title: How to get build logs of a binder session
body: <p>Binder hosted at www.mybinder.org is a service for launching Jupyter notebooks  online.</p>
  
  <ul>
  <li><p>When launching a notebook the  <code>Build logs</code> and a <code>nbviewer</code> preview are displayed.</p></li>
  <li><p>Once launched the Jupyter session is displayed.</p></li>
  </ul>
  
  <p>Is there a way to access the  <code>Build logs</code> after the Binder session as started?</p>
