 Notice that *clickMe.getValue() doesn't return a String, it returns a *CompletableFuture<String>.
 This is because retrieving something from the DOM requires some communication with the browser and
 will take some time - and we don't want to block while we wait.
 
+This example is a little pointless since we're just setting the value and then immediately reading it, but it becomes
+a lot more useful once you know how to attach event listeners to DOM elements.

 This allows us to take advantage of Kotlin's `coroutines <https://kotlinlang.org/docs/reference/coroutines/basics.html>`_
-functionality to make this fairly seamless to the programmer (using *GlobalScope.launch* and *await()*.
