+## Shimming-polyfills
+
+This library is written using some of the new ES5/ES6 features. If you have
+to support Non-standard-compliant browsers like Internet Explorer, you can
+polyfill some of the missing features with the following alternatives:
+
+**Using [es6-shim](https://github.com/paulmillr/es6-shim)**
+
+```html
+<!-- put this script FIRST, before all other scripts -->
+<script src="https://cdnjs.cloudflare.com/ajax/libs/es6-shim/0.35.3/es6-shim.min.js"></script>
+```
+
+**Using [polyfill.io](https://polyfill.io/v2/docs/)**
+
+```html
+<!-- put this script FIRST, before all other scripts -->
+<script src="https://cdn.polyfill.io/v2/polyfill.min.js"></script>
+```
+
+[Polyfill.io](https://polyfill.io/v2/docs/examples) reads the `User-Agent`
+header of each request and returns the polyfills that are suitable for the
+requesting browser.
+
+If you want to request specific polyfills, you can pass a query parameter
+to the url, for example:
+
+```html
+<!--[if IE]>
+<script src="https://polyfill.io/v2/polyfill.min.js?features=default-3.3&flags=always"></script>
+<![endif]-->
+```
+
+Read the list of available features:
+[Features and Browsers Supported](https://polyfill.io/v2/docs/features/).
