Git is a version control system that tracks changes in code, allows going back in time, collaborating, and avoiding mistakes.To start using Git, check if it's installed by running git --version, download it if needed, and get started.The typical Git workflow involves initializing a repository, making changes, staging the changes, and committing them.To create your first Git project, initialize a repository, add files using git add, set up a remote origin, and commit changes with git commit.
