================================================================================
When you have a directory
in which you want to do version mangement,
you need to let git to know that directory,
and you need to initialize that directory.
Enter that directory, and run
git init
================================================================================
After you run
git init
you'll get a folder named .git
When you do version mangement,
the various data like a history of changing codes, etc is generated,
and the various data is stored in this .git folder
