Git is a DevOps tool for managing source code. It is one of the most well-known version control systems (VCS) in use today and is frequently used to efficiently manage both small and large projects. It aids in tracking source code changes, allowing many individuals to work together on various aspects of the same software.

Linus Torvalds developed the free and open-source version control program named as Git in 2005. Git is distributed, in contrast to prior centralized version control systems like SVN and CVS; each developer has a local copy of the complete history of their code repository. As a result, following activities like commit, blame, diff, merge, and log are much faster than the first clone of the repository.  Git also provides great branching, merging, and rewriting functionality, which has produced a lot of creative and effective workflows and tools. One such well-liked tool that enables teams to work together on Git branches and quickly assess each other's code is pull requests. The most popular version control system in use today is called Git, and it is regarded as the modern standard for software development.
