I quite agree here. I've used git about six months now and I'm quite 
familiar with the porcelain layer. I don't even care about the plumbing 
(even though I've used some plumbing commands in a script).

Anyway, to me the index wasn't difficult. It took about two days to be 
_comfortable_ enough with the idea of staging area for commits but it 
wasn't too hard. I have been a lot more confused with the

    git reset <commit> -- <file>
    git checkout <commit> -- <file>

business. These commands still aren't completely clear to me but it has 
been helpful that "git status" prints info about how to get back changes 
from the index. I think the info is a good idea because "git status" is,  
to me at least, a general "give me some clue" command.

I think the confusion with reset and checkout comes from the fact that 
first I learned that "git checkout" changes branches and later that it 
can actually check-out any commits. Checking out a file to overwrite one 
in the working directory is something I'd expect from "git reset". 
I don't think that documentation would have helped much; it's more about 
the double meaning of the commands.
