BBPress Integration with Buddypress 1.1.3 and Wordpress Mu 2.9.1

Hello,

I am wondering if there is any tutorial on how to integrate bbpress with buddypress/wordpress mu because I have put the bbpress folder on the root of my wordpress install and when I go to the link, bbpress just says page not found (with the bbpress theme, and forum look), so there is no install. If anyone has any info, I'd be please if you can share!
