What is Git and Why Version Control is Important
Git is a version control system that helps you manage different versions of your code in an organized way.

Why Version Control Matters:
Track changes: See exactly what changed, when, and why.
Collaborate: Multiple people can work on the same project without overwriting each other's work
Undo mistakes: Revert to previous versions if something breaks
Experiment safely: Try new features without breaking your main project
