I think you should delete this repository and do it again, but this time with the right branch.
You mentioned that you have 3 folders, but you want to use only one folder. So go to your folder with git.
This is an example in Git - Bash
cd /path/to/your/folder git init git add --all git commit -m "My first commit." git push origin master
The origin should be the address of github-repository.
