title: ngdoc documentation for controller
body: <p>I am to new to code documentation and trying to document my angular application with grunt-ngdocs. </p>
  
  <p>I cloned a working example from: <a href="https://github.com/m7r/grunt-ngdocs-example" rel="noreferrer">https://github.com/m7r/grunt-ngdocs-example</a></p>
  
  <p>The given example lacks a documented controller so I added my own documented controller with this code:</p>
  
  <pre><code> /**
    * @ngdoc controller
    * @name rfx.controller:testCtrl
    * @description 
    * Description of controller.
    */
   .controller('testCtrl', function() {
   });
  </code></pre>
  
  <p>When I am trying to build a documentation by running grunt from the command line I get the following error message:</p>
  
  <pre class="lang-none prettyprint-override"><code>Warning: Don't know how to format @ngdoc: controller Use --force to continue.
  </code></pre>
  
  <p>How do I fix this? I read this guide <a href="http://www.shristitechlabs.com/adding-automatic-documentation-for-angularjs-apps/" rel="noreferrer">http://www.shristitechlabs.com/adding-automatic-documentation-for-angularjs-apps/</a> and I can't figure out why do I keep getting error message if I try to document a controller :( Thanks for any help!</p>
