 You may instantiate [`ButtonManager`](https://github.com/GTNewHorizons/Navigator/blob/master/src/main/java/com/gtnewhorizons/navigator/api/model/buttons/ButtonManager.java) to create your own logical button.

 Congratulations, you have finished the logical implementation of your custom map layer! Now it is time for the visual integration. This example is provided for JourneyMap, but you might as well take a look at the other possibilities. Since you already implemented the button as a first step, you will need to follow it up with an implementation of `JMRenderStep`. This class will receive an instance of `MyLocation` and perform the actual rendering.
