You display the PDF. You can do this in presentation mode of Acrobat or another PDF viewer of your choice, or you can use a dedicated PDF presentation program such as keyJnote, which adds some nifty features useful especially for presentations (such as zooming in, spotlight, all-slides-preview, etc.).
Unfortunately, KeyJNote is currently unavailable, as Apple's lawyers have apparently started yapping about trademark infringement. (http://keyj.s2000.ws/?p=77) Hopefully it will come back soon under a new name (presumably not iOvercharge, since Apple no doubt owns that one). I'd like to try it.
