+## Basics of GIT for web-dev beginners👶
+
+
+## What is `Git`?
+      1. Git is a distributed version control system.
+      2. The entire codebase and history is available on every developer’s computer, 
+         which allows for easy branching and merging.
+      3. It is used as Version Control System (VCS) for tracking changes in computer files.
+      
+* Distributed version control
+* Coordinates work between multiple developers  
+* Who made what changes and when
+* Revert back at any time
+* Local & remote repos
+
+## CONCEPTS OF GIT
+* Keeps track of code history
+* Takes "snapshots" of your files
+* You decide when to take a snapshot by making a "commit"
+* You can visit any snapshot at any time
+* You can stage files before committing
+
