Git is the most popular version control system in the Drupal community. All of the core and contributed code development happens in Git repositories. It is also a popularly supported choice among the major hosting providers. Learning how to use Git will make it easier to collaborate with the Drupal community, and help you manage your own development process.
- Interact with Drupal core and contributed code in order to participate in the development process.
- Use version control on personal projects to ensure work isn't unintentionally lost
While improvements are made to the Git software on a regular basis, the basic commands you need to know in order to interact with the Drupal community (and your codebase) are quite stable.
