+To match the HTML5 and and drop spec, links and images are implicitly treated as draggable. You can turn off this behavior by setting 'requireExplicitDraggable' to 'true'.  This way, only elements with the `draggable` attribute set to `true` will be draggable.
+
+```html
+<script>
+var iosDragDropShim = { requireExplicitDraggable: true }
+</script>
+<script src="vendor/ios-drag-drop.js"></script>
+```
+
 With npm:
 ```shell
 npm install --save drag-drop-webkit-mobile
