Git

The most popular version control system in the world today is Git.
Git is an actively maintained open source project originally developed in 2005 by Linus Torvalds, the creator of Linux.

1000’s of software projects rely on Git for version control, including commercial projects as well as open source.

Having a distributed architecture, Git is an example of a DVCS (Distributed Version Control System).
With Git, every developer’s working copy of the code is also a repository that can contain the full history of all changes.
