I have a project which I want to upload to GitHub. I have used Github Desktop to create a local repository and I am able to commit files to it. But once I try to publish it, the publish icon just fades and won't allow me to do it. I have checked my settings in Settings->Options
and they are correct.
Since the local repo has no remote url, you need to add one, referencing a remote empty repo that you own (on GitHub for instance):
cd /path/to/repo
git remote add origin https://github.com/<user>/<an_empty_repo>
Or, in GitHub Desktop:
Settings->Repository settings->Remote
Then you will be able to publish.
