Where is the Q&A Outputted to?

After finding out that the support plugin has no front end support I looked at he Q&A instead.
I can see nothing in the docs about where the plugin is outputted to so that visitors can see it.
In the admin section there was a settings message that referred to [Q&A] so I assumed this was a short code. I added this to a page but there was nothing displayed.
Please can you tell me how this is meant to work?
