+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);
+    CREATE INDEX CONCURRENTLY pretix_addidx_event_name
+        ON pretixbase_event

+    CREATE INDEX CONCURRENTLY pretix_addidx_order_code
+        ON pretixbase_order
+        USING gin (upper("code") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_voucher_code
+        ON pretixbase_voucher
+        USING gin (upper("code") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_invoice_nu1
+        ON "pretixbase_invoice" (UPPER("invoice_no"));
+    CREATE INDEX CONCURRENTLY pretix_addidx_invoice_nu2
+        ON "pretixbase_invoice" (UPPER("full_invoice_no"));

+    CREATE INDEX CONCURRENTLY pretix_addidx_organizer_slug
+        ON pretixbase_organizer
+        USING gin (upper("slug") gin_trgm_ops);

+        ON pretixbase_order
+        USING gin (upper("email") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_order_comment

+    CREATE INDEX CONCURRENTLY pretix_addidx_orderpos_name
+        ON pretixbase_orderposition
+        USING gin (upper("attendee_name_cached") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_orderpos_scret
+        ON pretixbase_orderposition
+        USING gin (upper("secret") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_orderpos_email

+        ON pretixbase_invoiceaddress
+        USING gin (upper("name_cached") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_ia_company
+        ON pretixbase_invoiceaddress
+        USING gin (upper("company") gin_trgm_ops);
+
+
+Also, if you use our ``pretix-shipping`` plugin::
+
+    CREATE INDEX CONCURRENTLY pretix_addidx_sa_name
+        ON pretix_shipping_shippingaddress
+        USING gin (upper("name") gin_trgm_ops);
+    CREATE INDEX CONCURRENTLY pretix_addidx_sa_company
+        ON pretix_shipping_shippingaddress
+        USING gin (upper("company") gin_trgm_ops);

 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}",

+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!

-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.
