Stupid Powerpoint question

My boss wants a slide that will introduce new information when he clicks on it. Should I build separate slides that add the information progressively, or is it a macroey thing on one slide?

Never done this before; hate PPT.

EDIT:
I built it as 5 separate slides, so he can run the whole thing as a slideshow. We don't typically hand out booklets, so that's not a problem. Am waiting on feedback from him now.

Thanks for the hand!
