+```
+### Initializing and migrating database
+On the first start, the database must be initialized (the Tables created and so on).
+When updating the project the database must be migrated.
+Both are done using the `migrate` command.
+
+This can be done manually by running the following command after the container has started:
+`docker-compose exec -it akplanning-server ./manage.py migrate`
+
+It can also be done automatically on each container start by setting `AUTO_MIGRATE_DB` to the string `true`
+(as shown in the docker-compose file above).
+
+Database migration may lead to the corruption or loss of data in some cases.
+Make sure you have a backup before running the command and be very careful with enabling auto migration.
+
+### Creating initial superuser
+There are two ways to create the initial superuser when using the docker container.
+For both the database must have been intialized before.
+
+The first way is already shown in the docker-compose file above:
+Using the environment variables `DJANGO_SUPERUSER_{USERNAME,EMAIL,PASSWORD}`.
+
+The second way is to run the following command after the container has started:
+`docker-compose exec -it akplanning-server ./manage.py createsuperuser`
+
+### Extra django settings
+For simple cases you can pass environment variables starting with `EXTRA_DJANGO_SETTING`.
+The content of such variables is written into python files, which are loaded as settings.
+
+For more complex scenarios you can also mount a docker volume to `/app/AKPlanning/settings` and add any number of python files to the volume.
+
 ## Updates
 
-To update the setup to the current version on the main branch of the repository use the update script ``Utils/update.sh`` or ``Utils/update.sh --prod`` in production.
+To update the setup to the current version on the main branch of the repository use the update
+script ``Utils/update.sh`` or ``Utils/update.sh --prod`` in production.
 
 Afterwards, you may check your setup by executing ``Utils/check.sh`` or ``Utils/check.sh --prod`` in production.
 
+### Updating when using docker
+
+To update when using docker, just switch the tag of the image for `akplanning-server`.
+Then (if `AUTO_MIGRATE_DB` is not enabled), do a database migration as described in [Initializing and migrating database](#initializing-and-migrating-database)

 ## Structure
 
 This repository contains a Django project called AKPlanning. The functionality is encapsulated into Django apps:
 
-1. **AKModel**: This app contains the general Django models used to represent events, users, rooms, scheduling constraints etc. This app is a basic requirements for the other apps. Data Import/Export also goes here.
-1. **AKDashboard**: This app provides a landing page for the project. Per Event it provides links to all relevant functionalities and views.
-1. **AKSubmission**: This app provides forms to submit all kinds of AKs, edit or delete them, as well as a list of all submitted AKs for an event.
-1. **AKScheduling**: This app allows organizers to schedule AKs, i.e. assigning rooms, slots, etc. It marks conflicts of all modeled constraints and assists in creating a suitable schedule.
-1. **AKPlan**: This app displays AKs and where/when they will take place for each event. Views are optimised according to usage/purpose.

+6. **AKOnline**: This app contains functionality for online/hybrid events, such as online rooms (links for video or
+   audio calls).
+7. **AKPreference**: This apps facilitates the submission of preferences for AKs, so each participants can mark which
+   AKs they would like to visit, to facilitate better scheduling.
+8. **AKSolverInterface**: This app provides an interface to an automatic solver, a tool that can be used to generate
+   schedules based on the submitted AKs and preferences.
 
 ## Setup instructions
 
 See [INSTALL.md](INSTALL.md) for detailed instructions on development and production setups.
 
-To update the setup to the current version on the main branch of the repository use the update script ``Utils/update.sh`` or ``Utils/update.sh --prod`` in production.
-
-Afterwards, you may check your setup by executing ``Utils/check.sh`` or ``Utils/check.sh --prod`` in production.

 ## Developer Notes
+
 * to regenerate translations use ````python manage.py makemessages -l de_DE --ignore venv````
 * to create a data backup use ````python manage.py dumpdata --indent=2 > db.json --traceback````
+* to export all database items belonging to a certain event use
+  ````./Utils/json_export.sh <event_id> <export_prefix>  [--prod]````. The results will be saved in
+  ````backups/<export_prefix>.json````
