There aren't any.
There was one, but it was removed due to too many stupid questions.
The best thing to do is search around the forum where there are various resources~
Jason Baum's site of ZBLS, Simon Swanson's pdf of ZBLL, I think Lars has some ZBLS too, and there's always the wiki.
ZB is something you gotta find yourself because with 493 algorithms there isn't someone who's gonna teach, and the recognition is all that has to be learned and thats:
Normal orientation (or whatever it's called), COLL case, which of the 12 ZBLL cases it is.
So because COLL becomes second nature you just have to look at how
FU & FRU relate, or how FU and RFU relate
and how
RU & RFU relate, or how RU and FRU relate.
edit: if you want -something- this is all i can give:

it's basically to make it seem easier.
