Add existing repo to gitlab:
git init
touch README
git add README
git commit -m "first commit"
git remote add origin git@gitlab.com:yourname/your_file.git
git push -u origin master
If error "fatal: remote origin already exists" occurs:
Seems like remote origin is already there somehow and you want to change its uri to another value. You can't add origin since its already there but you can update it. Instead of git remote add
command, you can run:
git remote set-url origin git@gitlab.com:yourname/your_file.git
