+### Option 2: Use CDN hosted FirebaseUI files
+
+If you would prefer to use a CDN instead of locally compiled FirebaseUI files, you can instead 
+locate the following in the `<head>` tag of `public/index.html` and `public/widget.html`:
+
+```html
+    <script src="dist/firebaseui.js"></script>

+Finally, ensure you are in the `demo/` folder (and not the root directory of FirebaseUI), and run:
