First of all this looks pretty nice. I'm a docs nerd and as a whole I like this.
However ... It's slow. Docs should be static HTML. I should not ever wait for text content. If you want to async load some images or embeds that's fine, but I was waiting for the title to load!
As an aside I recently had a nice experience making a static docs site using Nuxt and Vue. Nice combination of dynamic development and fast performance in production.
