+Setup database and message broker
+---------------------------------
+
+AlekSIS requires `PostgreSQL`_ (version 13 or newer) as database

+`aleksis` on Debian::
+
+  sudo apt install postgresql-13
+  sudo -u postgres createuser -P aleksis
+  sudo -u postgres createdb -O aleksis aleksis
+
+Additionally, `Redis`_ is used as message broker and for caching.
+The default configuration of the server in Debian is sufficient::
+
+  sudo apt install redis-server

 Get the source tree
 -------------------
 
 To download AlekSIS and all officially bundled apps in their
 development version, use Git like so::
 
-  git clone --recurse-submodules https://edugit.org/AlekSIS/AlekSIS
+  git clone https://edugit.org/AlekSIS/official/AlekSIS
 
-If you do not want to download the bundled apps, leave out the
