 A jQuery plugin that adds cross-browser mouse wheel support.
 
-In order to use the plugin, simply bind the "mousewheel" event to an element. It also provides two helper methods called `mousewheel` and `unmousewheel` that act just like other event helper methods in jQuery. The event callback receives three extra arguments which are the normalized "deltas" of the mouse wheel.

 Here is an example of using both the bind and helper method syntax.
 
-    // using bind
-    $('#my_elem').bind('mousewheel', function(event, delta, deltaX, deltaY) {
-        console.log(delta, deltaX, deltaY);
-    });
+```js
+// using bind
+$('#my_elem').bind('mousewheel', function(event, delta, deltaX, deltaY) {
+    console.log(delta, deltaX, deltaY);
+});
 
-    // using the event helper
-    $('#my_elem').mousewheel(function(event, delta, deltaX, deltaY) {
-        console.log(delta, deltaX, deltaY);
-    });
+// using the event helper
+$('#my_elem').mousewheel(function(event, delta, deltaX, deltaY) {
+    console.log(delta, deltaX, deltaY);
+});
+```
