what's up with the git instructions?

[Graham Percival]

We used to have a nice set of cut&paste instructions.  But now, in
order to get git running, I need to copy&paste from two different
sections, ignore a bunch of chit-chat, and manually type in
  git checkout -b master origin/master

I think this is a step backwards.  Granted, we have lily-git now, so
it's not as pressing an issue, but I still think it's a step
backwards.

Cheers,
