git push -u origin <branch>?

Git is a Source Control versioning tool for software development.

When you develop new features or a bug fix, it is good practice to run in a new branch.

When you are ready to update the server with your new branch, you would run git push

Git will tell you that you are in a new branch and so you need to set up tracking (link your local to remote branch) to enable push and pull to know where it should be linked to.

git config --global push.default current
