How to drop marketplace modules into a campaign?

Ive looked all over for this info.  I bought the double dungeon pack off of the marketplace to drop into an existing campaign, but im at a loss as to how to do so.  Is there a tutorial on this im missing?

You select a module as the base for a new campaign. Without the pro feature transmogrifier, you can't transfer non-character objects between games. If you want to use these modules in an ongoing campaign, I would recommend using the character vault to transfer your PC's characters into the module's game and then transfer them back to your permanent campaign once you've finished running through it.

Pro members also have access to the  Transmogrifier to transfer handouts, pages, etc between campaigns. 

Thanks guys, that makes sense.
