Resource manager

I'm trying to find out more about the resource manager to figure out if it's worth anything to me and our site. Where can I find the ultimate guide in how to set it up on my Xenforo demo?
Thanks for the input but that doesn't tell me how to set it up. I see lots of sites with awesome usage of the resource manager but in my demo set up I i.e. can not even make a rating of a resource.
I've finally figured out what was missing in the permission settings to make it work.
Is the resource plugin working with the latest version of Xenforo? I assume it is but just want to be sure.
