BuddyPress.org

How do I add profile fields to buddypress profile I know how to add them to the sign up page and go to edit profile to fill them out and vview them but how do I add that data to the bbuddypress members page I see buddypress has its own bp members page seperate from the wp one
The one I want to put fields on that they fill oout has mentions and friends on it.. I think it’s the buddypress members page
