Is there a Manual?

I’ve been using AMP for a few months now and love it. There are a lot of things it can clearly do though that I don’t know how to implement (or even that they exist I am sure).

Is there a manual/PDF/instructions someplace that I am just missing that explains what all the individual settings are for or that gives examples? I know a lot of it is self-explanatory and can be figured out by just playing around, but I generally would like to avoid doing something that may break what I have set up.

I would like to get more info on User and Role management and implementation uses for example and info on the external services tab, template uses/examples, even something basic about installing instance game servers in differing locations. Is this out there somewhere and I am just missing it?
