Create Repo from GitHub site. Step 1. Create a local source control path Step 2. Got to Git Bash Step 3. initialize the git       Linked or remote origin $ git remote add origin " https://github.com/shubh1984/SampleProject.git "       Pull $ git pull origin master     Status $ git status     Adding file to local repo $ git Add file name $ git add -A      [add all]     Commit $ git commit filename -m "commit comment" $ git commit -a -m "commit comment"    [commit all]     Push to remote server $ git push  origin master $ git push -f origin master     Fetch [need to do merge]
