Admin UI User Guide

I’m a new user, so I apologize in advance if this question has been asked and answered (I did search the forums first).

I have been able to get the base install of Cockpit up and running, modeled and populated a few collections and singletons and also was able to do a basic API call to pull this information back into my application. What I am missing is detailed documentation or user guides for the various options available on the Admin UI. I’ve reviewed all the documentation on the main site and that helped me with overall understanding. I am looking for something specific to the Admin UI (editorial experience) itself.

Thanks in advance for any pointers!
