Too Long; Didn't Read
A good practice is to name the branch with the focus of your edit. Make it a habit to do small changes so it's easy to go back if you mess up. Git will compain because GitHub doesn't know about your new branch. If you want to delete a branch, go to the main branch then delete our branch from there. This is what I learned in an hour, with an example of the main repository from a mentor from a Git mentor. The tips to use Git are: create a new branch, checkout, add, commit and push to remote repository.
