title: How to add an extension
body: <p>I am fairly new using the Forge Viewer and have started by created my <a href="https://developer.autodesk.com/en/docs/viewer/v2/tutorials/basic-application/" rel="nofollow noreferrer">Basic Application</a>.</p>
  
  <p>Now, I would like to try to add this <a href="https://github.com/Autodesk-Forge/forge-rcdb.nodejs/tree/master/src/client/viewer.components/Viewer.Extensions.Dynamic/Viewing.Extension.Showcase" rel="nofollow noreferrer">extension</a>. I did some searching and added this to my HTML:</p>
  
  <pre><code>forge.run
  (
      // divId
      'ForgeViewerContainer',
      // config
      {
          extensions:[
              './Viewer.Skybox'
              'Viewing.Extension.Showcase'
          ]
      },
  </code></pre>
  
  <p>Now I want to load the extension. I can't quite get the hang of it. Any help would be appreciated.</p>
  
  <p>Sorry for the basic question!</p>
