I have a cloned project from a master branch from remote repository remote_repo. I create a new branch and I commit to that branch. Other programmers pushed to

git pull [master branch]

2.Now rebase source-branch with master branch

git checkout [source branch]
git rebase [master branch]
git pull [source branch] (remote/source branch)
git push [source branch]

IF source branch does not yet exist on remote then do:

git push -u origin [source branch]

"et voila..."
