You can easily create slide shows using the [[Navigation]] macro.
For a new presentation, start on a new page - we use HelpOnSlideShows (this page) as an example.
For your convenience, there is a SlideShowTemplate - use it!
Put [[Navigation(slideshow)]] on top of that page (looks like you see above) - that creates a link to toggle between slide show and wiki mode, and a link to start the slide show.
Refer to your slides with numbered sub-page links putting some code like that on your top page:
* ["/000 Introduction"] * ["/100 Creating the slides"] * ... * ["/900 Last but not least: Running your presentation."] * ../SlideShowHandOutTemplate
Leave some numbers free in between - just for that case you need to insert additional slides later.
Don't use too long page titles - you will see that they look bad (at least in wiki mode due to wrapping of the wiki page title).
This will look like that:
