Simply start a new Microsoft PowerPoint presentation. Make sure that the slide show is set to be browsed at a kiosk. To do this click Slide Show > Set Up Show in your Microsoft PowerPoint menu. Now set the Show type to Browsed at a kiosk. Also make sure that all slides in your presentation are advancing automatically. Go to your slide and click Slide Show > Slide Transition. Now set the Advance slide option to Automatically and set time property. Make sure that this is done for all slides in your presentation.

Now you can add your content to the presentation and finally make it available to ShowPoint by copying or saving this presentation into the shared presentation folder on your file server.

All running ShowPoint clients will detect the new presentation and start the slide show on the local computers.

Select the presentation you want to update from your shared presentation folder and open the presentation. Now you can update content, create and delete slides in the presentation. If you now save the presentation all connected and running ShowPoint clients will detect the change and copy the new presentation locally and start the slide show with the newest information.
