In this chapter, we looked at the version-control system known as Git and its close sibling, GitHub. Git was developed by Linus Torvolds in 2005 to help develop the Linux kernel and later adopted by other open source projects as the source-control system. Git is a fast, distributed, and scalable system. GitHub provides a centralized location to host Git repositories on the internet that allow anybody with an internet connection to collaborate.

We looked at how to use Git in the command line, its various operations, and how they are applied in GitHub. We also studied two of the popular Python libraries for working with Git: GitPython and PyGitHub. We ended the chapter with a configuration backup example and notes about project collaboration.
