 configurable on your Admin page, so it is usually not necessary to edit
 ``config/config.php``.
 
+ownCloud provides a feature of loading config parameter from multiple files.
+You can add arbitrary files ending with `.config.php` in the `config/` directory
+and all parameter from these files will be loaded. In this way you can specify
+common attributes like the email setup in a file called `email.config.php` that
+contains only the email related parameters. This enables an easy deployment of
+config parameters. Another advantage is, that those parameters can't be
+overwritten by ownCloud. Aslo the values in those files overwrite the values of
+`config.php`.
