-### Advanced configuration
+## Advanced configuration
Apart from the above described environment variables, the Docker image also allows to add custom config files
which are merged into Roundcube's default config. Therefore the image defines a volume `/var/roundcube/config`
Customized PHP settings can be implemented by mounting a configuration file to `/usr/local/etc/php/conf.d/zzz_roundcube-custom.ini`.
For example, it may be used to increase the PHP memory limit (`memory_limit=128M`).
+## Examples
+
+A few example setups using `docker-compose` can be found in our [Github repository](https://github.com/roundcube/roundcubemail-docker/tree/master/examples).
