 Finally, add your layer name to publishers in `config/parameters.yaml`. You can create a new topic or add to existing topics.
 
 ```yaml
   plugin_example: # Topic name
-    layers: [ 'elevation', 'example_layer' ]
+    layers: [ 'elevation', 'example_layer', 'example_layer_large' ]
     basic_layers: [ 'example_layer' ]
     fps: 1.0        # The plugin is called with this fps.
