I recommend starting with their downloadable 'A Study in Scarlet' and building off of that. It shouldn't matter where you place the Hype assets, as long as they are within the
books folder and you reference the Hype animation from one of the parts which you have defined in the
contents section of
book.json. The Book folder behaves like a regular website, so make sure that your references include the folder name of where your Hype JS file is located.
Are you able to share an example?
