Atticus is not ideal for low content books like yours quite yet, however it is *possible *to create them.
The easiest solution is to import a jpg or png file and use it to create a page template. Once you import your image and get the formatting and layout perfected once, you can turn it into a template and use that to Add a new "chapter", as we call it, but in your case it would simply be a new page. You would just need to repeat this for as many pages as you'd like in your book. You can also create a variety of templates, and add them as necessary.
I would recommend you size your images for the proper trim size for your book. This tutorial should help with that: https://www.atticus.io/calculate-image-size-for-print-and-ebooks/
