+## Usage
+
+### Translate
+```js
+$('#FancyElement').transition(
+{
+  translate: [2, 20, -1] // performs translate3d if capable
+},
+{
+  easing: 'ease', // whatever the css transition-timing-function accepts
+  duration: 1000, // one sec (its in millisecond)
+},
+function()
+{
+  // All done
+  console.log($(this)); // #FancyElement
+});
+```
+
+### Opacity
+```js
+$('#FancyElement').transition(
+{
+  opacity: 0.1 // no JS stepping here, native CSS transition
+});
+```
+
+## Customization
+Take a look at the Opacity handler for how to build your own, to support any CSS property you want
+transitioned (if supported by browser).
