title: Laravel ardent with authenticatable user model
body: <p>May be simple question, but still I don't understand the concept behind it,</p>
  
  <p>I should use,</p>
  
  <pre><code>use LaravelArdent\Ardent\Ardent;
  
  class User extends Ardent {}
  </code></pre>
  
  <p>with <code>Authenticatable</code> class, now I have like this <code>class User extends Authenticatable {}</code></p>
  
  <p>How can I achieve this together?</p>
