Deploying a subfolder to GitHub Pages
Sometimes you want to have a subdirectory on the
master branch be the root directory of a repository’s
gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the
master branch alongside the rest of your code.
For the sake of this example, let’s pretend the subfolder containing your site is named
dist directory from the project’s
.gitignore file (it’s ignored by default by Yeoman).
