mORMot Open Source

I have been looking for a PDF generator/editor for Delphi for a while now and all responses I have had point me to MORMOT2, I have downloaded and installed the full framework but I cannot seem to find a basic example of what should go in the USES clause for just using the PDF side f the framework.  I installed the full framework as I will be moving into Server-Client applications in the near future.

At the moment TPdfDocument comes up and an 'undeclared identifier'

POSSIBLY BEEN ASKED IN THE PAST BUT CANT SEEM TO FIND ANYTHING
