The pages included below this one have been created to provide more simplified examples of how new pages can be out together.
A copy of these page have also been included as the pages-template.json file found in the build folder in your Github Repository
If you just want to start working from this simpler example just re-name your existing pages.json file to something like pages-old.json and re-name the pages-template.json file as pages.json. This will force GitHub to rebuild your website based on the simpler example.
