bbpress and child theme help

Hi, I’ve manage to get to setp 6 of the instruction on this website:
http://codex.bbpress.org/step-by-step-guide-to-creating-a-custom-bbpress-theme/
and managed to activate my child theme, which looks exactly like my parent theme.
I got stuck at copy “wp-content > plugins > bbpress > bbp-themes > bbp-twentyten” because the bbpress version 2.3.2 doesn’t have bbp-themes folder.
I just want to create a Forums page on my website but as of now I have no clue how to go about it. I heard creating a forums.php is one way, but since I’m so new to this I don’t know where to start.

Thanks
