What is Git Git is a distributed revision control system with an emphasis on speed. Git was initially designed and developed by Linus Torvalds for Linux kernel development. Every Git working directory is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server. The central repository holds two main branches and a number of feature branches: master: The main branch where the source code of HEAD always reflects a state with the latest delivered development changes for the next release.
