Setup GitHub Pages "gh-pages" branch as a subfolder within the "master" project on your local checkout - a step-by-step guide.

Intro

Setup GitHub Pages "gh-pages" branch as a subfolder within the "master" project on your local checkout.

IMPORTANT

If you plan on switching between different branches (e.g. git checkout master-experiment then revert back with git checkout master) you will loose your child folder from this tutorial (because it's in your .gitignore and is not part of your master branch).
