 There are a number of reasons why we recommend you use Bower instead of the CDN:
 
-- The CDN does not host polymer.html which removes the ability for elements to import it.
+- The CDN does not host `polymer.html` which removes the ability for elements to import it.
 - There are many elements which are not hosted on the CDN so it might be tricky to include all of them in your project.
 - You will not be able to [Vulcanize your code](/articles/concatenating-web-components.html).
 
+For testing and reproducing bugs, you can link to the current versions of the `platform.js` 
+and `polymer.html` files on `polymer-project.org`:
+
+    <script src="//polymer-project.org/platform.js"></script>
+    <link rel="import" href="//polymer-project.org/components/polymer/polymer.html">
+
+(Many of the Core and Paper elements can also be found under `components`.)
+**Please do not these URLs in production applications.** They should only
+be used for testing.

 ### I see a bunch of XHRs making network requests. What gives? {#xhrrequests}
 
 One limitation of today's polyfills is that {{site.project_title}} aggressively uses XHR to shim HTML Imports. We're experimenting with packaging systems and build steps to reduce the cost of network requests. HTML imports are supported natively in Chrome 36 this API lands natively in browsers, where things will Just Work™. Resources load as they normally do, taking advantage of parallelism, browser caching, etc.
