Learn what Git is and how it can help you:
Git is an Open Source Distributed Version Control System
Version Control: Git is effectively a content tracker, used mainly to work with code. This code keeps changing as different developers work with it in parallel. A Version Control System helps in maintaining a history of the changes that are made.
Distributed: Git works with local repositories on each local computer, together with a remote repository on a server. Since a full copy of the code is synchronized on each local computer, this system is distributed.
