+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

+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``).
+
+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``.

+
+Running an export
+-----------------
+
+Since exports often include large data sets, they might take longer than the duration of an HTTP request. Therefore,
+creating an export is a two-step process. First you need to start an export task with one of the following to API
+endpoints:
+
+.. http:post:: /api/v1/organizers/(organizer)/events/(event)/exporters/(identifier)/run/
+
+   Starts an export task. If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to the download URL of the result.
+
+   **Example request**:
+
+   .. sourcecode:: http
+
+      POST /api/v1/organizers/bigevents/events/sampleconf/exporters/orderlist/run/ HTTP/1.1
+      Host: pretix.eu
+      Accept: application/json, text/javascript
+      Content-Type: application/json
+
+      {
+        "_format": "xlsx"
+      }
+
+   **Example response**:
+
+   .. sourcecode:: http
+
+      HTTP/1.1 200 OK
+      Vary: Accept
+      Content-Type: application/json
+
+      {
+        "download": "https://pretix.eu/api/v1/organizers/bigevents/events/sampleconf/orderlist/download/29891ede-196f-4942-9e26-d055a36e98b8/3f279f13-c198-4137-b49b-9b360ce9fcce/"
+      }
+
+   :param organizer: The ``slug`` field of the organizer to fetch
+   :param event: The ``slug`` field of the event to fetch
+   :param identifier: The ``identifier`` field of the exporter to run
+   :statuscode 202: no error
+   :statuscode 400: Invalid input options
+   :statuscode 401: Authentication failure
+   :statuscode 403: The requested organizer/event does not exist **or** you have no permission to view this resource.
+
+.. http:post:: /api/v1/organizers/(organizer)/exporters/(identifier)/run/
+
+   The endpoint for organizer-level exports works just like event-level exports (see above).
+
+
+Downloading the result
+----------------------
+
+When starting an export, you receive a ``url`` for downloading the result. Running a ``GET`` request on that result will
+yield one of the following status codes:
+
+* ``200 OK`` – The export succeeded. The body will be your resulting file. Might be large!
+* ``409 Conflict`` – Your export is still running. The body will be JSON with the structure ``{"status": "running", "percentage": 40}``. ``percentage`` can be ``null`` if it is not known and ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+* ``410 Gone`` – Running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+* ``404 Not Found`` – The export does not exist / is expired.
+
+.. warning::
+
+   Running exports puts a lot of stress on the system, we kindly ask you not to run more than two exports at the same time.

+Organizer settings
+------------------
+
+pretix organizers and events have lots and lots of parameters of different types that are stored in a key-value store on our system.
+Since many of these settings depend on each other in complex ways, we can not give direct access to all of these
+settings through the API. However, we do expose many of the simple and useful flags through the API.
+
+Please note that the available settings flags change between pretix versions, and we do not give a guarantee on backwards-compatibility like with other parts of the API.
+Therefore, we're also not including a list of the options here, but instead recommend to look at the endpoint output
+to see available options. The ``explain=true`` flag enables a verbose mode that provides you with human-readable
+information about the properties.
+
+.. note:: Please note that this is not a complete representation of all organizer settings. You will find more settings
+          in the web interface.
+
+.. warning:: This API is intended for advanced users. Even though we take care to validate your input, you will be
+             able to break your shops using this API by creating situations of conflicting settings. Please take care.
+
+.. versionchanged:: 3.14
+
+   Initial support for settings has been added to the API.
+

+       Settings can be stored at different levels in pretix. If a value is not set on organizer level, a default setting

+Ticket secret generators
+========================
+
+pretix allows you to change the way in which ticket secrets (also known as "ticket codes", "barcodes", …)
+are generated. This affects the value of the QR code in any tickets issued by pretix, regardless of ticket
+format.
+
+.. note:: This is intended for highly advanced use cases, usually when huge numbers of tickets (> 25k per event)
+          are involved. **If you don't know whether you need this, you probably don't.**
+
+Default: Random secrets
+-----------------------
+
+By default, pretix generates a random code for every ticket, consisting of 32 lower case characters and
+numbers. The characters ``oO1il`` are avoided to reduce confusion when ticket codes are printed and need to
+be typed in manually.
+
+Choosing random codes has a number of advantages:
+
+* Ticket codes are short, which makes QR codes easier to scan. At the same time, it is absolutely impossible to
+  guess or forge a valid ticket code.
+
+* The code does not need to change if the ticket changes. For example, if an attendee is re-booked to a
+  different product or date, they can keep their ticket and it is just mapped to the new product in the
+  database.
+
+This approach works really well for 99 % or events running with pretix.
+The big caveat is that the scanner needs to access a database of all ticket codes in order to know whether a ticket
+code is valid and what kind of ticket it represents.
+
+When scanning online this is no problem at all, since the pretix server always has such a database. In case your local
+internet connection is interrupted or the pretix server goes down, though, there needs to be a database locally on the
+scanner.
+
+Therefore, our pretixSCAN apps by default download the database of all valid tickets onto the device itself. This makes
+it possible to seamlessly switch into offline mode when the connection is lost and continue scanning with the maximum
+possible feature set.
+
+There are a few situations in which this approach is not ideal:
+
+* When running a single event with 25k or more valid tickets, downloading all ticket data onto the scanner may just
+  take too much time and resources.
+
+* When the risk of losing sensible data by losing one of the scanner devices is not acceptable.
+
+* When offline mode needs to be used regularly and newly-purchased tickets need to be valid immediately after purchase,
+  without being able to tolerate a few minutes of delay.
+
+Signature schemes
+-----------------
+
+The alternative approach that is included with pretix is to choose a signature-based ticket code generation scheme.
+These secrets include the most important information that is required for verifying their validity and use modern
+cryptography to make sure they cannot be forged.
+
+Currently, pretix ships with one such scheme ("pretix signature scheme 1") which encodes the product, the product
+variation, and the date (if inside an event series) into the ticket code and signs the code with a `EdDSA`_ signature.
+This allows to verify whether a ticket is allowed to enter without any database or connection to the server, but has
+a few important drawbacks:
+
+* Whenever the product, variation or date of a ticket changes or the ticket is canceled, the ticket code needs to be
+  changed and the old code needs to be put on a revocation list. This revocation list again needs to be downloaded by
+  all scanning devices (but is usually much smaller than the ticket database). The main downside is that the attendee
+  needs to download their new ticket and can no longer use the old one.
+
+* Scanning in offline mode is much more limited, since the scanner has no information about previous usages of the
+  ticket, attendee names, seating information, etc.

+Glossary
+========
+
+This page gives definitions of domain-specific terms that we use a lot inside pretix and that might be used slightly
+differently elsewhere, as well as their official translations to other languages. In some cases, things have a different
+name internally, which is noted with a |:wrench:| symbol. If you only use pretix, you'll never see these, but if you're
+going to develop around pretix, for example connect to pretix through our API, you need to know these as well.

+
+   * - Term
+     - Definition
+   * - | |:gb:| **Organizer**
+       | |:de:| Veranstalter
+     - An organizer represents the entity using pretix, usually the company or institution running one or multiple events.
+       In terms of navigation in the system, organizers are the "middle layer" between the system itself and the specific
+       events.
+       Multiple organizers on the same pretix system are fully separated from each other with very few exceptions.
+   * - | |:gb:| **Event**
+       | |:de:| Veranstaltung
+     - An event is the central entity in pretix that you and your customers interact with all the time. An event
+       represents one **shop** in which things like tickets can be bought. Since the introduction of event series (see
+       below), this might include multiple events in the real world.
+
+       Every purchase needs to be connected to an event, and most things are completely separate between different
+       events, i.e. most actions and configurations in pretix are done per-event.
+   * - | |:gb:| **Event series**
+       | |:de:| Veranstaltungsreihe
+     - An event series is one of two types of events. Unlike a non-series event, an event series groups together
+       multiple real-world events into one pretix shop. Examples are time-slot-based booking for a museum, a band on
+       tour, a theater group playing the same play multiple times, etc.
+   * - | |:gb:| **Date**
+       | |:de:| Termin
+       | |:wrench:| Subevent
+     - A date represents a single real-world event inside an event series. Dates can differ from each other in name,
+       date, time, location, pricing, capacity, and seating plans, but otherwise share the same configuration.
+   * - | |:gb:| **Product**
+       | |:de:| Produkt
+       | |:wrench:| Item
+     - A product is anything that can be sold, such as a specific type of ticket or merchandise.
+   * - | |:gb:| **Admission product**
+       | |:de:| Zutrittsprodukt
+     - A product is considered an **admission product** if its purchase represents a person being granted access to your
+       event. This applies to most ticketing products, but not e.g. to merchandise.
+   * - | |:gb:| **Variation**
+       | |:de:| Variante
+       | |:wrench:| Item variation
+     - Some products come in multiple variations that can differ in description, price and capacity. Examples would
+       include "Adult" and "Child" in case of a concert ticket, or "S", "M", "L", … in case of a t-shirt product.
+   * - | |:gb:| **Category**
+       | |:de:| Kategorie
+     - Products can be grouped together in categories. This is mostly to organize them cleanly in the frontend if you
+       have lots of them.
+   * - | |:gb:| **Quota**
+       | |:de:| Kontingent
+     - A quota is a capacity pool that defines how many times a product can be sold. A quota can be connected to multiple
+       products, in which case all of them are counted together. This is useful e.g. if you have full-price and reduced
+       tickets and only want to sell a certain number of tickets in total. The same way, multiple quotas can be connected
+       to the same product, in which case the ticket will be available as long as all of them have capacity left.
+   * - | |:gb:| **Add-on product**
+       | |:de:| Zusatzprodukt
+     - An add-on product is a product that is purchased as an upgrade or optional addition to a different product.
+       Examples would be include a conference ticket that optionally allows to buy a public transport ticket for the
+       same day, or a family ticket for 4 persons that allows you to add additional persons at a small cost, or a
+       "two workshops" package that allows you to select two of a larger number of workshops at a discounted price.
+       In all cases, there is a "main product" (the conference ticket, the family ticket) and a number of "add-on products"
+       that can be chosen from.
+   * - | |:gb:| **Bundled product**
+       | |:de:| Enthaltenes Produkt
+     - A bundled product is a product that is automatically put into the cart when another product is purchased. It's
+       similar to an add-on product, except that the customer has no choice between whether it is added or which of a
+       set of product is added.
+   * - | |:gb:| **Question**
+       | |:de:| Frage
+     - A question is a custom field that customers need to fill in when purchasing a specific product.
+   * - | |:gb:| **Voucher**
+       | |:de:| Gutschein
+     - A voucher is a code that can be used for multiple purposes: To grant a discount to specific customers, to only
+       show certain products to certain customers, or to keep a seat open for someone specific even though you are
+       sold out. If a voucher is used to apply a discount, the price of the purchased product is reduced by the
+       discounted amount. Vouchers are connected to a specific event.
+   * - | |:gb:| **Gift card**
+       | |:de:| Geschenkgutschein
+     - A :ref:`gift card <giftcards>` is a coupon representing an exact amount of money that can be used for purchases
+       of any kind. Gift cards can be sold, created manually, or used as a method to refund your customer without paying
+       them back directly.
+       Unlike a voucher, it does not reduce the price of the purchased products when redeemed, but instead works as a
+       payment method to lower the amount that needs to be paid through other methods. Gift cards are specific to an
+       organizer by default but can even by shared between organizers.
+   * - | |:gb:| **Cart**
+       | |:de:| Warenkorb
+     - A cart is a collection of products that are reserved by a customer who is currently completing the checkout
+       process, but has not yet finished it.
+   * - | |:gb:| **Order**
+       | |:de:| Bestellung
+     - An order is a purchase by a client, containing multiple different products. An order goes through various
+       states and can change during its lifetime.
+   * - | |:gb:| **Order code**
+       | |:de:| Bestellnummer
+     - An order code is the unique identifier of an order, usually consisting of 5 numbers and letters.
+   * - | |:gb:| **Order position**
+       | |:de:| Bestellposition
+     - An order position is a single line inside an order, representing the purchase of one specific product. If the
+       product is an admission product, this represents an attendee.
+   * - | |:gb:| **Attendees**
+       | |:de:| Teilnehmende
+     - An attendee is the person designated to use a specific order position to access the event.
+   * - | |:gb:| **Fee**
+       | |:de:| Gebühr
+     - A fee is an additional type of line inside an order that represents a cost that needs to be paid by the customer,
+       but is not related to a specific product. A typical example is a shipping fee.
+   * - | |:gb:| **Invoice** and **Cancellation**
+       | |:de:| Rechnung und Rechnungskorrektur
+     - An invoice refers to a legal document created to document a purchase for tax purposes. Invoices have individual
+       numbers and no longer change after they have been issued. Every invoice is connected to an order, but an order
+       can have multiple invoices: If an order changes, a cancellation document is created for the old invoice and a
+       new invoice is created.
+   * - | |:gb:| **Check-in**
+       | |:de:| Check-in
+     - A check-in is the event of someone being successfully scanned at an entry or exit of the event.
+   * - | |:gb:| **Check-in list**
+       | |:de:| Check-in-Liste
+     - A check-in list is used to configure who can be scanned at a specific entry or exit of the event. Check-in lists
+       are isolated from each other, so by default each ticket is valid once on every check-in list individually. They
+       are therefore often used to represent *parts* of an event, either time-wise (e.g. conference days) or space-wise
+       (e.g. rooms).
+   * - | |:gb:| **Plugin**
+       | |:de:| Erweiterung
+     - A plugin is an optional software module that contains additional functionality and can be turned on and off per
+       event. If you host pretix on your own server, most plugins need to be installed separately.
+   * - | |:gb:| **Tax rule**
+       | |:de:| Steuer-Regel
+     - A tax rule defines how sales taxes are calculated for a product, possibly depending on type and country of the
+       customer.
+   * - | |:gb:| **Ticket**
+       | |:de:| Ticket
+     - A ticket usually refers to the actual file presented to the customer to be used at check-in, i.e. the PDF or
+       Passbook file carrying the QR code. In some cases, "ticket" may also be used to refer to an order position,
+       especially in case of admission products.
+   * - | |:gb:| **Ticket secret**
+       | |:de:| Ticket-Code
+     - The ticket secret (sometimes "ticket code") is what's contained in the QR code on the ticket.
+   * - | |:gb:| **Badge**
+       | |:de:| Badge
+     - A badge refers to the file used as a name tag for an attendee of your event.
+   * - | |:gb:| **User**
+       | |:de:| Benutzer
+     - A user is anyone who can sign into the backend interface of pretix.
+   * - | |:gb:| **Team**
+       | |:de:| Team
+     - A :ref:`team <user-teams>` is a collection of users who are granted some level of access to a set of events.
+   * - | |:gb:| **Device**
+       | |:de:| Gerät
+     - A device is something that talks to pretix but does not run on a server. Usually a device refers to an
+       installation of pretixSCAN, pretixPOS or some compatible third-party app on one of your computing devices.
+   * - | |:gb:| **Gate**
+       | |:de:| Station
+     - A gate is a location at your event where people are being scanned, e.g. an entry or exit door. You can configure
+       gates in pretix to group multiple devices together that are used in the same location, mostly for statistical
+       purposes.
+   * - | |:gb:| **Widget**
+       | |:de:| Widget
+     - The :ref:`widget` is a JavaScript component that can be used to embed the shop of an event or a list of events
+       into a third-party web page.
+   * - | |:gb:| **Sales channel**
+       | |:de:| Verkaufskanal
+     - A sales channel refers to the type in which a purchase arrived in the system, e.g. through pretix' web shop itself,
+       or through other channels like box office or reseller sales.
+   * - | |:gb:| **Box office**
+       | |:de:| Abendkasse
+     - Box office purchases refer to all purchases made in-person from the organizer directly, through a point of sale
+       system like pretixPOS.
+   * - | |:gb:| **Reseller**
+       | |:de:| Vorverkaufsstelle
+     - Resellers are third-party entities offering in-person sales of events to customers.
