Yes, it's difficult to get started, but you can do it! Make a new map and lay the ground work first (like with forest base). Then make a layer or two and place items on the ground with layers. Then look and try the other stuff. I fooled around with it this way until I understood it.
Once you create a map, THEN you create a new location with the same exact name as the map. The type of location will be "map." Anyway, once you have the map location, you can click on a tab in the location and see that you can define boundaries. This means that the Player can cross from one map into another map automatically, unless you've closed the access tiles.
My first map is not connected to any other map. So the Player has to transport into another map when he leaves and enters the world.
For the world, I have 56 maps linked together by boundaries. I suggest that you make sure that the maps are square and of the same size if you link by boundaries.
Have at it!
