How do I use ZenProfile?

I thought Ryan Davis' presentation at the Ruby Conference was great. It
was one of the best of the conference, but I was bum to see that much
of the cool usage information from the presentation was lost in movies
not contained in his slides. I tried to look for usage information on
ZenSpider, but couldn't find any.

I have installed the gem for ZenHacks and am now waiting for the
insight to put it to use.

Any help would be greatly appreciated.
