As we also have been in contact via email, I'd like to channel our communication via email to ensure efficiency and keep in email contact. Here just a quick answer if someone else has the same question:
You can either work with our Image Recognition feature to recognize images / pages of a manual or magazin. If the pages a very 'text heavy' you can work with our Plugins API feature, that allows you to combine our SDK with a text recognition (OCR) engine (as our SDK is not optimized to recognize text)
The best way to start is to check out the sample app which comes with the SDK download package together with the respective documentation section.
Each section includes a set-up guide, which helps you set up your project. In your case it sounds like you intend to work with 2D image recognition and we do offer several samples around this feature.
Thx and greetings
