Asset Manager Extension HowTo?

Hello-

I’m trying to get the Asset Manager up and running but the README is
incredibly thin:

$ cat README
AssetsExtension

Description goes here

I found 2 good threads but couldn’t track down instructions.

So far I got the extension from:
http://www.keithbingman.com/svn/projects/radiant/extensions/assets/

And installed acts_as_attachment from:
http://weblog.techno-weenie.net/articles/acts_as_attachment

What’s next?

Thanks-
Michael
