to check user email : 
git config user.email

STEP 3 (Initialize the folder of the project i.e it creates ".git" hidden folder)
git init

STEP 4 (set origin to remote repository)
git remote add origin http-link-address-from-git-repository

STEP 5 (to pull initial files if you created the project directly in GitHub for the 1st time)
git pull origin master
Similarly to pull the development branch changes to checked-out feature branch using
git pull origin development
And if restricted the use --allow-unrelated-histories

STEP 5 ( check the remote url, if not: git remote rm origin & git remote add origin url-of-repo )
git remote -v

STEP 6 ( now push stagged files)
git push -u origin master


//////////////////////////////////////////////////////////
STEPS TO UPDATE LOCAL REPO FROM CHANGED GITHUB REMOTE REPO
