title: Google Chrome extensions autoupdate
body: <p>As Google says <a href="http://developer.chrome.com/extensions/autoupdate.html" rel="nofollow">here</a> you don't have to specify something if you host your Chrome app in Google Servers. But why all the extensions I analysed had this code in their manifest.json. Should I also write this code in my chrome extensions manifest?</p>
  
  <pre><code>"update_url": "http://clients2.google.com/service/update2/crx",
  </code></pre>
  
  <p>As I said I will upload and share my app using chrome web store</p>
