At Ionic, we use Dgeni (<a href="https:&#x2F;&#x2F;github.com&#x2F;angular&#x2F;dgeni" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;angular&#x2F;dgeni</a>) for API docs. We have a few custom build tasks that allow us to version the API docs.<p>We also have higher level documentation, which is meant to serve as a sort of conceptual overview of the framework, as well as to show what the framework comes with out of the box. This section is written mostly in kramdown, which gets parsed by jekyll before it&#x27;s turned into HTML.
