Sidebar Customization

In order to customize the Q&A plugin, do I copy the php files in the default-templates folder into the theme root or do I move the complete default-templates folder over to the theme?

/themes/buddyboss/default-templates/php files


/themes/buddyboss/php files

I'm trying to get the sidebars widgetized so that I can add information to the right sidebar area ... otherwise, maybe there is a way to do this and it isn't showing up in admin panel
