+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

+Understanding the life cycle of orders
+======================================
+
+When integrating pretix with other systems, it is important that you understand how orders and related objects
+such as order positions, fees, payments, refunds, and invoices work together, in order to react to their changes
+properly and map them to processes in your system.
+
+Order states
+------------
+
+Generally, an order can be in six states. For compatibility reasons, the ``status`` field only allows four values
+and the two remaining states are modeled through the ``require_approval`` field and the number of positions within
+an order. The states and their allowed changes are shown in the following graph:
+
+.. image:: /images/order_states.png
+
+
+Object types
+------------
+
+Order
+    One order represents one purchase. It's the main object you interact with and bundles all the other objects
+    together. Orders can change in many ways during their lifetime, but will never be deleted (unless ``testmode``
+    is set to ``true``).
+
+Order position
+    An order position represents one product contained in the order. Orders can usually have multiple positions.
+    There might be a parent-child relation between order positions if one position is an add-on to another position.
+    Order positions can change in many ways during their lifetime, and can also be removed or added to an order.
+
+Order fees
+    A fee represents a charge that is not related to a product. Examples include shipping fees, service fees, and
+    cancellation fees.
+    Order fees can change in many ways during their lifetime, and can also be removed or added to an order.
+
+Order payment
+    An order payment represents one payment attempt with a specific payment method and amount. An order can have
+    multiple payments attached.
+    Order payments have their own state diagram. Apart from their state and their meta information (e.g. used
+    credit card, …) they usually don't change. They may be added at any time, but will never be deleted.
+
+Order refund
+    An order payment represents one refund attempt with a specific payment method and amount. An order can have
+    multiple refunds attached.
+    Order refunds have their own state diagram. Apart from their state and their meta information (e.g. used
+    credit card, …) they usually don't change. They may be added at any time, but will never be deleted.
+
+Invoice
+    An invoice represents a legal document stating the contents of an order. While the backend technically allows
+    to update an invoice in some situations, invoices are generally considered immutable. Once they are issued,
+    they no longer change. If the order changes substantially (e.g. prices change), an invoice is canceled through
+    creation of a new invoice with the opposite amount, plus the issuance of a new invoice.
+
+Here's an example of how they all play together:

+Data exporters
+==============

+pretix and it's plugins include a number of data exporters that allow you to bulk download various data from pretix in
+different formats. This page shows you how to use these exporters through the API.
+
+.. versionchanged:: 3.13

+
+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
+

+License FAQ
+===========
+
+.. warning::
+
+   This FAQ tries to explain in simpler terms what the license of the pretix open source project does and does not
+   allow. It is based on our interpretation of the license and is not legal advice. The contents of this page are not
+   legally binding, only the original text of the license in the `license file`_ is legally binding.
+
+How is pretix licensed?
+-----------------------
+
+pretix follows the popular dual licensing model. It is available under the `GNU Affero General Public License 3`_ (AGPL)
+plus some additional terms, as well as under a proprietary license ("pretix Enterprise license") on request.
+
+How can it be AGPL if there are additional terms?
+-------------------------------------------------
+
+Even though it is fairly unknown, the AGPL's section 7 is titled "Additional Terms" and outlines specific conditions
+under which additional terms can be imposed on an AGPL-licensed work. In our case, we add three additional terms.
+
+The first additional term for pretix is an additional **permission**. It allows you to do something that the AGPL would
+generally not allow. As it doesn't restrict your freedoms granted by AGPL, if you don't like it, you can ignore it, and
+if you distribute pretix further, you can remove it.
+
+The second and third additional term for pretix are additional terms that restrict or specify other provisions of the
+license. AGPL specifically requires that these terms can only restrict or specify very specific things and we believe
+our additional terms are in compliance with that and are thus valid and may not be removed.
+
+Why did you choose this license model?
+--------------------------------------
+
+pretix was born in the open source community and we're deeply committed to building the best open source ticketing
+solution in the world. It is important to us that pretix is available with a comprehensive feature set under term that
+are compatible with the `Open Source Definition`_. This enables event organizers from all industries and regions
+to have access to a self-hosted, privacy-friendly and secure option to host their events.
+
+However, developing and maintaining pretix is a lot of work. Between 2014 and 2021, we've received external
+contributions from more than 150 individuals. Not counting translations over 90 % of the development was
+done by staff engineers of rami.io GmbH, the company that started pretix. While we're very happy to receive many more
+contributions in the future, we also want to ensure that we continue to be able to pay people working on pretix
+full-time.
+
+We believe our model creates a good balance between ensuring pretix is available freely as well as protecting our
+business interests. Unlike licenses chosen by other projects recently, such as the Server-Side Public License, our
+choice does not restrict using pretix for any possible use case, it just sets a few rules that you have to play by
+if you do.
+
+What do I need to do if I use pretix unmodified?
+------------------------------------------------
+
+If you use pretix without any modifications or plugins, you can use it for whatever you want, as long as you keep
+all copyright notices (including the link to pretix at the bottom of the site) intact.
+
+You are also allowed to make copies of the unmodified source code and distribute them to others as long as you keep
+all copyright and license information intact.
+
+If you install **plugins**, you must follow the same terms as when using a **modified** version (see below).
+
+What do I need to do if I modify pretix?
+----------------------------------------
+
+If you want to modify pretix, you have the right to do so. However, you need to follow the following rules:
+
+* If you **run it for your own events** (events run by you or your company as well as companies from the same
+  corporate groups) our additional permission allows you to do so **without needing to share your source code
+  modifications** as long as you keep the link to pretix at the bottom of the site intact.
+
+* If you **run it for others**, for example as part of a Software-as-a-Service offering or a managed hosting service
+  you **must** make the source code **including all your modifications and all installed plugins** available under the
+  same license as pretix to every visitor of your site. You need to do so in a prominent place such as a link at the bottom of the
+  site. You also **must** keep the existing link intact.
+  You **may not** add additional restrictions on the result as a whole. You **may** add additional permissions, but
+  only on the parts you added. You **must** make clear which changes you made and you must not give the impression that
+  your modified version is an official version of pretix.
+
+* If you **distribute** the modified version, for example as a source code or software package, you **must** license it
+  under the AGPL license with the same additional terms. You **may not** add additional restrictions on the result as a
+  whole. You **may** add additional permissions, but only on the parts you added. You **must** make clear which changes
+  you made and you must not give the impression that your modified version is an official version of pretix.
+
+Does the AGPL copyleft mechanism extend to plugins?
+---------------------------------------------------
+
+Yes. pretix plugins are tightly integrated with pretix, so when running pretix together with a plugin in the same
+environment they form a `combined work`_ and the copyleft mechanism of AGPL applies.
+
+Can I create proprietary or secret plugins?
+-------------------------------------------
+
+Yes, you can create a proprietary or secret plugin, but it may only ever be **used** in an environment that is covered
+by the additional permission from our license. As soon as the plugin is installed in an installation that is not covered
+by our additional permission (e.g. when it is used in a SaaS environment) or covered by an active pretix Enterprise
+license it **must** be released to the visitors of the site under the same license as pretix (like a modified version
+of pretix).
+
+What licenses can plugins use?
+------------------------------
+
+Technically, you can distribute a plugin under any free or proprietary license as long as it is distributed separately.
+However, once it is either **distributed together with pretix or used in an environment not covered by our
+additional permission** or an active pretix Enterprise license, you **must** release it to all recipients of the
+distribution or all visitors of your site under the same license as pretix (like a modified version of pretix).
+
+If you release a plugin publicly, it is therefore most practical to use a license that is `compatible to AGPL`_.
+This includes most open source licenses such as AGPL, GPL, Apache, 3-clause BSD or MIT.
+
+Note however that when you license a plugin with pure AGPL, it will be incompatible with our additional permission.
+Therefore, if you want to use an AGPL-licensed plugin, you'll need to publish the source code of **all** your plugins
+under AGPL terms **even if you only use it for your own events**. A plugin would add its `own additional permission`_
+to its license to allow combining it with pretix for this use case.
+
+To make things less complicated, if you want to distribute a plugin freely, we therefore recommend distributing the
+plugin under **Apache License 2.0**, like we do for most plugins we distribute as open source.
+
+What do I need to do if I want to contribute my changes back?
+-------------------------------------------------------------
+
+In order to retain the possibility for us to offer pretix in a dual licensing model, we unfortunately need you to sign
+a Contributor License Agreement (CLA) that gives us permission to use your contribution in all present and future
+distributions of pretix. We know the bureaucracy sucks. Sorry.
+
+What if I want to re-use a minor part of pretix in my project?
+--------------------------------------------------------------
+
+This is the main part we dislike about AGPL: If you see a specific thing in pretix that you'd like to use in another
+project, you'll need to distribute your other project under AGPL terms as well which is often not practical.
+
+In this case, feel free to get in touch with us! We're happy to grant you special permission or pull the component
+out into a separately, permissively licensed repository. We already did that with `django-hierarkey`_ and
+`django-i18nfield`_ which have previously been parts of pretix.
+
+What can I use the name "pretix" for?
+-------------------------------------
+
+The name pretix is a registered trademark by rami.io GmbH.
+
+* You **may** use it to **indicate copyright**, such as in the "powered by pretix" or "based on pretix" line, or when
+  indicating that a distribution is based on pretix.
+
+* You **may** use it to **indicate compatibility**, for example you are allowed to name your plugin "<name> for pretix"
+  or you may state that an external service is compatible with pretix.
+
+* You **may not** give the impression that your modified version, plugin or compatible service is official or authorized
+  by rami.io GmbH or pretix unless we specifically allowed you to do so.
+
+* You **may not** use it to name your modified version of pretix. End-users must be able to easily identify whether
+  a version of pretix is distributed by us.
+
+* You **may not** use any variations of the name, such as "MyPretix".
