Git

Git is a distributed version control system: a tool that records every change made to a project’s code and keeps a full history you can always return to. It lets many developers work in parallel through branches, where each experiments separately and then merges their changes without overwriting anyone else’s work. If something breaks, you can roll back to an earlier version. Because it is distributed, every person has a complete copy of the history on their machine. It was created by Linus Torvalds, the same author as Linux.
