This theme is a layout for WordPress. You can install http://wordpress.org for free and then use this free theme by installing it in the /themes/ directory in your wp-content folder. This theme should be installed in a subdirectory of /themes/ called /GrandFork/. By default GitHub unzips into a more verbose folder name which may also work but this setup may be problematic for child themes (if applicable).
[This information on the theme can also be found in the style.css file.]
