Git is a version control system used to track changes in computer files and coordinate work on those files among multiple people. It is commonly used in Drupal development to manage the source code of a website or web application. Git allows developers to work on the same codebase simultaneously, while also providing a way to track changes and revert back to previous versions if needed.

Git is a distributed version control system, meaning that it stores copies of the codebase on each developer’s computer. This allows developers to work on the codebase without needing to be connected to a central server. When a developer is ready to share their changes, they can push their changes to a remote repository, such as GitHub or Bitbucket. This allows other developers to pull the changes from the remote repository and incorporate them into their own local copy of the codebase.

Git also provides a way to track changes over time. Each time a developer commits their changes, a new version of the codebase is created. This allows developers to easily view the history of the codebase and revert back to previous versions if needed. It also allows developers to easily collaborate on the same codebase without having to worry about overwriting each other’s changes.

Git is an essential tool for any Drupal developer. It allows developers to easily collaborate on the same codebase, while also providing a way to track changes and revert back to previous versions if needed. It is also a great way to keep track of the history of a codebase and ensure that changes are properly documented.
