https://www.atlassian.com/git/tutorials/setting-up-a-repository/git-init


Start from the beginning, because we need to initialize the git empty repository for our project.


	$ git init   - if encountered any error for git , just install, 

	$ sudo apt-get install git

If want to remove already created git. 

	$ rm -rf .git
