Git Quick Overview

What is Git ?

Git is a leading, free, open source, distributed, most powerful and most commonly used version control system (VCS), which is designed by Linus Torvalds for tracking changes in source code during software development. It is mainly design for coordinating work among programmers to handle everything from small to very large projects with speed and efficiency.
