如何整合Wordpress和bbPress？

Can anyone explain me how to integrate Wordpress 3.0.1 and the bbPress 1.0.I just want to install bbPress with my previous Wordpress site (Url : mysite.com).I just want to install it on mysite.com/forum . I just tried doing it by creating a folder and installing bbPress there,( I skipped the wordpress integration ). When I tried to log onto the bbPress,it just throwed a hell lot of warnings saying function deprecated. I can not figure out why this all is happening.Is this due to some version problem?Can anyone explain me how to integrate Wordpres
