title: including JavaScript SDK for facebook comment box
body: <p>What do I need to do include JavaScript SDK ,so that I am able to use the facebook code for comment box :</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&amp;appId=1xxxxx34xx26x0";
  fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));&lt;/script&gt;
  </code></pre>
  
  <p>and </p>
  
  <pre><code>&lt;div class="fb-comments" data-href="http://example.com" data-num-posts="2" data-width="470"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I looked at <a href="http://developers.facebook.com/docs/reference/javascript/" rel="nofollow"><strong>this</strong></a> page but I really haven't understood how to do this. I have hosted my website on google appengine which doesn't support php .I want to implement a comment box for my website.</p>
