Git

Git is "version control" software that is typically used in command-line. It is how developers keep track of versions of their software, collaborate with other developers, and merge code between developers. Git uses the concept of a "repository" to track various details about your code in your project. You can host your repository with GitHub or similar Git hosting services to help with collaboration between developers. It's worth noting to beginners that GitHub does not own and did not create the Git technology.
