DESCRIPTION
Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level
operations and
full access to internals.
See gittutorial(7) to get started, then see Everyday Git[1] for a
useful minimum set of commands. The Git User’s Manual[2] has a more
in-depth introduction.
After you mastered the basic concepts, you can come back to this
page
to learn what commands Git offers. You can learn more about
individual
Git commands with "git help command". gitcli(7) manual page
gives you
an overview of the command-line command syntax.
Formatted and hyperlinked version of the latest Git
documentation can
be viewed at http://git-htmldocs.googlecode.com/git/git.html.
