Economy / Building Trees

Hello All,

I'm finally getting around to checking out the newest EB mod on the block. I loaded it last month and ran into problems. I think it was because I had installed the CAI and BAI in the wrong order, discovered my mistake and reinstalled everything from scratch. I've been playing around a bit since this past weekend and so far like what I see. I am trying to wrap my head around the economic and building aspects of the game. Are there any manuals, old previews or other documentation indicating building trees for the different factions?

I've done some searching but can't seem to find anything specific.

Thanks.
