+ * Let's take a look at how we can use `prism`, `Ticker`, and `val` from Theatre.js's Dataverse library
+ * to create a switch with state that is updated automatically,
+ * and is even stored in a Theatre.js object.
+ *
+ * Without going into the details of `prism`, `Ticker`, and `val`, note that by wrapping our `ToolsetConfig` in a prism, our
+ * ```ts
+ * ... .tapImmediate(Ticker.raf, (toolset) => {
+ *       set(toolset)
+ *     })
+ * ```
+ * code will be called whenever `val(obj.props.exampleProp)` changes (whenever the user clicks the switch and the `onChange` callback is called).
+ * This will ensure that our switch's value matches its state and is reflected in the UI via `set(toolset)`.
