Course Description

Version control is one of the power tools of programming. It allows you to keep track of what you did when, undo any changes you have decided you don't want, and collaborate at scale with other people. This course will introduce you to Git, a modern version control tool that is very popular with data scientists and software developers alike, and show you how it can help you get more done in less time and with less pain.

  1. 1

    Basic workflow

    This chapter explains what version control is and why you should use it, and introduces the most common steps in a common Git workflow.

  2. 2


    This chapter digs a little deeper into how Git stores information and how you can explore a repository's history.

  3. 3


    Since Git saves all the changes you've made to your files, you can use it to undo those changes. This chapter shows you several ways to do that.

  4. 4

    Working with branches

    Branching is one of Git's most powerful features, since it allows you to work on several things at once without tripping over yourself. This chapter shows you how to create and manage branches.

  5. 5


    This chapter shows Git's other greatest feature: how you can share changes between repositories to collaborate at scale.
