+## What is the use of `git`?
+
+* No need to fully rewrite code; **reuse code** and **save time**
+* Keep the changes you made over time (**history**)
+* Allows you to **backtrack** (if necessary) and undo unwanted changes
+* Easily **add contributions** of your collaborators to the main code base
+
+note:
+
+Other points to mention:
+* git shall not be considered as a nuisance, but as a tool that should help to track and trace the code.
+* git is not to track performance. Not using it shows exactly the opposite.
