This is an AMP compatible WordPress theme built on top of WP Rig, more specifically a custom fork of WP Rig.
The design of the theme was generally taken from the "Beck & Galo" demo template on the amp.dev website.
git clone git@github.com:felixarntz/beck-and-galo.git wp-content/themes/beck-and-galo-devcd wp-content/themes/beck-and-galo-devcomposer install && npm install && npm run build
You can actually run this version and you should run it for development, but this version shouldn't be deployed on a production site.
npm run bundle
The production theme will be located in a new wp-content/themes/beck-and-galo directory, alongside a ZIP file of it.
