Summary:
Help screen does not mention required step - add API key
Detailed Description:
As mentioned in bug 11075, this (excellent) module now requires a Google API
key. However there is no mention of this in the help screen. It would be useful
to include this step which is missing.
Suggest adding 2 new bullet points in "How do I use it" section.
Add new bullets before "Create a map":
- Apply for a a Google Maps API key: see
https://developers.google.com/maps/documentation/javascript/get-api-key
- Paste your key into the "Google API Key" field in the Preferences tab
