Oh my god I'm so fed up with GitHub. I literally can't figure it out
Try using GitHub Desktop, it helped me with getting my source code on GitHub. What you can do is take your project repository and make a copy of it, then navigate into this copy from the command line. Then (assuming you have Git installed) type 'git init' to initialize your copy for Git. From here you can go back to GitHub Desktop and upload you Git enabled copy to it, make a commit and upload it to GitHub.
