+## PostgreSQL
+
+Vikunja supports postgres, mysql and sqlite as a database backend. The examples on this page use mysql with a mariadb container.
+To use postgres as a database backend, change the `db` section of the examples to this:
+
+{{< highlight yaml >}}
+db:
+  image: postgres:13
+  environment:
+    POSTGRES_PASSWORD: secret
+    POSTGRES_USER: vikunja
+  volumes:
+    - ./db:/var/lib/postgresql/data

+{{< /highlight >}}

+You'll also need to change the `VIKUNJA_DATABASE_TYPE` to `postgres` on the api container declaration.

+<div class="notification is-warning">
+<b>NOTE:</b> The mariadb container can sometimes take a while to initialize, especially on the first run. 
+During this time, the api container will fail to start at all. It will automatically restart every few seconds.
