PMA.slidebox is intuitive enough, but your content may not be. Sometimes you wish you could add some default in that big empty screen-area on the left when the website is launched for the first time.

Look e.g. at what Larry did:

As it turns out, Larry actually just made a simple HTML page, describing his own slide collection. The page behind it can be loaded separately, and is really just plain HTML like any other page on the web (this means that you could also make it as complex as you wish).

It suffices to look up the folder structure where PMA.slidebox's webserver is running. Then, rename your webpage into intro.htm and place it into a /extra_data/ folder.

The result is immediate, as PMA.slidebox automatically picks up the available new content and renders it accordingly.
