You can safely skip this section if you're comfortable with Git.

Git lets you track a history of changes to files, and helps ease the pain of multiple people working on the same set of files. Git is a distributed version control system, meaning every developer owns a mirrored copy of the code base on their system.

If you're on a Debian-flavored Linux distribution, you can install Git by running the following:

$ sudo apt-get install git

If you're on a different system, you can download the binaries or find more instructions from git-scm.com/download. You'll want to configure your username and your email address:

$ git config --global user.name 'Your Name'
$ git config --global user.email 'your@email'

You're now ready to use Git! If you find yourself stuck, Git has an extensive help system (in addition to a set of tutorials on git-scm.com):

$ git help
