Is there an actual Q & A page?

Sorry to be dense about this, but is there an actual Q & A page that I can edit, ie, add some text before the question/answers form and add a sidebar. I’m just not getting how this particular plugin works. I can see the page at my domain /questions/ask, but where is the actual page to edit?

By the way, I’m wanting to integrate this into an existing theme, not as a standalone them by itself.
