Find a way to automatically create Ops documentation

Current situation:

There's no way to explain Ops what valid parameters/values for the environment configuration (yaml) are available, other then manual documentation.
Devs need to create some outside documentation, e.g. an annotated example environment description or documentation text descriping the variables used by the templates.

Improvement:

It would be helpful, if there was an automated way to create configuration documentation based on the template scripting during configuration generation.
