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.
