Git

Git is a distributed version control system to track changes in source code. Git was created by Linus Torvalds in 2005 for Linux kernel development. Git is the most widely used version control system. You could use git on a command line or using a graphical UI. You can use Git to travel back in time with respect to your source code and make changes.
