I think that EB is a splendid achievement, but I am having problems with it.

1: I cannot find a manual, either in the documents folder or on Google.

Specific Qs: what are all these types of homelands and governments?

I am told that homeland allows recruitment of freed slaves (rebellion
only 1) What does this mean? I dont see anything relevant in the
recruitment panel.

but my real Q is: where is the manual?
