Stuck in contributing

Hey,
I would like to contribute to the project. I have read everything I found about this subject but I am stuck when I tried to git push my commit.

As you can see I have a local labelResize branch but I guess I should somehow create its remote pair. Which I failed to do so. Maybe I should create a PR from a fork?
Thank you,
Szurilo
