I want to use FCC offline, is there a guide for it?

sorry if this has been asked, but the only posts i saw were like 4 or 5 months old, and i didn’t understand anything, is there like a guide for it?, or is it just using the github repo?
and if it is the latter; please tell me what can i do, cuz i’m really new to this.
thanks in advance!

thanks, i will work through it now, because i can’t sleep xD
