Git (along with its cloud interface GitHub) is undoubtedly the most common version control tool in the field of programming and software engineering today. Even if you are not using Git and GitHub to facilitate version control for your projects, you actually have already interacted with GitHub in a sense when downloading the code repository for this book!

In this section, we will go into details about how to get started as a Git user (if you are not already one), and various options available for the facilitation of version control. Again, if you are already an experienced Git user, feel free to skip to the next section to learn about the integration of Git in PyCharm.
