Loading/using my first module

Hello! Sorry if this was answered before, but I can't seem to find the answer. I bought the Sunless Citadel to play with my friends. We have all played before, but now that I am GMing, I don't know how to download a PDF of the background information, etc, of the book.  This is an "Add on" module, but looks like it can be played on its own and I can buy the rest later. So, I started the game, added the add-ons, and now I see the art, etc, in the game... but where is a PDF of the book, the stuff I need to read?  Just a little lost here! Thanks a ton! I have GMed before, but not from a module.  Beau 

I have not used R20 modules, but I believe there should be a handout or two in your JOURNAL tab with that information.

Ah HA! Brilliant, thanks a ton!  Beau 

Is there a PDF associated with the bundle? I have been looking for one as well to have on hand during game time so I don't need to constantly scroll the handouts.

Turtle. Most modules do not have a pdf to download. All the information is usually contained in the handouts. With that said, some of the early modules did have a pdf as the handouts were rather limited back then.
