Usage is very simple. Simply add the Sassy Maps block to your page. You will be presented with a preview of available maps, simplly click the one you wish to use. It should be highlighted with a border.

Sassy Maps uses Google Maps V3 API. You will need to add an API key, it is free, and you can get a key here. 

The only other mandatory option to set is the map center. Simply enter an address, postcode, zip code or coordinates if you have them.
Optionally you may set a map marker using the same approach, or leave it blank for no marker.
Sassy Maps is limited to one use per page, and is disabled in edit mode.
