When you want to push your local branch to remote branch, for the first push:
git push --set-upstream origin <branch_name>
The reason to set ‘up-stream‘ is that you want this branch to be tracked against, so you can just type:
git push
Tips:
git push -u origin <branch_name>
is the same the --set-upstream
