Profile Visitors Tracker

I'm trying to make it possible for my Buddypress users to see which users have visited their profile. I've found a plugin called YD Profile Visitor Tracker and it seems to be what I'm looking for. The problem is I don't understand how to add it to the theme. I'd like to place it on the Buddypress privacy page. I've read that I need to insert a template tag somewhere, but I'm not sure where. Any ideas?
