Git is a free, open-source distributed version control system designed to handle everything from small to very large software projects with speed and efficiency. Unlike centralized version control systems, it lets every developer have a complete local copy of the project’s repository, enabling them to work independently on changes, track modifications to files over time, and create separate branches to experiment with new features without disrupting the main codebase. It simplifies collaboration by allowing developers to merge their work back into shared branches, resolve conflicts when changes overlap, and easily revert to previous versions of the code if needed—all while maintaining a detailed, transparent history of every commit made to the project.
