<s>[INST] This is my first time using the editor of my Mac, and I used source control with git to upload some files in my local computer to gitlab. However, when i check to make sure that the files were uploaded to the repository, i realized that i made a mistake. Instead of pushing it to a 'universal' branch, I made a new Branch called 'universal'. What do I need to do to merge and get rid of the unnecessary branch?[/INST]
