Our documentation should never promote storing credentials inside the repository. The merging hell resulting from this can cause too many problems. It's better to rely on the platform to provide the credentials inside the runtime environment. For services not provided as an add-on like e.g. S3, customers can use the [custom config add-on](https://www.cloudcontrol.com/add-ons/config) to setup the credentials per deployment.

I suggest we extend this section to include a how to set the S3 credentials using the custom config add-on via cctrlapp and also how to read them inside this property file that I understand to be Java specific.
