Had issue with these before first set up ssh bcz seemingly github is no longer accepting https authentification. step 1. watch this video: https://www.youtube.com/watch?v=du3AnclSQys&list=PLCRqvOk_BGhUcqxZbO2fZvC0nw8vWcgbE&index=5 to generate ssh key on the system and match it up with github ssh auth. step 2. having done this, you can then follow github guide that you see after creating a new repo.
