How to add an intro screen?

Depending on the kind of user experience you want, there are a number of way to do this. The easiest would be to use the roParagraph screen type to just display a couple lines / paragraphs of text with the help information you want. A more custom way to do it would be to use roScreen and the 2DAPI to render text and images:

You can also do similar things wtih roImageCanvas:
