+
+This hack will add classes on the HTML root element, and hide some components when displayed inside an iframe.
+
+This can be useful use Bookstack as a Knowledge Base, and you want to integrate contextual help for your app, with content from Bookstack.
+
+#### Considerations
+
+This works via JavaScript, so is not assured to run since a user could have
+JavaScript disabled although this is relatively rare.
+
+### Usage
+
+Use the original page url, with the GET query params `iframe=true` and `theme=dark|default`.
+
+For example: `bookstack-instance.io/books/my-book/page/my-page?iframe=true&theme=dark`
+
+#### Code
+
+{{<hack file="head.html" type="head">}}
