+Special use cases
+-----------------
+
+### Using PostgreSQL instead of MySQL
+
+This image comes with full support for PostgreSQL as database driver. In this case, simply start a PostgreSQL database instead of MySQL:
+
+    $ docker run -d --name typo3-db \
+        -e POSTGRES_PASSWORD=yoursupersecretpassword \
+        -e POSTGRES_USER=typo3 \
+        -e POSTGRES_DATABASE=typo3 \
+        postgres:latest
+
+Then, proceed as before.
