+## Extra
+
+Added functionality to fetch and display all repos for a user, to do so just call the plugin on the container and pass it a github username as part of its options object:
+
+```javascript
+$('.container').github( { username: 'timdouglas' } );
+```
+
+This will create all the divs automatically for you, if you want to give them extra classes, pass the elClass option with the username.
