How does the Git version control system help manage projects and what is it used for?

Git is a distributed version control system that helps developers track changes in code, collaborate on projects, and manage different versions of a project. It allows you to save change history, revert to previous states, create branches for parallel development, and merge them.

Example of usage:

• You work on a new feature in a separate branch, without affecting the main version.
• After review and testing, changes are merged into the main branch.
• If something goes wrong, you can revert to a previous stable version.

Git is widely used for team collaboration and simplifies project management of any scale.
