Git, a powerful version control tool, tracks changes to files in a project folder, saving each change as a commit. This allows developers to revert to previous versions, collaborate without overwriting each other's work, and avoid single points of failure. GitHub serves as the web interface for safely storing and sharing these versions, making it easier for teams to work together on projects.

The article outlines the importance of version control, which provides a clear, documented history of changes. This eliminates the chaos of managing multiple file versions and ensures that developers can experiment freely. By using Git, teams can track who made a change, when, and why, enhancing transparency and accountability in the development process.

Pushing code to GitHub involves several steps, including creating a repository, initializing Git, and using commands like `git add` and `git commit` to stage and save changes. GitHub then securely stores these changes, allowing collaborators to access and work on the latest version of the project. The process ensures that all team members have access to the most current files and can contribute seamlessly.

Pulling code from GitHub is equally straightforward, involving commands like `git pull` to update the local repository with changes made by others. This process ensures that everyone on the team is working with the most up-to-date information, reducing the risk of conflicts and improving overall efficiency.
