This is necessary because the <code>Lookup</code> class does a single lookup and discover step - it does not register with discovered lookup services. Thus, if a Blitz instance isn't registered beforehand, it will not be found (I'll fix this in a future release!).</p> + +<p>We are now ready to run the example.
