Display forum'description on the front-end

Hello,

I would like to display on the front-end (over forum list on bbpress root page) the forum’s description (see here: http://i.imgur.com/o3c5iA1.png … to see what i’m speaking about).

I know there is a hook to put some content in this area “bbp_template_before_forums_index” but is there a function or a shortcode to get the forum’s description (http://i.imgur.com/o3c5iA1.png) ?

Thx
