Documentation missing

It is not clear what the certain parts of the source code mean.

• What's the purpose of the ForceFeedback.Setup project?
• What are the entry points (controllers) into the extension? What are the API classes/methods?
• Where does the CI, how does it work?

This all might seem obvious to the author of the code/infrastructure - but it's not for someone who is new to the repo. Getting up to speed quickly and easily however seems crucial if help is to be attracted.

I'm addressing this issue especially to you, @robinsedlaczek ;-) You're the only real contributor to the repo. It would greatly help if you could provide some info in the next couple of days so I can move forward efficiently with @matt-inteltech.
