Configuring a custom domain for your GitHub Pages site
You can customize the domain name of your GitHub Pages site.
Who can use this feature?
GitHub Pages is available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server. For more information, see GitHub’s plans.
GitHub Pages now uses GitHub Actions to execute the Jekyll build. When using a branch as the source of your build, GitHub Actions must be enabled in your repository if you want to use the built-in Jekyll workflow. Alternatively, if GitHub Actions is unavailable or disabled, adding a .nojekyll file to the root of your source branch will bypass the Jekyll build process and deploy the content directly. For more information on enabling GitHub Actions, see Managing GitHub Actions settings for a repository.
