tinyGit is a version-control system that mimics some of the basic features of the popular system Git. It implements many basic commands of git, such as add, remove, branch, merge, etc. By learning the source code of tinyGit, you can understand the essence of git and it will be no longer mysterious to you.
tinyGit comes from cs61b, an awesome course about data structures. Thanks to Professor Hug for opening up the course-related materials, I learned a lot from this course.
Warning: If you are taking this course and doing this project, I strongly recommend that you close this page and implement it yourself.
