Geolocation API key

Hi: I completed the install, but, for some reason, the Geolocation plugin doesn’t have a field for an API key - though the plugin seems to be working. Could someone direct me to information on Geolocation API keys? Thanks

As of version 3.0, the Geolocation plugin uses Open Street Maps instead of Google, so the previous notices about the API key are no longer relevant.

Thanks. Simple enough!
