[Zope] Product integration - please help!

Hi everybody! I am a beginner with products. I am trying to integrate the Boring sample product into Zope. There are 5 source (.py and .dtml) files. Could anybody explain me how to integrate it into Zope?? Also, where could I find out about troubleshooting for importing products? When I try to import a .ZEXP file I constantly get this "The object MyProduct does not support this operation" Hope to hear from you.... Lena
