+It is common to want some data in the template to be available
 on an element.  `{{data name}}` allows you to save the
 context so it can later be retrieved by [can.data] or
-`$.fn.data`. For example,
+`$.fn.data`. 
 
-The template:
+<a class="jsbin-embed" href="http://jsbin.com/juxem/7/embed?html,js,output">JS Bin</a><script src="http://static.jsbin.com/js/embed.js"></script>
 
-    <ul>
-      <li id="person" {{data 'person'}}>{{name}}</li>
-    </ul>
+### Getting more specific
 
-Rendered with:
-
-    document.body.appendChild(
-      can.stache(template,{ person: { name: 'Austin' } });
-
-Retrieve the person data back with:
-
-    $("#person").data("person")
+By passing a key name as the second argument to the data helper, you can specify which data is used: `{{data name key}}`.
