Very interesting! The first static CMS I've seen that isn't just an API. I've used http://prose.io in the past to edit content in GitHub, but this seems nicer. Currently I'm using WordPress as a CMS and Gatsby as a frontend, mostly due to custom post type support. I need more than posts/pages.
Does this support custom post types? I believe Hugo does.
