Thread:Extension talk:Maps/Can a custom layer be used instead of a mapping service?/reply (2)

I did not install it, I just asked the Wikia Community folks to turn the Extension on for my wiki. I do have a Layers: namespace, but other than that, I don't know what to do in order to make a layer that is compatible with this extension. According to the Versions page, I'm running MediaWiki 1.19.18 with Maps Extension 2.0.1. Any help or insight would be appreciated. :)
