GH Pages do not allow the current code highlighter and thus must be updated to rouge
The page build completed successfully, but returned the following warning:
You are attempting to use the 'rogue' highlighter, which is currently unsupported on GitHub Pages. Your site will use 'rouge' for highlighting instead. To suppress this warning, change the 'highlighter' value to 'rouge' in your '_config.yml' and ensure the 'pygments' key is unset.
