What is Git?

Git is a free and open-source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. It was created by Linus Torvalds in 2005 to manage the development of the Linux kernel. Git allows multiple people to work on the same codebase simultaneously and track changes made to the code over time. It also makes it easy to revert changes, collaborate with others, and manage code releases.
