@dgr Right. I can suggest a few vids by @daviwil:
youtu.be/iBaqOK75cho
youtu.be/oSy-TmoxG_Y

and my very old stream recording on Guix System Installation:
youtu.be/XOYirIzUlW8?list=PLZm

I hope someday I'll find a time to prepare a well-made video series.

Anyway, if you don't figure out yourself soon, just ping me here or on IRC/ML.
