+### Basic Setup with ES6 module loader
+
+The polyfill can also be loaded using the native ES6 module loader available in
+the recent browsers versions.
+
+Be aware that the polyfill module does not export the `browser` API object,
+but defines the `browser` object in the global namespace (i.e. `window`).

+  </head>
+  <!-- ... -->
+</html>
+```
+
+```javascript
+// In background.js (loaded after browser-polyfill.js) the `browser`
+// API object is already defined and provides the promise-based APIs.
