+Gitea has been configured to work with MySQL; it can also be used with SQLite or
+Postgres. If you want to use it with a different database, change the 
+``DB_TYPE`` property in ``app.ini`` and change the line ``After=mysqld.service``
+in ``gitea.service`` to one of the following:
+
+* SQLite: comment it out.
+* Postgres: ``After=postgresql.service``

+Further information about configuring Gitea can be found at the
+`documentation <https://docs.gitea.io/en-us/>`.
