CG organization (Git)

[Urs Liska]

I'm somewhat confused about the organization of the CG chapters about 
Git and patch review.

First:
3.2.2 Git for the impatient and
3.3 Basic Git procedures

share some information, and this in a somewhat confusing way.
Is there a _short_ explanation what these two chapters are intended for?

Second:
3.2. seems to be targeted at absolute beginners.
So why does it explain the workflow with pushing to staging?
Anybody who needs to read this chapter won't have commit access.


I wanted to add my experiences from the review cycle to the CG, but now 
I'm confused and don't know _where_ to put them.
