Git has use version control
Design
Git's design was inspired by BitKeeper and Monotone. Git was originally designed as a low-level version-control system engine, on top of which others could write front ends, such as Cogito or StGIT. The core Git project has since become a complete version-control system that is usable directly. While strongly influenced by BitKeeper, Torvalds deliberately avoided conventional approaches, leading to a unique design.
