Like Brian writes the main page is on the wiki here:

Well, it's an unsupported and abandoned programming tool developed by a third party so you're not going to find documentation at this level of refinement that you're describing.

If you need extensive documentation and tutorials I'd recommend using Grasshopper in Rhino instead, it's a similar system but it's actively developed and supported.

Any of those are fine.
