What is Git?
A system that tracks every change to your code, letting you see history, undo mistakes, and collaborate with others
Why It Matters
Git prevents lost work, makes collaboration possible, and lets you experiment without breaking things
Real-World Example
If a new feature breaks your app, Git lets you instantly go back to the working version
“Understanding terms like Git matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
