Ciao a tutti, nel mio canale YouTube: https://www.youtube.com/channel/UCQ7W_INpFFlYF68vDIx6UBA
potete trovare dei tutorial base per imparare il programma Grasshopper.
I believe there is Italian Discourse forums of McNeel.
I’d love to see your tutorials translated in English, then it would make sense to give a link here. 
If you want there is also automatic translation on YouTube.
Unfortunely i m not very well in English:(
