This was classic Torvalds — zero hand holding. But he gets away with it because the way git works is brilliantly appropriate for what it’s intended to do (if you just ignore the part where, you know, mere mortal humans need to use it sometimes). I ended up writing my masters thesis a decade ago about the version control wars, and I (somewhat grudgingly) came away in awe at Torvalds’ technical and conceptual clarity on this.
