Hello Matt and welcome to Moodle 
I have to say though that Moodle does not use the actual wiki activity (documentation here: Wiki activity to create its documentation site; instead we use separate sites created with MediaWiki - so it is indeed standalone.

You could make a course on your Moodle site and add just one wiki to it - using the single activity course format. Assuming you want all users to edit the wiki then you could use self enrolment to the course and then once people have enrolled, they can edit the wiki.
