# External content

Anything goes - right inside your cBook!

With this feature, virtually any content can be seamlessly integrated into the cBook.

### Technical requirements

There is only one requirement:

**Upload a ZIP file containing at least one index.html file.** Everything else is up to you!

### What can you include?

-   Exports from other authoring tools like Storyline
-   Self-created mini-websites using HTML, CSS and JavaScript
-   [H5P content](https://h5p.org/)

Please note this is an experimental feature. Therefore, copying and importing slides with external content is not yet available.
