People with admin permissions for a repository can configure a publishing source for a GitHub Pages site.
For more information about publishing sources, see "About GitHub Pages."
Choosing a publishing source
Before you configure a publishing source, make sure the branch or folder you want to use as your publishing source already exists in your repository. For example, before you can publish your project site from the /docs folder on the master branch of your repository, you or a collaborator must create a /docs folder on the master branch of your repository.
- On GitHub, navigate to your site's repository.
- Under your repository name, click
Settings.

- Under "GitHub Pages", use the Source drop-down menu and select a publishing source.

Troubleshooting publishing problems with your GitHub Pages site
Note: If your site's source files are located in the default publishing source—master for user and organization sites or gh-pages for project sites—but your site has not published automatically, make sure someone with admin permissions and a verified email address has pushed to the default publishing source.
If you remove the /docs folder from the master branch after choosing the docs folder as your publishing source, 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."
