the ``pretix`` user (``crontab -e -u pretix``).
+
+SSL
+---
+
+The following snippet is an example on how to configure a nginx proxy for pretix::
+
+    server {
+        listen 80 default_server;
+        listen [::]:80 ipv6only=on default_server;
+        server_name pretix.mydomain.com;
+        location / {
+            return 301 https://$host$request_uri;
+        }
+    }
+    server {
+        listen 443 default_server;
+        listen [::]:443 ipv6only=on default_server;
+        server_name pretix.mydomain.com;
+
+        ssl on;
+        ssl_certificate /path/to/cert.chain.pem;
+        ssl_certificate_key /path/to/key.pem;
+
+        add_header Referrer-Policy same-origin;
+        add_header X-Content-Type-Options nosniff;
+
+        location / {
+            proxy_pass http://localhost:8345;
+            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+            proxy_set_header X-Forwarded-Proto https;
+            proxy_set_header Host $http_host;
+        }
+
+        location /media/ {
+            alias /var/pretix/data/media/;
+            expires 7d;
+            access_log off;
+        }
+
+        location ^~ /media/cachedfiles {
+            deny all;
+            return 404;
+        }
+        location ^~ /media/invoices {
+            deny all;
+            return 404;
+        }
+
+        location /static/ {
+            alias /var/pretix/venv/lib/python3.11/site-packages/pretix/static.dist/;
+            access_log off;
+            expires 365d;
+            add_header Cache-Control "public";
+        }
+    }
+
+.. note:: Remember to replace the ``python3.11`` in the ``/static/`` path in the config
+          above with your python version.
+
+We recommend reading about setting `strong encryption settings`_ for your web server.
+
+Next steps
+----------
+
+Yay, you are done! You should now be able to reach pretix at https://pretix.yourdomain.com/control/ and log in as
+*admin@localhost* with a password of *admin*. Don't forget to change that password! Create an organizer first, then
+create an event and start selling tickets!
+
+You should probably read :ref:`maintainance` next.
+
+.. _`manual_updates`:
+
+Updates
+-------
+
+.. warning:: While we try hard not to break things, **please perform a backup before every upgrade**.
+
+To upgrade to a new pretix release, pull the latest code changes and run the following commands::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install -U --upgrade-strategy eager pretix gunicorn
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+    (venv)$ python -m pretix updateassets
+    # systemctl restart pretix-web pretix-worker
+
+Make sure to also read :ref:`update_notes` and the release notes of the version you are updating to. Pay special
+attention to the "Runtime and server environment" section of all release notes between your current and new version.
+
+.. _`manual_plugininstall`:
+
+Install a plugin
+----------------
+
+To install a plugin, just use ``pip``! Depending on the plugin, you should probably apply database migrations and
+rebuild the static files afterwards. Replace ``pretix-passbook`` with the plugin of your choice in the following
+example::
+
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install pretix-passbook
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+    # systemctl restart pretix-web pretix-worker
+
+System updates
+--------------
+
+After system updates, such as updates to a new Ubuntu or Debian release, you might be using a new Python version.
+That's great, but requires some adjustments. First, adjust any old version paths in your nginx configuration file.
+Then, re-create your Python environment::
+
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 freeze > /tmp/pip-backup.txt
+    $ rm -rf /var/pretix/venv
+    $ python3 -m venv /var/pretix/venv
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ pip3 install -U pip wheel setuptools
+    (venv)$ pip3 install -r /tmp/pip-backup.txt
+
+Then, proceed like after any plugin installation::
+
+    (venv)$ python -m pretix migrate
+    (venv)$ python -m pretix rebuild
+    (venv)$ python -m pretix updateassets
+    # systemctl restart pretix-web pretix-worker

+
+Backups and Monitoring
+======================
+
+If you host your own pretix instance, you also need to care about the availability
+of your service and the safety of your data yourself. This page gives you some
+information that you might need to do so properly.
+
+.. _`backups`:
+
+Backups
+-------
+
+There are essentially two things which you should create backups of:
+
+Database
+    Your SQL database. This is critical and you should **absolutely always create automatic
+    backups of your database**. There are tons of tutorials on the internet on how to do this,
+    and the exact process depends on the choice of your database. For PostgreSQL, see the
+    ``pg_dump`` tool. You probably want to create a cronjob that does the backups for you on a
+    regular schedule.
+
+Data directory
+    The data directory of your pretix configuration might contain some things that you should
+    back up. If you did not specify a secret in your config file, back up the ``.secret`` text
+    file in the data directory. If you lose your secret, all currently active user sessions,
+    password reset links and similar things will be rendered invalid. Also, you probably want
+    to backup the ``media`` subdirectory of the data directory which contains all user-uploaded
+    and generated files. This includes files you could in theory regenerate (ticket downloads)
+    but also files that you might be legally required to keep (invoice PDFs) or files that you
+    would need to re-upload (event logos, product pictures, etc.). It is up to you if you
+    create regular backups of this data, but we strongly advise you to do so. You can create
+    backups e.g. using ``rsync``. There is a lot of information on the internet on how to create
+    backups of folders on a Linux machine.
+
+There is no need to create backups of the redis database, if you use it. We only use it for
+non-critical, temporary or cached data.
+
+Uptime monitoring
+-----------------
+
+To monitor whether your pretix instance is running, you can issue a GET request to
+``https://pretix.mydomain.com/healthcheck/``. This endpoint tests if the connection to the
+database, to the configured cache and to redis (if used) is working correctly. If everything
+appears to work fine, an empty response with status code ``200`` is returned.
+If there is a problem, a status code in the ``5xx`` range will be returned.
+
+.. _`perf-monitoring`:
+
+Performance monitoring
+----------------------
+
+If you want to generate detailed performance statistics of your pretix installation, there is an
+endpoint at ``https://pretix.mydomain.com/metrics`` (no slash at the end) which returns a
+number of values in the text format understood by monitoring tools like Prometheus_. This data
+is only collected and exposed if you enable it in the :ref:`metrics-settings` section of your
+pretix configuration. You can also configure basic auth credentials there to protect your
+statistics against unauthorized access. The data is temporarily collected in redis, so the
+performance impact of this feature depends on the connection to your redis database.
+
+Currently, mostly response times of HTTP requests and background tasks are exposed.
+
+If you want to go even further, you can set the ``profile`` option in the :ref:`django-settings`
+section to a value between 0 and 1. If you set it for example to 0.1, then 10% of your requests
+(randomly selected) will be run with cProfile_ activated. The profiling results will be saved
+to your data directory. As this might impact performance significantly and writes a lot of data
+to disk, we recommend to only enable it for a small number of requests -- and only if you are
+really interested in the results.
+
+Available metrics
+^^^^^^^^^^^^^^^^^
+
+The metrics available in pretix follow the standard `metric types`_ from the Prometheus world.
+Currently, the following metrics are exported:
+
+pretix_view_requests_total
+    Counter. Counts requests to Django views, labeled with the resolved ``url_name``, the used
+    HTTP ``method`` and the ``status_code`` returned.
+
+pretix_view_durations_seconds
+    Histogram. Measures duration of requests to Django views, labeled with the resolved
+    ``url_name``, the used HTTP ``method`` and the ``status_code`` returned.
+
+pretix_task_runs_total
+    Counter. Counts executions of background tasks, labeled with the ``task_name`` and the
+    ``status``. The latter can be ``success``, ``error`` or ``expected-error``.
+
+pretix_task_duration_seconds
+    Histogram. Measures duration of successful background task executions, labeled with the
+    ``task_name``.
+
+pretix_model_instances
+    Gauge. Measures number of instances of a certain model within the database, labeled with
+    the ``model`` name. Starting with pretix 3.11, these numbers might only be approximate for
+    most tables when running on PostgreSQL to mitigate performance impact.
+
+pretix_celery_tasks_queued_count
+    The number of background tasks in the worker queue, labeled with ``queue``.
+
+pretix_celery_tasks_queued_age_seconds
+    The age of the longest-waiting in the worker queue in seconds, labeled with ``queue``.
+
+pretix_logins_successful
+    Counter. The number of successful backend logins.
+
+pretix_logins_failed
+    Counter. The number of failed backend logins, labeled with ``reason``.

+
+Migrating from MySQL/MariaDB to PostgreSQL
+==========================================
+
+Our recommended database for all production installations is PostgreSQL. Support for MySQL/MariaDB has been removed
+in newer pretix releases.
+
+In order to follow this guide, your pretix installation needs to be a version that fully supports MySQL/MariaDB. If you
+already upgraded to pretix 5.0 or later, downgrade back to the last 4.x release using ``pip``.
+
+.. note:: We have tested this guide carefully, but we can't assume any liability for its correctness. The data loss
+          risk should be low as long as pretix is not running while you do the migration. If you are a pretix Enterprise
+          customer, feel free to reach out in advance if you want us to support you along the way.
+
+Update database schema
+----------------------
+
+Before you start, make sure your database schema is up to date. With a local installation::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+With a docker installation::
+
+    docker exec -it pretix.service pretix migrate
+
+
+Install PostgreSQL
+------------------
+
+Now, install and set up a PostgreSQL server. For a local installation on Debian or Ubuntu, use::
+
+    # apt install postgresql
+
+Having the database server installed, we still need a database and a database user. We can create these with any kind
+of database managing tool or directly on our database's shell. Please make sure that UTF8 is used as encoding for the
+best compatibility. You can check this with the following command::
+
+    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
+
+Without Docker
+""""""""""""""
+
+For our standard manual installation, create the database and user like this::
+
+    # sudo -u postgres createuser pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+With Docker
+"""""""""""
+
+For our standard docker installation, create the database and user like this::
+
+    # sudo -u postgres createuser -P pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+Make sure that your database listens on the network. If PostgreSQL on the same same host as docker, but not inside a docker container, we recommend that you listen on the Docker interface by changing the following line in ``/etc/postgresql/<version>/main/postgresql.conf``::
+
+    listen_addresses = 'localhost,172.17.0.1'
+
+You also need to add a new line to ``/etc/postgresql/<version>/main/pg_hba.conf`` to allow network connections to this user and database::
+
+    host    pretix          pretix          172.17.0.1/16           md5
+
+Restart PostgreSQL after you changed these files::
+
+    # systemctl restart postgresql
+
+If you have a firewall running, you should also make sure that port 5432 is reachable from the ``172.17.0.1/16`` subnet.
+
+Of course, instead of all this you can also run a PostgreSQL docker container and link it to the pretix container.
+
+Stop pretix
+-----------
+
+To prevent any more changes to your data, stop pretix from running. With a local installation::
+
+    # systemctl stop pretix-web pretix-worker
+
+With docker::
+
+    # systemctl stop pretix
+
+Change configuration
+--------------------
+
+Change the database configuration in your ``/etc/pretix/pretix.cfg`` file::
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    password=  ; only required for docker or remote database, can be kept empty for local auth
+    host=      ; set to 172.17.0.1 in docker setup, keep empty for local auth
+
+
+Create database schema
+-----------------------
+
+To create the schema in your new PostgreSQL database, use the following commands. With a local installation::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+With docker::
+
+    # docker run --rm -v /var/pretix-data:/data -v /etc/pretix:/etc/pretix -v /var/run/redis:/var/run/redis pretix/standalone:stable migrate
+
+
+Migrate your data
+-----------------
+
+Install ``pgloader``::
+
+    # apt install pgloader
+
+.. note::
+
+   If you are using Ubuntu 20.04, the ``pgloader`` version from the repositories seems to be incompatible with PostgreSQL
+   12+. You can install ``pgloader`` from the `PostgreSQL repositories`_ instead.
+   See also `this discussion <https://github.com/pretix/pretix/issues/3090>`_.
+
+Create a new file ``/tmp/pretix.load``, replacing the MySQL and PostgreSQL connection strings with the correct user names, passwords, and/or database names::
+
+    LOAD DATABASE
+        FROM mysql://pretix:password@localhost/pretix  -- replace with mysql://username:password@hostname/dbname
+        INTO postgresql:///pretix                      -- replace with dbname
+
+    WITH data only, include no drop, truncate, disable triggers,
+         create no indexes, drop indexes, reset sequences
+
+    ALTER SCHEMA 'pretix' RENAME TO 'public'           -- replace pretix with the name of the MySQL database
+
+    ALTER TABLE NAMES MATCHING ~/.*/
+        SET SCHEMA 'public'
+
+    SET timezone TO '+00:00'
+
+    SET PostgreSQL PARAMETERS
+         maintenance_work_mem to '128MB',
+         work_mem to '12MB';
+
+Then, run::
+
+    # sudo -u postgres pgloader /tmp/pretix.load
+
+The output should end with a table summarizing the results for every table. You can ignore warnings about type casts
+and missing constraints.
+
+Afterwards, delete the file again::
+
+    # rm -rf /tmp/pretix.load
+
+Start pretix
+------------
+
+Stop your MySQL server as a verification step that you are no longer using it::
+
+    # systemctl stop mariadb
+
+Then, restart pretix. With a local installation::
+
+    # systemctl start pretix-web pretix-worker
+
+With a docker installation::
+
+    # systemctl start pretix
+
+And you're done! After you've verified everything has been copied correctly, you can delete the old MySQL database.
+
+.. note:: Don't forget to update your backup process to back up your PostgreSQL database instead of your MySQL database now.
+
+Troubleshooting
+---------------
+
+Peer authentication failed
+""""""""""""""""""""""""""
+
+Sometimes you might see an error message like this::
+
+    django.db.utils.OperationalError: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL:  Peer authentication failed for user "pretix"
+
+It is important to understand that PostgreSQL by default offers two types of authentication:
+
+- **Peer authentication**, which works automatically based on the Linux user you are working as. This requires that
+  the connection is made through a local socket (empty ``host=`` in ``pretix.cfg``) and the name of the PostgreSQL user
+  and the Linux user are identical.
+
+  - Typically, you might run into this error if you accidentally execute ``python -m pretix`` commands as root instead
+    of the ``pretix`` user.
+
+- **Password authentication**, which requires a username and password and works over network connections. To force
+  password authentication instead of peer authentication, set ``host=127.0.0.1`` in ``pretix.cfg``.
+
+  - You can alter the password on a PostgreSQL shell using the command ``ALTER USER pretix WITH PASSWORD '***';``.
+    When creating a user with the ``createuser`` command, pass option ``-P`` to set a new password.
+
+  - Even with password authentication, PostgreSQL by default only allows local connections. To allow remote connections,
+    you need to adjust both the ``listen_address`` configuration parameter as well as the ``pg_hba.conf`` file (see above
+    for an example with the docker networking setup).
+
+Database error: relation does not exist
+"""""""""""""""""""""""""""""""""""""""
+
+If you see an error like this::

+
+Scaling guide
+=============
+
+Our :ref:`installation guide <installation>` only covers "small-scale" setups, by which we mostly mean
+setups that run on a **single (virtual) machine** and do not encounter large traffic peaks.
+
+We do not offer an installation guide for larger-scale setups of pretix, mostly because we believe that
+there is no one-size-fits-all solution for this and the desired setup highly depends on your use case,
+the platform you run pretix on, and your technical capabilities. We do not recommend trying set up pretix
+in a multi-server environment if you do not already have experience with managing server clusters.
+
+This document is intended to give you a general idea on what issues you will encounter when you scale up
+and what you should think of.
+
+.. tip::
+
+   If you require more help on this, we're happy to help. Our pretix Enterprise support team has built
+   and helped building, scaling and load-testing pretix installations at any scale and we're looking
+   forward to work with you on fine-tuning your system. If you intend to sell **more than a thousand
+   tickets in a very short amount of time**, we highly recommend reaching out and at least talking this
+   through. Just get in touch at sales@pretix.eu!
+
+Scaling reasons
+---------------
+
+There are two main reasons for scaling up a pretix installation beyond a single server:
+
+* **Availability:** Distributing pretix over multiple servers can allow you to survive failure of one or more single machines, leading to a higher uptime and reliability of your system.
+
+* **Traffic and throughput:** Distributing pretix over multiple servers can allow you to process more web requests and ticket sales at the same time.
+
+You are very unlikely to require scaling for other reasons, such as having too much data in your database.
+
+Components
+----------
+
+A pretix installation usually consists of the following components which run performance-relevant processes:
+
+* ``pretix-web`` is the Django-based web application that serves all user interaction.
+
+* ``pretix-worker`` is a Celery-based application that processes tasks that should be run asynchronously outside of the web application process.
+
+* A **PostgreSQL database** keeps all the important data and processes the actual transactions.
+
+* A **web server** that terminates TLS and HTTP connections and forwards them to ``pretix-web``. In some cases, e.g. when serving static files, the web servers might return a response directly. We recommend using ``nginx``.
+
+* A **redis** server responsible for the communication between ``pretix-web`` and ``pretix-worker``, as well as for caching.
+
+* A directory of **media files** such as user-uploaded files or generated files (tickets, invoices, …) that are created and used by ``pretix-web``, ``pretix-worker`` and the web server.
+
+In the following, we will discuss the scaling behavior of every component individually. In general, you can run all of the components
+on the same server, but you can just as well distribute every component to its own server, or even use multiple servers for some single
+components.
+
+.. warning::
+
+   When setting up your system, don't forget about security. In a multi-server environment,
+   you need to take special care to ensure that no unauthorized access to your database
+   is possible through the network and that it's not easy to wiretap your connections. We
+   recommend a rigorous use of firewalls and encryption on all communications. You can
+   ensure this either on an application level (such as using the TLS support in your
+   database) or on a network level with a VPN solution.
+
+Web server
+""""""""""
+
+Your web server is at the very front of your installation. It will need to absorb all of the traffic, and it should be able to
+at least show a decent error message, even when everything else fails. Luckily, web servers are really fast these days, so this
+can be achieved without too much work.
+
+We recommend reading up on tuning your web server for high concurrency. For nginx, this means thinking about the number of worker
+processes and the number of connections each worker process accepts. Double-check that TLS session caching works, because TLS
+handshakes can get really expensive.
+
+During a traffic peak, your web server will be able to make use of more CPU resources, while memory usage will stay comparatively low,
+so if you invest in more hardware here, invest in more and faster CPU cores.
+
+Make sure that pretix' static files (such as CSS and JavaScript assets) as well as user-uploaded media files (event logos, etc)
+are served directly by your web server and your web server caches them in-memory (nginx does it by default) and sets useful
+headers for client-side caching. As an additional performance improvement, you can turn of access logging for these types of files.
+If you want, you can even farm out serving static files to a different web server entirely and :ref:`configure pretix to reference
+them from a different URL <config-urls>`.
+
+.. tip::
+
+   If you expect *really high traffic* for your very popular event, you might want to do some rate limiting on this layer, or,
+   if you want to ensure a fair and robust first-come-first-served experience and prefer letting users wait over showing them
+   errors, consider a queuing solution. We're happy to provide you with such systems, just get in touch at sales@pretix.eu.
+
+pretix-web
+""""""""""
+
+The ``pretix-web`` process does not carry any internal state and can be easily started on as many machines as you like, and you can
+use the load balancing features of your frontend web server to redirect to all of them.
+
+You can adjust the number of processes in the ``gunicorn`` command line, and we recommend choosing roughly two times the number
+of CPU cores available. Under load, the memory consumption of ``pretix-web`` will stay comparatively constant, while the CPU usage
+will increase a lot. Therefore, if you can add more or faster CPU cores, you will be able to serve more users.
+
+pretix-worker
+"""""""""""""
+
+The ``pretix-worker`` process performs all operations that are not directly executed in the request-response-cycle of ``pretix-web``.
+Just like ``pretix-web`` you can easily start up as many instances as you want on different machines to share the work. As long as they
+all talk to the same redis server, they will all receive tasks from ``pretix-web``, work on them and post their result back.
+You can configure the number of threads that run tasks in parallel through the ``--concurrency`` command line option of ``celery``.
+
+Just like ``pretix-web``, this process is mostly heavy on CPU, disk IO and network IO, although memory peaks can occur e.g. during the
+generation of large PDF files, so we recommend having some reserves here.
+
+``pretix-worker`` performs a variety of tasks which are of different importance.
+Some of them are mission-critical and need to be run quickly even during high load (such as
+creating a cart or an order), others are irrelevant and can easily run later (such as
+distributing tickets on the waiting list). You can fine-tune the capacity you assign to each
+of these tasks by running ``pretix-worker`` processes that only work on a specific **queue**.
+For example, you could have three servers dedicated only to process order creations and one
+server dedicated only to sending emails. This allows you to set priorities and also protects
+you from e.g. a slow email server lowering your ticket throughput.
+
+You can do so by specifying one or more queues on the ``celery`` command line of this process, such as ``celery -A pretix.celery_app worker -Q notifications,mail``. Currently,
+the following queues exist:
+
+* ``checkout`` -- This queue handles everything related to carts and orders and thereby everything required to process a sale. This includes adding and deleting items from carts as well as creating and canceling orders.
+
+* ``mail`` -- This queue handles sending of outgoing emails.
+
+* ``notifications`` -- This queue handles the processing of any outgoing notifications, such as email notifications to admin users (except for the actual sending) or API notifications to registered webhooks.
+
+* ``background`` -- This queue handles tasks that are expected to take long or have no human waiting for their result immediately, such as refreshing caches, re-generating CSS files, assigning tickets on the waiting list or parsing bank data files.
+
+* ``default`` -- This queue handles everything else with "medium" or unassigned priority, most prominently the generation of files for tickets, invoices, badges, admin exports, etc.
+
+Media files
+"""""""""""
+
+Both ``pretix-web``, ``pretix-worker`` and in some cases your webserver need to work with
+media files. Media files are all files generated *at runtime* by the software. This can
+include files uploaded by the event organizers, such as the event logo, files uploaded by
+ticket buyers (if you use such features) or files generated by the software, such as
+ticket files, invoice PDFs, data exports or customized CSS files.
+
+Those files are by default stored to the ``media/`` sub-folder of the data directory given
+in the ``pretix.cfg`` configuration file. Inside that ``media/`` folder, you will find a
+``pub/`` folder containing the subset of files that should be publicly accessible through
+the web server. Everything else only needs to be accessible by ``pretix-web`` and
+``pretix-worker`` themselves.
+
+If you distribute ``pretix-web`` or ``pretix-worker`` across more than one machine, you
+**must** make sure that they all have access to a shared storage to read and write these
+files, otherwise you **will** run into errors with the user interface.
+
+The easiest solution for this is probably to store them on a NFS server that you mount
+on each of the other servers.
+
+Since we use Django's file storage mechanism internally, you can in theory also use an object-storage solution like Amazon S3, Ceph, or Minio to store these files, although we currently do not expose this through pretix' configuration file and this would require you to ship your own variant of ``pretix/settings.py`` and reference it through the ``DJANGO_SETTINGS_MODULE`` environment variable.
+
+At pretix.eu, we use a custom-built `object storage cluster`_.
+
+SQL database
+""""""""""""
+
+One of the most critical parts of the whole setup is the SQL database -- and certainly the
+hardest to scale. Tuning relational databases is an art form, and while there's lots of
+material on it on the internet, there's not a single recipe that you can apply to every case.
+
+As a general rule of thumb, the more resources you can give your databases, the better.
+Most databases will happily use all CPU cores available, but only use memory up to an amount
+you configure, so make sure to set this memory usage as high as you can afford. Having more
+memory available allows your database to make more use of caching, which is usually good.
+
+Scaling your database to multiple machines needs to be treated with great caution. It's a
+good idea to have a replica of your database for availability reasons. In case your primary
+database server fails, you can easily switch over to the replica and continue working.
+
+However, using database replicas for performance gain is much more complicated. When using
+replicated database systems, you are always trading in consistency or availability to get
+additional performance and the consequences of this can be subtle. It is important
+that you have a deep understanding of the semantics of your replication mechanism.
+
+.. warning::
+
+   Using an off-the-shelf database proxy solution that redirects read queries to your
+   replicas and write queries to your primary database **will lead to very nasty bugs.**
+
+   As an example, if you buy a ticket, pretix first needs to calculate how many tickets
+   are left to sell. If this calculation is done on a database replica that lags behind
+   even for fractions of a second, the decision to allow selling the ticket will be made
+   on stale data and you can end up with more tickets sold than configured. Similarly,
+   you could imagine situations leading to double payments etc.
+
+If you do have a replica, you *can* tell pretix about it :ref:`in your configuration <config-replica>`.
+This way, pretix can offload complex read-only queries to the replica when it is safe to do so.
+As of pretix 2.7, this is mainly used for search queries in the backend and for rendering the
+product list and event lists in the frontend, but we plan on expanding this in the future.
+
+Therefore, for now our clear recommendation is: Try to scale your database vertically and put
+it on the most powerful machine you have available.
+
+redis
+"""""
+
+While redis is a very important part that glues together some of the components, it isn't used
+heavily and can usually handle a fairly large pretix installation easily on a single modern
+CPU core.
+Having some memory available is good, e.g. if lots of tasks queue up during a traffic peak, but we wouldn't expect ever needing more than a gigabyte of it.
+
+Feel free to set up a redis cluster for availability – but you probably won't need it for performance.
+
+The limitations
+---------------
+
+Up to a certain point, pretix scales really well. However, there are a few things that we consider
+even more important than scalability, and those are correctness and reliability. We want you to be
+able to trust that pretix will not sell more tickets than you intended or run into similar error
+cases.
+
+Combined with pretix' flexibility and complexity, especially around vouchers and quotas, this creates
+some hard issues. In many cases, we need to fall back to event-global locking for some actions which
+are likely to run with high concurrency and cause harm.
+
+For every event, only one of these locking actions can be run at the same time. Examples for this are
+adding products limited by a quota to a cart, adding items to a cart using a voucher or placing an order
+consisting of cart positions that don't have a valid reservation for much longer. In these cases, it is
+currently not realistically possible to exceed selling **approx. 500 orders per minute per event**, even
+if you add more hardware.
+If you have an unlimited number of tickets, we can apply fewer locking and we've reached **approx.
+1500 orders per minute per event** in benchmarks, although even more should be possible.
+
+We're working on reducing the number of cases in which this is relevant and thereby improve the possible
+throughput. If you want to use pretix for an event with 10,000+ tickets that are likely to be sold out
+within minutes, please get in touch to discuss possible solutions. We'll work something out for you!

+Update notes
+============
+
+pretix receives regular feature and bugfix updates and we highly encourage you to always update to
+the latest version for maximum quality and security. Updates are announces on our `blog`_. There are
+usually 10 feature updates in a year, so you can expect a new release almost every month.
+
+Pure bugfix releases are only issued in case of very critical bugs or security vulnerabilities. In these
+case, we'll publish bugfix releases for the last three stable release branches.
+
+Compatibility to plugins and in very rare cases API clients may break. For in-depth details on the
+API changes of every version, please refer to the release notes published on our blog.
+
+Upgrade steps
+-------------
+
+For the actual upgrade, you can usually just follow the steps from the installation guide for :ref:`manual installations <manual_updates>`
+or :ref:`docker installations <docker_updates>` respectively.
+Generally, it is always strongly recommended to perform a :ref:`backup <backups>` first.
+It is possible to skip versions during updates, although we recommend not skipping over major version numbers
+(i.e. if you want to go from 2.4 to 4.4, first upgrade to 3.0, then upgrade to 4.0, then to 4.4).
+
+In addition to these standard update steps, the following list issues steps that should be taken when you upgrade
+to specific versions for pretix. If you're skipping versions, please read the instructions for every version in
+between as well.
+
+Upgrade to 3.17.0 or newer
+""""""""""""""""""""""""""
+

+
+pretix 4.4 introduces a new data structure to store historical financial data. If you already have existing
+data in your database, you will need to back-fill this data or you might get incorrect reports! This is not
+done automatically as part of the usual update steps since it can take a while on large databases and you might
+want to do it in parallel while the system is already running again. Please execute the following command::
+
+    (venv)$ python -m pretix create_order_transactions
+
+Or, with a docker installation::
+
+    $ docker exec -it pretix.service pretix create_order_transactions

-Tax codes
----------
-
-For integration with external systems, such as electronic invoicing or bookkeeping systems, the tax rate itself is often
-not sufficient information. For example, there could be many different reasons why a sale has a tax rate of 0 %, but the
-external handling of the transaction depends on which reason applies. Therefore, pretix allows to supply a codified
-reason that allows us to understand what the specific legal situation is. These tax codes are modeled after a combination
-of the code lists from the European standard EN16931 and the German standard DSFinV-K.
-
-The following codes are supported:
-
-- ``S/standard`` -- Standard VAT rate in the merchant country
-- ``S/reduced`` -- Reduced VAT rate in the merchant country
-- ``S/averaged`` -- Averaged VAT rate in the merchant country (known use case: agricultural businesses in Germany)
-- ``AE`` -- Reverse charge
-- ``O`` -- Services outside of scope of tax
-- ``E`` -- Exempt from tax (no reason given)
-- ``E/<reason>`` -- Exempt from tax, where ``<reason>`` is one of the codes listed in the `VATEX code list`_ version 5.0.
-- ``Z`` -- Zero-rated goods
-- ``G`` -- Free export item, VAT not charged
-- ``K`` -- VAT exempt for EEA intra-community supply of goods and services
-- ``L`` -- Canary Islands general indirect tax
-- ``M`` -- Tax for production, services and importation in Ceuta and Melilla
-- ``B`` -- Transferred (VAT), only in Italy
-
-The code set in the ``code`` attribute of the tax rule is used by default. When ``eu_reverse_charge`` is active, the
-code is replaced by ``AE`` for reverse charge sales and by ``O`` for non-EU sales. When configuring custom rules, you
-should actively set a ``"code"`` key on each rule. Only for ``"action": "reverse"`` we automatically apply the code
-``AE``, in all other cases the default ``code`` of the tax rule is selected.

-Customizing log entry display

-
-The base ``LogEntryType`` classes allow for varying degree of customization in their descendants.
-
-If you want to add another log message for an existing core object (e.g. an :class:`Order <pretix.base.models.Order>`,
-:class:`Item <pretix.base.models.Item>`, or :class:`Voucher <pretix.base.models.Voucher>`), you can inherit
-from its predefined :class:`LogEntryType <pretix.base.logentrytypes.LogEntryType>`, e.g.
-:class:`OrderLogEntryType <pretix.base.logentrytypes.OrderLogEntryType>`, and just specify a new plaintext string.
-You can use format strings to insert information from the LogEntry's `data` object as shown in the section above.
-
-If you define a new model object in your plugin, you should make sure proper object links in the user interface are
-displayed for it. If your model object belongs logically to a pretix :class:`Event <pretix.base.models.Event>`, you can inherit from :class:`EventLogEntryType <pretix.base.logentrytypes.EventLogEntryType>`,
-and set the ``object_link_*`` fields accordingly. ``object_link_viewname`` refers to a django url name, which needs to
-accept the arguments `organizer` and `event`, containing the respective slugs, and additional arguments provided by
-``object_link_args``. The default implementation of ``object_link_args`` will return an argument named by
-````object_link_argname``, with a value of ``content_object.pk`` (the primary key of the model object).
-If you want to customize the name displayed for the object (instead of the result of calling ``str()`` on it),
-overwrite ``object_link_display_name``.

+ePayBL
+======
+
+.. note::
+
+    Since ePayBL is only available to german federal, provincial and communal entities, the following page is also
+    only provided in german. Should you require assistance with ePayBL and do not speak this language, please feel free
+    reach out to support@pretix.eu.
+
+
+Einführung
+----------
+
+.. note::
+
+    Sollten Sie lediglich schnell entscheiden wollen, welcher Kontierungsmodus in den Einstellungen des pretix
+    ePayBL-plugins gewählt werden soll, so springen Sie direkt zur Sektion :ref:`Kontierungsmodus`.
+
+
+`ePayBL`_ - das ePayment-System von Bund und Länder - ist das am weitesten verbreitete Zahlungssystem für Bundes-, Länder-
+sowie kommunale Aufgabenträger. Während es nur wie eines von vielen anderen Zahlungssystemen scheint, so bietet es
+seinen Nutzern besondere Vorteile, wie die automatische Erfassung von Zahlungsbelegen, dem Übertragen von Buchungen in
+Haushaltskassen/-systeme sowie die automatische Erfassung von Kontierungen und Steuermerkmalen.
+
+Rein technisch gesehen ist ePayBL hierbei nicht ein eigenständiger Zahlungsdienstleister sondern nur ein eine Komponente
+im komplexen System, dass die Zahlungsabwicklung für Kommunen und Behörden ist.
+
+Im folgenden der schematische Aufbau einer Umgebung, in welcher ePayBL zum Einsatz kommt:
+
+.. figure:: img/epaybl_flowchart.png
+   :class: screenshot
+
+   Quelle: Integrationshandbuch ePayBL-Konnektor, DResearch Digital Media Systems GmbH
+
+
+In diesem Schaubild stellt pretix, bzw. die von Ihnen als Veranstalter angelegten Ticketshops, das Fachverfahren dar.
+
+ePayBL stellt das Bindeglied zwischen den Fachverfahren, Haushaltssystemen und dem eigentlichen Zahlungsdienstleister,
+dem sog. ZV-Provider dar. Dieser ZV-Provider ist die Stelle, welche die eigentlichen Kundengelder einzieht und an den
+Händler auszahlt. Das Gros der Zahlungsdienstleister unterstützt pretix hierbei auch direkt; sprich: Sollten Sie die
+Anbindung an Ihre Haushaltssysteme nicht benötigen, kann eine direkte Anbindung in der Regel ebenso - und dies bei meist
+vermindertem Aufwand - vorgenommen werden.
+
+In der Vergangenheit zeigte sich jedoch schnell, dass nicht jeder IT-Dienstleister immer sofort die neueste Version von
+ePayBL seinen Nutzern angeboten hat. Die Gründe hierfür sind mannigfaltig: Von fest vorgegebenen Update-Zyklen bis hin
+zu Systeme mit speziellen Anpassungen, kann leider nicht davon ausgegangen werden, dass alle ePayBL-Systeme exakt gleich
+ansprechbar sind - auch wenn es sich dabei eigentlich um einen standardisierten Dienst handelt.
+
+Aus diesem Grund gibt es mit dem ePayBL-Konnektor eine weitere Abstraktionsschicht welche optional zwischen den
+Fachverfahren und dem ePayBL-Server sitzt. Dieser Konnektor wird so gepflegt, dass er zum einen eine dauerhaft
+gleichartige Schnittstelle den Fachverfahren bietet aber gleichzeitig auch mit jeder Version des ePayBL-Servers
+kommunizieren kann - egal wie neu oder alt, wie regulär oder angepasst diese ist.
+
+Im Grunde müsste daher eigentlich immer gesagt werden, dass pretix eine Anbindung an den ePayBL-Konnektor bietet; nicht
+an "ePayBL" oder den "ePayBL-Server". Diese Unterscheidung kann bei der Ersteinrichtung und Anforderung von Zugangsdaten
+von Relevanz sein. Da in der Praxis jedoch beide Begriffe gleichbedeutend genutzt werden, wird im Folgenden auch nur von
+einer ePayBL-Anbindung die Rede sein - auch wenn explizit der Konnektor gemeint ist.
+
+
+.. _`Kontierungsmodus`:
+
+Kontierungsmodus
+----------------
+
+ePayBL ist ein Produkt, welches für die Abwicklung von Online-Zahlungsvorgängen in der Verwaltung geschaffen wurde. Ein
+Umfeld, in dem klar definiert ist, was ein Kunde gerade bezahlt und wohin das Geld genau fließt. Diese Annahmen lassen
+sich in einem Ticketshop wie pretix jedoch nur teilweise genauso abbilden.
+
+Die ePayBL-Integration für pretix bietet daher zwei unterschiedliche Modi an, wie Buchungen erfasst und an ePayBL und
+damit auch an die dahinterliegenden Haushaltssysteme gemeldet werden können.
+
+Kontierung pro Position/Artikel
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Dieser Modus versucht den klassischen, behördentypischen ePayBL-Zahlungsvorgang abzubilden: Jede einzelne Position, die
+ein Kunde in den Warenkorb legt, wird auch genauso 1:1 an ePayBL und die Hintergrundsysteme übermittelt.
+
+Hierbei muss zwingend auch für jede Position ein Kennzeichen für Haushaltsstelle und Objektnummer, sowie optional ein
+Kontierungsobjekt (``HREF``; bspw. ``stsl=Steuerschlüssel;psp=gsb:Geschäftsbereich,auft:Innenauftrag,kst:Kostenstelle;``
+) übermittelt werden.
+
+Diese Daten sind vom Veranstalter entsprechend für jeden in der Veranstaltung angelegten Artikel innerhalb des Tabs
+"Zusätzliche Einstellungen" der Produkteinstellungen zu hinterlegen.
+
+Während diese Einstellung eine größtmögliche Menge an Kontierungsdaten überträgt und auch ein separates Verbuchen von
+Leistungen auf unterschiedliche Haushaltsstellen erlaubt, so hat diese Option auch einen großen Nachteil: Der Kunde kann
+nur eine Zahlung für seine Bestellung leisten.
+
+Während sich dies nicht nach einem großen Problem anhört, so kann dies beim Kunden zu Frust führen. pretix bietet die
+Option an, dass ein Veranstalter eine Bestellung jederzeit verändern kann: Ändern von Preisen von Positionen in einer
+aufgegebenen Bestellung, Zubuchen und Entfernen von Bestellpositionen, etc. Hat der Kunde seine ursprüngliche Bestellung
+jedoch schon bezahlt, kann pretix nicht mehr die komplette Bestellung mit den passenden Kontierungen übertragen - es
+müsste nur ein Differenz-Abbild zwischen Ursprungsbestellung und aktueller Bestellung übertragen werden. Aber auch wenn
+eine "Nachmeldung" möglich wäre, so wäre ein konkretes Auflösen für was jetzt genau gezahlt wird, nicht mehr möglich.
+
+Daher gilt bei der Nutzung der Kontierung pro Position/Artikel: Der Kunde kann nur eine (erfolgreiche) Zahlung auf seine
+Bestellung leisten.
+
+Eine weitere Einschränkung dieses Modus ist, dass aktuell keine Gebühren-Positionen (Versandkosten, Zahlungs-, Storno-
+oder Servicegebühren) in diesem Modus übertragen werden können. Bitte wenden Sie sich an uns, wenn Sie diese
+Funktionalität benötigen.
+
+
+Kontierung pro Zahlvorgang
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Dieser Modus verabschiedet sich vom behördlichen "Jede Position gehört genau zu einem Haushaltskonto und muss genau
+zugeordnet werden". Stattdessen werden alle Bestellpositionen - inklusive eventuell definierter Gebühren - vermengt und
+nur als ein großer Warenkorb, genauer gesagt: eine einzige Position an ePayBL sowie die Hintergrundsysteme gemeldet.
+
+Während im "pro Postion/Artikel"-Modus jeder Artikel einzeln übermittelt wird und damit auch korrekt pro Artikel der
+jeweilige Brutto- und Nettopreis, sowie der anfallende Steuerbetrag und ein Steuerkennzeichen (mit Hilfe des optionalen
+``HREF``-Attributs) übermittelt werden, ist dies im "pro Zahlvorgang"-Modus nicht möglich.
+
+Stattdessen übermittelt pretix nur einen Betrag für den gesamten Warenkorb: Bruttopreis == Nettopreis. Der Steuerbetrag
+wird hierbei als 0 übermittelt.
+
+Die Angabe einer Haushaltsstelle und Objektnummer, sowie optional der ``HREF``-Kontierungsinformationen ist jedoch
+weiterhin notwendig - allerdings nicht mehr individuell für jeden Artikel/jede Position sondern nur für die gesamte
+Bestellung. Diese Daten sind direkt in den ePayBL-Einstellungen der Veranstaltung unter Einstellungen -> Zahlung ->
+ePayBL vorzunehmen
+
+In der Praxis bedeutet dies, dass in einem angeschlossenen Haushaltssystem nicht nachvollzogen kann, welche Positionen
+konkret erworben und bezahlt wurden - stattdessen kann nur der Fakt, dass etwas verkauft wurde erfasst werden.
+
+Je nach Aufbau und Vorgaben der Finanzbuchhaltung kann dies jedoch ausreichend sein - wenn bspw. eine Ferienfahrt
+angeboten wird und seitens der Haushaltssysteme nicht erfasst werden muss, wie viel vom Gesamtbetrag einer Bestellung
+auf die Ferienfahrt an sich, auf einen Zubringerbus und einen Satz Bettwäsche entfallen ist, sondern (vereinfacht
+gesagt) es ausreichend ist, dass "Eine Summe X für die Haushaltsstelle/Objektnummer geflossen ist".
+
+Dieser Modus der Kontierung bietet Ihnen auch als Vorteil gegenüber dem vorhergehenden an, dass die Bestellungen der
+Kunden jederzeit erweitert und verändert werden können - auch wenn die Ursprungsbestellung schon bezahlt wurde und nur
+noch eine Differenz gezahlt wird.
+
+
+Einschränkungen
+---------------
+
+Zum aktuellen Zeitpunkt erlaubt die pretix-Anbindung an ePayBL nicht das durchführen von Erstattungen von bereits
+geleisteten Zahlungen. Der Prozess hierfür unterscheidet sich von Behörde zu Behörde und muss daher händisch
+durchgeführt werden.

+GetYourGuide
+============
+
+.. note::
+
+    The GetYourGuide integration is currently in Beta. Please contact support@pretix.eu to enable the integration
+    for your pretix.eu organizer account.
+
+Introduction
+------------
+Using third party aggregators, such als GetYourGuide, event organizers can sell tickets to their events not only on
+their own ticket-shop but also on the aggregator's portal. While this service is not for free, it allows event
+organizers to reacher a larger audience that would otherwise not have found their way into the organizers webshop.
+
+Using pretix' integration with GetYourGuide, event organizers can profit from an additional sales and revenue channel,
+while keeping the effort for setting up and maintaining multiple ticket shops to a minimum.
+
+Preparing your organizer account
+--------------------------------
+The first step in enabling the GetYourGuide integration, is to setup a corresponding Sales Channel, which will be used
+to properly attribute the sales generated. This needs to be done only once per organizer account.
+
+To do so, log into the pretix backend, select ``Organizers`` from the navigation and then the organizer in question.
+Extending the ``Settings``-menu, find the ``Sales channels`` configuration and click the ``Add a new channel`` button.
+
+On the following page, you will be able to select ``GetYourGuide`` as the sales channel type and give it a custom name.
+
+Preparing your event
+--------------------
+In order to now sell your events on GetYourGuide, you will need to configure each event in question.
+
+1. Enabling the plugin
+    Within your event, extend the ``Settings`` menu and navigate to ``Plugins``. Activate the plugin in the
+    ``Integrations`` tab.
+
+2. Sell the event on the sales channel
+    Pick the sales channel or channels, on which you would like to sell your event by navigating to the event's general
+    settings page using the ``Sell on all sales channels`` or ``Restrict to specific sales channels`` checkboxes.
+
+3. Configure one or more products to be sold on GetYourGuide
+    Either create a new or edit an existing product, that you would like to sell on GetYourGuide. To do so, you will
+    need to have checked the ``Sell on all sales channels`` or appropriate ``Restrict to specific sales channels``
+    checkbox of the product within it's ``Availability`` tab.
+    In addition, you will also need to set the GetYourGuide equivalent ticket category in the product's accordingly
+    named settings tab. Within your event, there can be only one product per ticket category. Depending on your further
+    configuration, you must at least select one product to be in the ``Adult`` or ``Group`` category.
+
+4. Configuring the GetYourGuide-plugin
+    Once you have configured one or more products to be eligible to be sold on GetYourGuide, you'll need to configure a
+    few basic settings within the event (``Settings`` --> ``GetYourGuide``). The most important settings can be found
+    the in the ``Configuration`` tab, such as the location of the event on sale.
+
+Ticket Categories
+-----------------
+While pretix only uses the ticket category term loosely to group together multiple products for nicer display,
+GetYourGuide is relying on the ticket categories to price the tickets.
+
+First of all, you need to make the decision on how you are planning on selling your tickets on GetYourGuide - in most
+cases, this will reflect your current sales strategy within your pretix shop.
+
+- Individual tickets
+    Every single person attending will need to purchase their own ticket. A family of two adults and two
+    children will have to purchase and pay for a total of 4 tickets.
+    In this case, you will need to offer *at least* a ticket of the ``Adult`` type, but may offer any other ticket
+    category type (Child, Youth, Senior, ...) in addition. But you cannot offer a ``Group`` ticket.
+
+- Group tickets
+    Two groups, consisting of 10 and 20 participants respectively, won't need to purchase a total of 30 tickets, but
+    rather two group tickets. It is up to you to configure the group size limits within the GetYourGuide-settings of your
+    product.
+    Choosing this option, you cannot offer any other ticket categories besides ``Group``.
+
+Setting up event dates and quotas
+---------------------------------
+Of course, in addition to creating products, you will also need to add them to a quota for them to be available for
+sale. The process for doing this is the very same as for any regular event or event series.
+
+.. note::
+
+    When selling individual tickets through GetYourGuide, you will not be able to offer differing quantities for
+    individual ticket categories.
+
+For this reason, we recommend to place all GetYourGuide-eligible products into the same quota. Should you however opt
+to create multiple quotas which create an imbalance, pretix will report only the available number of tickets for the
+lowest relevant quota.
+
+Connecting your event to GetYourGuide
+-------------------------------------
+Once you have set up your event and products and performed all necessary configuration, you may want to use the
+Analyzer-feature of our GetYourGuide-plugin (``Settings`` -> ``GetYourGuide`` -> tab ``Analyzer``).
+
+The Analyzer should not display any blocking error messages and at least one event date that is ready for publishing on
+the GetYourGuide platform.
+
+At this point, you will need to setup your event (called ``product`` in the GetYourGuide universe) on their
+`Supplier Portal`_ and connect it with your pretix shop. To do so, please follow the
+`Connecting a new product to your Reservation System`_ on the GetYourGuide Supply Partner Help Center.
+
+Select ``pretix.eu`` as your reservation system; the required ``product ID`` can be found in the ``Configuration`` tab
+of the GetYourGuide plugin settings page.
+
+From this point on, GetYourGuide will automatically import the availabilities and products and offer them for sale.

+KulturPass
+=========
+
+.. note::
+
+    Since the KulturPass is specific to event organizers within Germany, the following page is also  only provided in
+    German. Should you require assistance with the KulturPass and do not speak this language, please feel free reach
+    out to support@pretix.eu.
+
+
+Einführung
+----------
+Der `KulturPass`_ ist ein Angebot der Bundesregierung für alle, die im laufenden Jahr ihren 18. Geburtstag feiern.
+Sie erhalten ab ihrem 18. Geburtstag ein Budget von 200 Euro, das sie für Eintrittskarten, Bücher, CDs, Platten und
+vieles andere einsetzen können. So wird Kultur vor Ort noch einfacher erlebbar. Gleichzeitig stärkt das die Nachfrage
+bei den Anbietenden.
+
+Da pretix ein Ticketing-System ist, stellen wir ausschließlich einen automatisierten Prozess für den Verkauf von
+Eintrittskarten über den KulturPass-Marktplatz bereit.
+
+
+Registrierung und Einrichtung
+-----------------------------
+Um als Unternehmen oder Kultureinrichtung Angebote auf dem KulturPass-Marktplatz anbieten zu können, ist zunächst eine
+Registerung und die Einrichtung eines "Shops" sowie der dazugehörigen Angebote notwendig.
+
+1. Registrierung
+    Registrieren Sie sich zunächst unter https://www.kulturpass.de/anbietende/layer als Anbieter. Im Zuge der
+    Registrierung beantworten Sie einige Fragen zu Ihrem Unternehmen/Ihrer Kultureinrichtung, hinterlegen Ihre
+    E-Mail-Adresse und beantworten Fragen zu Ihren Angebotsformen sowie Finanzierung Ihrer Einrichtung.
+
+2. Anlegen eines KulturPass Shops
+    Nach Ihrer Registrierung müssen Sie der Weitergabe Ihrer Daten an die technische Platform hinter dem KulturPass,
+    Mirakl, zustimmen. Hier benennen Sie auch Ihren Shop.
+
+3. Identifizierung mit ELSTER-Zertifikat
+    Als nächsten Schritt müssen Sie Ihr Unternehmen oder Ihre Einrichtung mit Hilfe eines sog. ELSTER-Zertifikates
+    identifizieren. Dieses Zertifikat nutzen Sie auch bereits jetzt schon, wenn Sie auf elektronischem Wege mit der
+    Finanzverwaltung kommunizieren.
+
+4. Ersteinrichtung in pretix
+    Hinterlegen Sie nun die ID-Nummer Ihres KulturPass Marktplatz-Shops sowie einen API-Key in den
+    `Einstellungen Ihres Veranstalterkontos`_ (Veranstalter-Konto -> Einstellungen -> KulturPass). Diese Daten müssen
+    Sie nur einmalig für alle Ihre Veranstaltungen angeben.
+
+    Im `KulturPass-Backend`_ finden Sie die benötigten Informationen indem Sie auf das Benutzer-Symbol in der oberen,
+    rechten Ecke klicken, "Profil" und dann "API Schlüssel" auswählen bzw. indem Sie auf "Einstellungen" in der
+    Navigation links und dann "Shop" auswählen.
+
+.. note::
+
+    Zu jedem Zeitpunkt kann nur ein Hintergrundsystem mit dem KulturPass-System verbunden sein. Werden
+    unterschiedliche Systeme oder gar mehrere pretix-Veranstalterkonten mit dem gleichen KulturPass-System verbunden,
+    können keine Bestellungen mehr verarbeitet werden und Angebote nicht automatisiert an den KulturPass-Marktplatz
+    übermittelt werden. Eingehende Bestellungen von Jugendlichen werden in diesem Fall automatisch abgelehnt, da diese
+    nicht eindeutig zugeordnet werden können. Ebenso überschreibt die Bereitstellung der Angebote eines Systems die
+    Angebote eines anderen Systems.
+
+    Wenn Sie mehrere Systeme haben, die den KulturPass-Marktplatz bedienen sollen, wenden Sie sich bitte an den
+    KulturPass-Support, um sich einen weiteren Shop einrichten zu lassen.
+
+5. Aktivierung der KulturPass-Erweiterungen
+    Alle Veranstaltungen, die Sie über den KulturPass anbieten möchten, benötigen die `KulturPass-Erweiterung`_.
+    Aktivieren Sie diese bitte in jeder relevanten Veranstaltung über Einstellungen -> Erweiterungen -> Tab
+    "Integrationen" -> KulturPass.
+
+6. Konfiguration der Artikel
+    Nachdem die KulturPass-Erweiterung aktiviert wurde, müssen Sie sich entscheiden, welche Produkte Sie über den
+    KulturPass-Marktplatz anbieten möchten. In der Bearbeitungs-Ansicht des jeweiligen Produktes finden Sie hierzu im
+    Tab "Zusätzliche Einstellungen" eine Checkbox "Das Produkt kann mit dem KulturPass erworben werden".
+
+.. note::
+
+    Die Eigenschaft, dass ein Produkt durch den KulturPass-Marktplatz erworben werden kann, kann für beliebig viele
+    Produkte aktiviert werden. Auf Grund der Funktionsweise des KulturPasses sollten Sie jedoch gerade bei vielen
+    Artikeln mit unterschiedlich hohen Preisen darauf achten, dass die Preisspanne nicht zu hoch ausfällt.
+
+    Aktivieren Sie die Option für drei Produkte für 1, 10 und 100 Euro, so wird Ihr Angebot im KulturPass-Marktplatz
+    für 100 Euro gelistet werden. Dies bedeutet im Umkehrschluss auch, dass das KulturPass-Guthaben eines Jugendlichen
+    auch mindestens 100 Euro betragen muss, damit er Ihr Angebot in Anspruch nehmen kann - auch wenn die betroffene
+    Person lediglich das 1 Euro-Angebot wahrnehmen möchte. Erst mit dem 100 Euro KulturPass-Einlösecode wählt die
+    kaufende Person in Ihrem pretix-Shop aus, welches Produkt erworben werden soll. Ein Restguthaben wird nach dem Kauf
+    automatisch zurückerstattet und dem KulturPass-Konto wieder gutgeschrieben.
+
+7. Konfiguration des Marktplatz-Eintrages
+    Je nach dem, ob es sich bei Ihrer Veranstaltung um eine Einzelveranstaltung oder eine Veranstaltungsreihe handelt,
+    müssen Sie die folgende Einstellung einmalig oder pro Veranstaltungstermin vornehmen.
+
+    Einzelveranstaltungen konfigurieren Sie über den Menüpunkt "KulturPass" in den Einstellungen Ihrer Veranstaltung;
+    Veranstaltungsreihen beim Anlegen oder Editieren eines jeden einzelnen Termins am Ende der Seite.
+
+    Um eine Veranstaltung oder einen Veranstaltungstermin im KulturPass-Marktplatz anzubieten, aktivieren Sie zunächst
+    die Option "Diese Veranstaltung via KulturPass anbieten". Geben Sie im folgenden die benötigten Informationen an.
+
+    Bitte beachten Sie, dass Sie bei den Angaben präzise Titel und Beschreibungen verwenden, da der KulturPass-
+    Marktplatz ausschließlich die Informationen aus diesem Bereich verwendet. Etwaige andere Informationen die Sie
+    bspw. in den "Text auf Startseite"-Felder eingeben haben, erreichen das KulturPass-System nicht.
+
+.. note::
+
+    Gerade bei Veranstaltungsreihen nutzen viele pretix-Veranstalter gerne verkürzte Termin-Namen. Ein Schwimmbad würde
+    beispielsweise Ihre Veranstaltungsreihe "Freibad Musterstadt" und die einzelnen Termine nur "Schwimmen" nennen.
+
+    Während dies im pretix-Shop in einem gemeinsamen Kontext wunderbar funktioniert, würde eine Veranstaltung mit dem
+    Titel "Schwimmen" im KulturPass-Marktplatz Informationen vermissen lassen. Wählen Sie daher für das Eingabefeld
+    "Veranstaltungstitel" in der KulturPass-Konfiguration einen sprechenden Wert.
+
+8. Übermittlung der Angebote
+    Sobald Sie Ihre ersten Veranstaltungen konfiguriert und live geschaltet haben, übermittelt pretix automatisch in
+    regelmäßigen Abständen alle von Ihnen angebotenen Veranstaltungen an das KulturPass System (Mirakl). Bitte beachten
+    Sie jedoch, dass der Import der Produkte und Angebote einige Zeit in Anspruch nehmen kann. Zum einen müssen
+    Angebote initial händisch von den Betreibern der KulturPass-Platform freigegeben werden, zum anderen muss auch eine
+    Synchronisation zwischen dem Hintergrundsystem und der KulturPass-App erfolgen. Auf die Dauer dieser Prozesse hat
+    pretix keinen Einfluss.
+
+9. Freischalten des Marktplatz-Shops
+    Nachdem pretix erstmalig Angebote an das KulturPass-System übermittelt hat, müssen Sie Ihren Shop KulturPass-Shop
+    einmalig freischalten. Loggen Sie sich hierzu in das `KulturPass-Backend`_ ein.
+
+
+Verwalten von KulturPass-Bestellungen
+-------------------------------------
+Durch die Nutzung der pretix-Integration mit dem KulturPass-System müssen Sie sich - bis auf die Kennzeichnung von
+Produkten, die per KulturPass erworben werden dürfen, sowie die Bereitstellung von Veranstaltungs-Informationen für den
+KulturPass-Marktplatz - um nichts kümmern: pretix übermittelt automatisch Ihre Veranstaltungen, wickelt die Einlösung
+der Tickets ab und führt die Abrechnung mit dem Hintergrund-System durch.
+
+Für Ihre Kunden verhält sich der KulturPass wie eine Zahlungsmethode im Bestellprozess und wird dort neben Ihren
+anderen Zahlungsmethoden mit angeboten.
+
+Die Gelder für mit dem KulturPass bezahlte Tickets erhalten Sie in Form einer Sammel-Überweisung von der Stiftung
+Digitale Chancen auf das von Ihnen beim KulturPass Onboarding angegeben Bankkonto.
+
+In Ihrem `KulturPass-Backend`_ können Sie über den Menüpunkt "Buchhaltung" Ihre bereits erfolgten und kommenden
+Auszahlungen betrachten.
+
+.. note::
+
+    Es ist von äußerster Wichtigkeit, dass Sie weder die eingehenden Bestellungen noch die Produkte und Angebote im
+    KulturPass-Backend händisch bearbeiten - auch wenn dies möglich wäre.
+
+    Bei händischen Änderungen riskieren Sie, dass die Datenbasis zwischen pretix und dem KulturPass-System divergiert
+    und es zu fehlerhaften Buchungen kommt. Wann immer möglich, sollten Sie Korrekturbuchungen und Änderungen
+    ausschließlich über pretix vornehmen.
+
+    Sollte eine händische Änderung/Korrektur notwendig werden, wenden Sie sich bitte an den pretix-Support, damit wir
+    die Auswirkungen evaluieren und vorab mit Ihnen besprechen können!
+
+Erstattungen für Stornos und Absagen können Sie wie gehabt über das pretix-Backend vornehmen. Der jeweilige Betrag wird
+dem KulturPass-Konto dann automatisch gutgeschrieben.
+
+Da nach Ausgabe eines KulturPass Einlöse-Codes dieser vom Kunden jederzeit oder vom System bei
+Nicht-(Komplett)Einlösung binnen 48 Stunden storniert werden kann, kann das im KulturPass-Backend angezeigte,
+auszuzahlende Guthaben fluktuieren. Da in der Regel Auszahlungen frühestens 48 Stunden nach der Aufgabe einer
+KulturPass-Bestellungen erfolgen, sollte Ihr Guthaben in der Regel nicht ins Negative gehen.
+
+Ablauf für Kunden
+-----------------
+Ihre Kunden erhalten - nachdem sie sich ein eigenes Konto in der KulturPass-App angelegt und sich mit ihrem
+elektronischen Personalausweis identifiziert haben - ein Guthaben von 200 Euro, welches für Leistungen aus dem
+KulturPass-Marktplatz eingelöst werden kann.
+
+Im Falle von Veranstaltungen, die per pretix verkauft werden, wählt der Kunde ein Angebot aus und erhält im folgenden
+binnen kurzer Zeit (ca. 10-20 Minuten) einen Code und einen Link, um diesen einzulösen. Der Link bringt den Kunden direkt auf die Seite der
+betreffenden pretix-Veranstaltung. Hier wird der Kunde darauf hingewiesen, für welche Produkte der Code genutzt werden
+kann.
+
+Im Bezahlschritt des Verkaufsprozesses wird dem Kunden vorgeschlagen, seinen KulturPass Einlösecode nun zu nutzen, um
+die gewünschte Leistung zu erhalten.
+
+Wurde ein Artikel gewählt, welcher günstiger als der Wert des Einlösecodes war, wird das Restguthaben automatisch auf
+das KulturPass-Konto erstattet.
+
+Wurden hingegen mehrere Artikel in den Warenkorb gelegt, so kann die Differenz mit einem anderen, regulären
+Zahlungsmittel erfolgen.
+
+Einlösecodes, die vom Kunden nicht binnen 48 Stunden eingelöst werden, werden automatisch storniert und dem
+KulturPass-Konto wieder gutgeschrieben. Dieser Mechanismus greift auch, wenn eine Veranstaltung mittlerweile
+ausverkauft ist und daher der Einlösecode nicht mehr Nutzbar ist.

+Presale SAML Authentication
+===========================
+
+The Presale SAML Authentication plugin is an advanced plugin, which most event
+organizers will not need to use. However, for the select few  who do require
+strong customer authentication that cannot be covered by the built-in customer
+account functionality, this plugin allows pretix to connect to a SAML IdP and
+perform authentication and retrieval of user information.
+
+Usage of the plugin is governed by two separate sets of settings: The plugin
+installation, the Service Provider (SP) configuration and the event
+configuration.
+
+Plugin installation and initial configuration
+---------------------------------------------
+
+.. note:: If you are a customer of our hosted `pretix.eu`_ offering, you can
+          skip this section.
+
+The plugin is installed as any other plugin in the pretix ecosystem. As a
+pretix system administrator, please follow the instructions in the the
+:ref:`Administrator documentation <admindocs>`.
+
+Once installed, you will need to assess, if you want (or need) your pretix
+instance to be a single SP for all organizers and events or if every event
+organizer has to provide their own SP.
+
+Take the example of a university which runs pretix under an pretix Enterprise
+agreement. Since they only provide ticketing services to themselves (every
+organizer is still just a different department of the same university), a
+single SP should be enough.
+
+On the other hand, a reseller such as `pretix.eu`_ who services a multitude
+of clients would not work that way. Here, every organizer is a separate
+legal entity and as such will also need to provide their own SP configuration:
+Company A will expect their SP to reflect their company - and not a generalized
+"pretix SP".
+
+Once you have decided on the mode of operation, the :ref:`Configuration file
+<config>` needs to be extended to reflect your choice.
+
+Example::
+
+    [presale-saml]
+    level=global
+
+``level``
+    ``global`` to use only a single, system-wide SP, ``organizer`` for multiple
+    SPs, configured on the organizer-level. Defaults to ``organizer``.
+
+Service Provider configuration
+------------------------------
+
+Global Level
+^^^^^^^^^^^^
+
+.. note:: If you are a customer of our hosted `pretix.eu`_ offering, you can
+          skip this section and follow the instructions on the upcoming
+          Organizer Level settings.
+
+As a user with administrative privileges, please activate them by clicking the
+`Admin Mode` button in the top right hand corner.
+
+You should now see a new menu-item titled `SAML` appear.
+
+Organizer Level
+^^^^^^^^^^^^^^^
+
+Navigate to the organizer settings in the pretix backend. In the navigation
+bar, you will find a menu-item titled `SAML` if your user has the `Can
+change organizer settings` permission.
+
+
+.. note:: If you are a customer of our hosted `pretix.eu`_ offering, the menu
+          will only appear once one of our friendly customer service agents
+          has enabled the Presale SAML Authentication plugin for at least one
+          of your events. Feel free to get in touch with us!
+
+Setting up the SP
+^^^^^^^^^^^^^^^^^
+
+No matter where your SP configuration lives, you will be greeted by a very
+long list of fields of which almost all of them will need to be filled. Please
+don't be discouraged - most of the settings don't need to be decided by yourself
+and/or are already preset with a sensible default setting.
+
+If you are not sure what setting you should choose for any of the fields, you
+should reach out to your IdP operator as they can tell you exactly what the IdP
+expects and - more importantly - supports.
+
+``IdP Metadata URL``
+    Please provide the URL where your IdP outputs its metadata. For most IdPs,
+    this URL is static and the same for all SPs. If you are a member of the
+    DFN-AAI, you can find the meta-data for the `Test-, Basic- and
+    Advanced-Federation`_ on their website. Please do talk with your local
+    IdP operator though, as you might not even need to go through the DFN-AAI
+    and might just use your institutions local IdP which will also host their
+    metadata on a different URL.
+
+    The URL needs to be publicly accessible, as saving the settings form will
+    fail if the IdP metadata cannot be retrieved. pretix will also automatically
+    refresh the IdP metadata on a regular basis.
+
+``SP Entity Id``
+    By default, we recommend that you use the system-proposed metadata-URL as
+    the Entity Id of your SP. However, if so desired or required by your IdP,
+    you can also set any other, arbitrary URL as the SP Entity Id.
+
+``SP Name / SP Decription``
+    Most IdP will display the name and description of your SP to the users
+    during authentication. The description field can be used to explain to the
+    users how their data is being used.
+
+``SP X.509 Certificate / SP X.509 Private Key``
+    Your SP needs a certificate and a private key for said certificate. Please
+    coordinate with your IdP, if you are supposed to generate these yourself or
+    if they are provided to you.
+
+``SP X.509 New Certificate``
+    As certificates have an expiry date, they need to be renewed on a regular
+    basis. In order to facilitate the rollover from the expiring to the new
+    certificate, you can provide the new certificate already before the expiration
+    of the existing one. That way, the system will automatically use the correct
+    one. Once the old certificate has expired and is not used anymore at all,
+    you can move the new certificate into the slot of the normal certificate and
+    keep the new slot empty for your next renewal process.
+
+``Requested Attributes``
+    An IdP can hold a variety of attributes of an authenticating user. While
+    your IdP will dictate which of the available attributes your SP can consume
+    in theory, you will still need to define exactly which attributes the SP
+    should request.
+
+    The notation is a JSON list of objects with 5 attributes each:
+
+      * ``attributeValue``: Can be defaulted to ``[]``.
+      * ``friendlyName``: String used in the upcoming event-level settings to
+        retrieve the attributes data.
+      * ``isRequired``: Boolean indicating whether the IdP must enforce the
+        transmission of this attribute. In most cases, ``true`` is the best
+        choice.
+      * ``name``: String of the internal, technical name of the requested
+        attribute. Often starting with ``urn:mace:dir:attribute-def:``,
+        ``urn:oid:`` or ``http://``/``https://``.
+      * ``nameFormat``: String describing the type of ``name`` that has been
+        set in the previous section. Often starting with
+        ``urn:mace:shibboleth:1.0:`` or ``urn:oasis:names:tc:SAML:2.0:``.
+
+    Your IdP can provide you with a list of available attributes. See below
+    for a sample configuration in an academic context.
+
+    Note, that you can have multiple attributes with the same ``friendlyName``
+    but different ``name``s. This is often used in systems, where the same
+    information (for example a persons name) is saved in different fields -
+    for example because one institution is returning SAML 1.0 and other
+    institutions are returning SAML 2.0 style attributes. Typically, this only
+    occurs in mix environments like the DFN-AAI with a large number of
+    participants. If you are only using your own institutions IdP and not
+    authenticating anyone outside of your realm, this should not be a common
+    sight.
+
+``Encrypt/Sign/Require ...``
+    Does what is says on the box - please inquire with your IdP for the
+    necessary settings. Most settings can be turned on as they increase security,
+    however some IdPs might stumble over some of them.
+
+``Signature / Digest Algorithm``
+    Please chose appropriate algorithms, that both pretix/your SP and the IdP
+    can communicate with. A common source of issues when connecting to a
+    Shibboleth-based IdP is the Digest Algorithm: pretix does not support
+    ``http://www.w3.org/2009/xmlenc11#rsa-oaep`` and authentication will fail
+    if the IdP enforces this.
+
+``Technical/Support Contacts``
+    Those contacts are encoded into the SPs public meta data and might be
+    displayed to users having trouble authenticating. It is recommended to
+    provide a dedicated point of contact for technical issues, as those will
+    be the ones to change the configuration for the SP.
+
+Event / Authentication configuration
+------------------------------------
+
+Basic settings
+^^^^^^^^^^^^^^
+
+Once the plugin has been enabled for a pretix event using the Plugins-menu from
+the event's settings, a new *SAML* menu item will show up.
+
+On this page, the actual authentication can be configured.
+
+``Checkout Explanation``
+    Since most users probably won't be familiar with why they have to authenticate
+    to buy a ticket, you can provide them a small blurb here. Markdown is supported.
+
+``Attribute RegEx``
+    By default, any successful authentication with the IdP will allow the user to
+    proceed with their purchase. Should the allowed audience needed to be restricted
+    further, a set of regular Expressions can be used to do this.
+
+    An Attribute RegEx of ``{}`` will allow any authenticated user to pass.
+
+    A RegEx of ``{ "affiliation": "^(employee@pretix.eu|staff@pretix.eu)$" }`` will
+    only allow user to pass which have the ``affiliation`` attribute and whose
+    attribute either matches ``employee@pretix.eu`` or ``staff@pretix.eu``.
+
+    Please make sure that the attribute you are querying is also requested from the
+    IdP in the first place - for a quick check you can have a look at the top of
+    the page where all currently configured attributes are listed.
+
+``RegEx Fail Explanation``
+    Only used in conjunction with the above Attribute RegEx. Should the user not
+    pass the restrictions imposed by the regular expression, the user is shown
+    this error-message.
+
+    If you are - for example in an university context - restricting access to
+    students only, you might want to explain here that Employees are not allowed
+    to book tickets.
+
+``Ticket Secret SAML Attribute``
+    In very specific instances, it might be desirable that the ticket-secret is
+    not the randomly one generated by pretix but rather based on one of the
+    users attributes - for example their unique ID or access card number.
+
+    To achieve this, the name of a SAML-attribute can be specified here.
+
+    It is however necessary to note, that even with this setting in use,
+    ticket-secrets need to be unique. This is why when this setting is enabled,
+    the default, pretix-generated ticket-secret is prefixed with the attributes
+    value.
+
+    Example: A users ``cardid`` attribute has the value of ``01189998819991197253``.
+    The default random ticket secret would have been
+    ``yczygpw9877akz2xwdhtdyvdqwkv7npj``. The resulting new secret will now be
+    ``01189998819991197253_yczygpw9877akz2xwdhtdyvdqwkv7npj``.
+
+    That way, the ticket secret is still unique, but when checking into an event,
+    the user can easily be searched and found using their identifier.
+
+IdP-provided E-Mail addresses, names
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, pretix will only authenticate the user and not process the received
+data any further.
+
+However, there are a few exceptions to this rule.
+
+There are a few `magic` attributes that pretix will use to automatically populate
+the corresponding fields within the checkout process **and lock them out from
+user editing**.
+
+  * ``givenName`` and ``sn``: If both of those attributes are present and pretix
+    is configured to collect the users name, these attributes' values are used
+    for the given and family name respectively.
+  * ``email``: If this attribute is present, the E-Mail-address of the users will
+    be set to the one transmitted through the attributes.
+
+The latter might pose a problem, if the IdP is transmitting an ``email`` attribute
+which does contain a system-level mail address which is only used as an internal
+identifier but not as a real mailbox. In this case, please consider setting the
+``friendlyName`` of the attribute to a different value than ``email`` or removing
+this field from the list of requested attributes altogether.
+
+Saving attributes to questions
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By setting the ``internal identifier`` of a user-defined question to the same name
+as a SAML attribute, pretix will save the value of said attribute into the question.
+
+All the same as in the above section on E-Mail addresses, those fields become
+non-editable by the user.
+
+Please be aware that some specialty question types might not be compatible with
+the SAML attributes due to specific format requirements. If in doubt (or if the
+checkout fails/the information is not properly saved), try setting the question
+type to a simple type like "Text (one line)".
+
+Notes and configuration examples

+
+Requesting skIDentity attributes for electronic identity cards
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This requests the basic ``eIdentifier``, ``IDType``, ``IDIssuer``, and
+``NameID`` from the `skIDentity`_ SAML service, which are available for
+electronic ID cards such as the German ePA/NPA. (Other attributes such as
