What is Git? GIT is a very popular and efficient open source Version Control System. It tracks content such as files and directories.
Git is, first and foremost, a version control system (VCS). There are many version control systems out there: CVS, SVN, Mercurial, Fossil, and, of course, Git.
Git serves as the foundation for many services, like GitHub and GitLab, but you can use Git without using any other service. This means that you can use Git privately or publicly.
A staggering number of software projects rely on Git for version control, including commercial projects as well as open source. Developers who have worked with Git are well represented in the pool of available software development talent and it works well on a wide range of operating systems and IDEs (Integrated Development Environments).
