        <p>Either you have no routes setup yet, or you haven't selected one on the left.  To create a new JSON HTTP API route add a file to <code>api</code> with the file named after the route name you want.  If you want a socket handler then create a file in <code>socket</code> instead.  You can generate starter code each of these in the Djenterator.</p>
