 ## Mutable<T> solution
 
 Mutable allows for easy getting/setting/updating.
 
 For example:
 
-snippet: mutable_example
+<!-- snippet: mutable_example -->
+<a id='snippet-mutable_example'></a>
+```java
+Mutable<String> i = new Mutable<>("Brian");
+Scheduler scheduler = new Scheduler(() -> i.get());
+scheduler.addEvent();

+scheduler.rsvp();
+i.set("Steve");
+scheduler.bookHotel();

 Will produce the following:
