For more information about publishing sources, see "About GitHub Pages."
Before you configure a publishing source, make sure the branch you want to use as your publishing source already exists in your repository.
On GitHub AE, navigate to your site's repository.
Under your repository name, click Settings.
In the left sidebar, click Pages.
Under "GitHub Pages", use the None or Branch drop-down menu and select a publishing source.
Optionally, use the drop-down menu to select a folder for your publishing source.
Note: If your site has not published automatically, make sure someone with admin permissions and a verified email address has pushed to the publishing source.
If you choose the
docs folder on any branch as your publishing source, then later remove the
/docs folder from that branch in your repository, your site won't build and you'll get a page build error message for a missing
/docs folder. For more information, see "Troubleshooting Jekyll build errors for GitHub Pages sites."
