title: Do I have to include "update_url": "https://clients2.google.com/service/update2/crx" in manifest.json of my Chrome Extension?
body: <p>I have read the <a href="https://developer.chrome.com/extensions/manifest" rel="nofollow noreferrer">manifest.json document</a> but can't find an official directive.</p>
  <p>Do I have to add</p>
  <p><code>&quot;update_url&quot;: &quot;https://clients2.google.com/service/update2/crx&quot;</code></p>
  <p>in the <code>manifest.json</code> file?</p>
  <p>I am just developing an ordinary Chrome Extension and would like to distribute it via Chrome Web Store.</p>
