                    <p>In this example, we have set up an instance of AutoComplete. By using the
                    debug build of AutoComplete source code, we are able to instantiate a
                    LogReader on this page and read the messages generated from the component.
                    In order to place the LogReader in a convenient spot, we pass in a custom
                    bottom value into its constructor.</p>
