Git has become the most widely used system for version control and sharing code. If you want to help build open-source software, or if you want to work on a professional team, understanding Git is a must.

In this Coffee Break series, Envato Tuts+ instructor Ed Wasserman will explain some of the fundamentals of Git. Follow along as Ed explains core Git concepts, all illustrated with helpful animations.

In this course, you'll learn about the three trees: the HEAD, the index, and the working directory. Watch as Ed explains the role of each and how they interact as you update and commit code.
