+### Support KnockoutJS
+Include [knockout-sortable.js](knockout-sortable.js)
+
+```html
+<div data-bind="sortable: {foreach: yourObservableArray, options: {/* sortable options here */}}">
+	<!-- optional item template here -->
+</div>
+
+<div data-bind="draggable: {foreach: yourObservableArray, options: {/* sortable options here */}}">
+	<!-- optional item template here -->
+</div>
+```
+
+Using this bindingHandler sorts the observableArray when the user sorts the HTMLElements.
+
+The sortable/draggable bindingHandlers supports the same syntax as Knockouts built in [template](http://knockoutjs.com/documentation/template-binding.html) binding except for the `data` option, meaning that you could supply the name of a template or specify a separate templateEngine. The difference between the sortable and draggable handlers is that the draggable has the sortable `group` option set to `{pull:'clone',put: false}` and the `sort` option set to false by default (overridable).
+
+Other attributes are:
+*	options: an object that contains settings for the underlaying sortable, ie `group`,`handle`, events etc.
+*	collection: if your `foreach` array is a computed then you would supply the underlaying observableArray that you would like to sort here.
