Hi Antistasi gurus!

I'm thinking of getting into this mod in a major way, but given the fork in its codebase (v1.8 and new branch) and lots of obsolete documentation on the old branch, I'm a bit confused!
- How do I obtain the very latest / best version and how do I install it?
- Could you point me to the best / most current documentation?
- What are the latest tutorial on how to play well?
- Is the mod still being developed?

Thanks!
