Grasshopper Reference ?

Hi all,

I'm totally new to Rhino & Grasshopper but i know C# and VB (slight preference for C# however).

The problem is, impossible to find any reference ; even after 30' of hard-search. Feels like knowing Chinese but no vocabulary, hence, it's quite hardcore to communicate with Grasshopper.

Thanks in advance, hoping such a thing exist =3

PS : A reference is like that http://www.cplusplus.com/reference/
