+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

 Digital content
 ===============

+URL interpolation and JWT authentication
+----------------------------------------
+
+In the simplest case, you can use the digital content module to point users to a specific piece of content on some
+platform after their ticket purchase, or show them an embedded video or live stream. However, the full power of the
+module can be utilized by passing additional information to the target system to automatically authenticate the user
+or pre-fill some fields with their data. For example, you could use an URL like this::
+
+    https://webinars.example.com/join?as={attendee_name}&userid={order_code}-{positionid}
+
+While this is already useful, it does not provide much security – anyone could guess a valid combination for that URL.
+Therefore, the module allows you to pass information as a `JSON Web Token`_, which isn't encrypted, but signed with a
+shared secret such that nobody can create their own tokens or modify the contents. To use a token, set up a URL like this::
+
+    https://webinars.example.com/join?with_token={token}
+
+Additionally, you will need to set a JWT secret and a token template, either through the pretix interface or through the
+API (see below). pretix currently only supports tokens signed with ``HMAC-SHA256`` (``HS256``). Your token template can contain
+whatever JSON you'd like to pass on based on the same variables, for example::
+
+    {
+        "iss": "pretix.eu",
+        "aud": "webinars.example.com",
+        "user": {
+            "id": "{order_code}-{positionid}",
+            "product": "{product_id}",
+            "variation": "{variation_id}",
+            "name": "{attendee_name}"
+        }
+    }
+
+Variables can only be used in strings inside the JSON structure.
+pretix will automatically add an ``iat`` claim with the current timestamp and an ``exp`` claim with an expiration timestamp
+based on your configuration.

+Use case: Time slots
+====================
+
+A more advanced use case of pretix is using pretix for time-slot-based access to an area with a limited visitor
+capacity, such as a museum or other attraction. This guide will show you the quickest way to set up such an event
+with pretix.
+
+First of all, when creating your event, you need to select that your event represents an "event series":
+
+
+.. thumbnail:: ../../../screens/event/create_step1.png
+   :align: center
+   :class: screenshot
+
+You can click :ref:`here <subevents>` for a more general description of event series with pretix, but everything you
+need to know is in this chapter as well.
+
+General event setup
+-------------------
+
+Before you go further, set up your products that you want to sell for each time slot, such as different types of entry.
+
+Creating slots
+--------------
+
+To create the time slots, you need to create a number of "dates" in the event series. Select "Dates" in the navigation
+menu on the left side and click "Create many new dates". Then, first enter the pattern of your opening days. In the
+example, the museum is open week Tuesday to Sunday. We recommend to create the slots for a few weeks at a time, but not
+e.g. for a full year, since it will be more complicated to change things later.
+
+.. thumbnail:: ../../../screens/event/timeslots_create.png
+   :align: center
+   :class: screenshot
+
+Then, scroll to the times section and create your time slots. You can do any interval you like. If you have different
+opening times on different week days, you will need to go through the creation process multiple times.
+
+.. thumbnail:: ../../../screens/event/timeslots_create_2.png
+   :align: center
+   :class: screenshot
+
+Scroll further down and create one or multiple quotas that define how many people can book a ticket for that time slot.
+In this example, 50 people in total are allowed to enter within every slot:
+
+.. thumbnail:: ../../../screens/event/timeslots_create_3.png
+   :align: center
+   :class: screenshot
+
+Do **not** create a check-in list at this point. We will deal with this further below in the guide.
+Now, press "Save" to create your slots.
+
+.. warning:: If you create a lot of time slots at once, the server might need a few minutes to create them all in our
+             system. If you receive an error page because it took too long, please do not try again immediately but wait
+             for a few minutes. Most likely, the slots will be created successfully even though you saw an error.
+
+Event settings
+--------------
+
+We recommend that you navigate to "Settings" > "General" > "Display" and set the settings "Default overview style"
+to "Week calendar":
+
+.. thumbnail:: ../../../screens/event/timeslots_settings_1.png
+   :align: center
+   :class: screenshot
+
+Now, your ticket shop should give users a nice weekly overview over all time slots and their availability:
+
+.. thumbnail:: ../../../screens/event/timeslots_presale.png
+   :align: center
+   :class: screenshot
+
+Check-in
+--------
+
+If you want to scan people at the entrance of your event and only admit them at their designated time, we recommend
+the following setup: Go to "Check-in" in the main navigation on the left and create a new check-in list. Give it a name
+and do *not* choose a specific data. We will use one check-in list for all dates. Then, go to the "Advanced" tab at
+the top and set up two restrictions to make sure people can only get in during the time slot they registered for.
+You can create the rules exactly like shown in the following screenshot:
+
+.. thumbnail:: ../../../screens/event/timeslots_checkinlists.png
+   :align: center
+   :class: screenshot
+
+If you want, you can enter a tolerance of e.g. "10" if you want to be a little bit more relaxed and admit people up to
+10 minutes before or after their time slot.
+
+Now, download our `Android or Desktop app`_ and register it to your account. The app will ask you to select one the
+time slots, but it does not matter, you can select any one of them and then select your newly created check-in list.
+That's it, you're good to go!

+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.

-How can I revert a check-in?
----------------------------
-
-Neither our apps nor our web interface can currently undo the check-in of a tickets. We know that this is
-inconvenient for some of you, but we have a good reason for it:
-
-Our Desktop and Android apps both support an asynchronous mode in which they can scan tickets while staying
-independent of their internet connection. When scanning with multiple devices, it can of course happen that two
-devices scan the same ticket without knowing of the other scan. As soon as one of the devices regains connectivity, it
-will upload its activity and the server marks the ticket as checked in -- regardless of the order in which the two
-scans were made and uploaded (which could be two different orders).
-
-If we'd provide a "check out" feature, it would not only be used to fix an accidental scan, but scan at entry and
-exit to count the current number of people inside etc. In this case, the order of operations matters very much for them
-to make sense and provide useful results. This makes implementing an asynchronous mode much more complicated.
-
-In this trade off, we chose offline-capabilities over the check out feature. We plan on solving this problem in the
-future, but we're not there yet.
-
-If you're just *testing* the check-in capabilities and want to clean out everything for the real process, you can just
-delete and re-create the check-in list.

+
+This page gives definitions of domain-specific terms that we use a lot inside pretix and that might be used slightly

+   * - 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**

+   * - | |: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.
