One remark about the Git Usage section:

TL,DR: no need to require "git mv" to move files, thing will work 
exactly the same without.

Requiring developpers to use git mv doesn't make sense at all since git 
doesn't store any information as to where some piece of code comes from, 
contrary to all other VCSes that I know of. (git mv is just a shortcut)

Instead, git always stores the full tree for each commit (and the 
storage is efficient because it is content-adressed and deltafied after 
the fact).

BUT, git uses heuristics to recover file movements when requested. It 
has two upsides:

- If you don't git mv but move files in your explorer and git add -A, it 
doesn't matter
- git can detect partial files moves, or file merges, and preserve 
history for a single *function* that moved several times across several 
files. No other VCS does it AFAIK.
