+
+## Use case
+
+Allows you to customize a graphic with a multilayer symbol. For example, you may want more customizable symbols than those that are provided with the API to display a unique representation of a landmark.
+
+## How to use the sample
+
+The sample loads with multilayer symbols displayed for points, polylines, and polygons.
+
+## How it works
+
+1. Create multilayer symbols for each predefined 2D simple symbol style.
+    * For multilayer point symbols, use the `MultilayerPointSymbol` constructor.
+    * For multilayer polyline symbols, use the `MultilayerPolylineSymbol` constructor.
+    * For multilayer polygon symbols, use the `MultilayerPolygonSymbol` constructor.
+2. Create `Graphic`s by passing in a `Geometry` and the associated multilayer symbol.
+3. Add graphics to the graphics overlay with `graphicsOverlay.getGraphics.add(graphic)`
+
