Hi, so to set up a map you will go into the plugin parameters and double click the "Maps" parameter, and then double click in the empty list to create a new map. You should see a parameter window pop up with all of the map settings, such as id, map images, and tracking settings. Remember the ID you set for your map.
For the map you want to display when there is no notetag on the map properties, type the same id in to your Default World Map parameter.
If you want a different map to display than what you have set as default while on certain maps in game, use the notetag in the map properties: <cgmzwm:id> so for example if your world map had id "world" you would put <cgmzwm:world>
