 Polyfill Service - the lazy way
 
+Polyfills are only loaded when they are needed.  
+Initial 2Kb to polyfill a lot of Stuff.  
+
+Let's assume that your browser does not support the function "Element.prototype.toggleAttribute".
+```js
+> ['a','b','c'].at(-1); // accessing  [].at immediatel loads the polyfill
+> 'c'
+```
+
+
 # Ussage
 
 Add this script on the top of your page:
-
 ```html
 <script src="https://cdn.jsdelivr.net/gh/nuxodin/lazyfill@xxxxx/mod.min.js"></script>
 ```
+done!
+
+# How it works
+
+To every polyfillable property, the scripts adds a getter which synchronously loads the corresponding polyfill.
+Of course, we all know that blocking xhr-requests is not nice.  
+Therefore, the url to the script that should be added to the page is given in the console.
+
+# Help
+Any help is greatly appreciated.
