 ### More about Git
 Git is a version control system. A version control system (VCS) manages and tracks changes to files over time, allowing multiple users to collaborate efficiently on projects. It records a history of changes, supports branching for parallel work, and helps merge or resolve conflicts. It ensures a consistent project state and enables reverting to previous versions when needed.

 We could summarize the key principles of Git as follows: 
 
-- Tracking changes: Git records a history of changes (commits) to a project, making it easy to review, undo, or revert to previous versions.

-- Branching and merging: Developers can create branches to work on new features or fixes independently, then merge these changes back into the main project.
