I'm confused about making a site tour. Is there any documentation?

Hi,
I'm not sure how I'm supposed to enter the url ID. Is this something I make up like:

http://domain.com/site_tour/groups or do I have to use a number for the ID?

And for each page's path, should it be written the same as the close/exit paths? I was going to use just plain old og for both of those. Do I make each page's path based on the url ID? I went to the Amberjack.org page too and forum but it's not clear what I'm suppposed to do within drupal.

Thanks for the help.
