+If you use `jekyll-github-metadata` (you do if you use the `github-pages` gem),
+a link to the GitHub repository is added at the end of the navbar.
+Customize the link text and the icon by setting
+`site.settings.navbar.github.link` and `site.settings.navbar.github.icon`
+accordingly.
+Hide the link by settings `site.settings.navbar.github` to `false`.
