Install Git on your computer and configure your name and email.
Git is open source software (free for anyone to use) written by Linus Torvalds who also wrote the Linux operating system.
It is a program for keeping track of changes over time, known in programming as version control.
Git isn't like other programs on your computer. You'll likely not see an icon on your desktop, but it will always be available to you and you'll be able to access it at anytime from your terminal (which you're using in Git-it!) or Git desktop applications (like GitHub for Mac or Windows).
Once it is installed, open terminal (aka Bash, aka Shell, aka Prompt). You can verify that it's really there by typing:
$ git --version
This will return the version of Git that you're running and look something like this:
git version 1.9.1
(Any version 1.7.10 or higher is fine.)
Next, configure Git so it knows who to associate your changes to:
Set your name:
$ git config --global user.name "<Your Name>"
Now set your email:
$ git config --global user.email "<youremail@example.com>"
git-it verify git-it
Dollar signs $ are often used in programming documentation
to signify that the line is command line code (see the code snippets above). You don't actually
type the $ in though, only type what comes after. For instance, to run the verify command above, you're actually going to type git-it verify into terminal.
