This chapter will explain how to use Git and GitHub to track version history and collaborate with others. It will also introduce command line basics in the process.

Git is, by far, the most powerful tool in a programmer's arsenal. It is a command line tool that allows you to do a lot of things with your code, including but not limited to:

  • Track changes to code

  • Allow you to work on certain parts of the code without impacting known good code or messing with other people's work

  • Revert changes to code in case something breaks

  • Automatically merge different sets of changes so that you (mostly) don't have to do it yourself

This chapter will get you started on the basics of Git.
