Updates were rejected because the remote contains work that you do hint: not have locally. T code example
Example 1: Updates were rejected because the remote contains work that you do
git pull origin master
git push -u origin master
Example 2: updates were rejected because the remote contains work that you do
git remote add origin [//your github url]
//pull those changes
git pull origin master
// or optionally, 'git pull origin master --allow-unrelated-histories' if you have initialized repo in github and also committed locally
//now, push your work to your new repo
git push origin master
