Reading First things first: Git manual

Man (manual) pages hold the documentation on *nix systems.

You can access the man page for a git command with either of:

git <command> --help

git help <command>

man git-<command>

Example:

git commit --help

git help commit

man git-commit

Man pages open in a pager, usually less .

So you navigate them with the usual less bindings (e.g. Space to scroll down and q to quit).

To get a list of the options for a command, run:

git <command> -h

Example:

git commit -h
