 ## Custom Tags and Attributes
 
 Raptor Templates supports extending the language with custom tags and attributes. A custom tag or a custom attribute __must have at least one dash__ to indicate that is not part of the standard HTML grammar.

+## Async Taglib
+
+The async taglib allows portions of your template to be rendere asynchronously. An asynchronous fragment can be bound to a function that accepts an "args" objects and callback argument. When the data provider function completes and invokes the callback with the resulting data, the body of the async fragment is then rendered with the asynchronous data assigned to the specified variable. Asynchronous fragments allow parts of your page to render out-of-order while still providing the final HTML in the correct order.
+
+Example:
+
+```javascript
+template.render({
+        userProfileDataProvider: function(arg, callback) {
+            var userId = arg.userId;
+            userProfileService.getUserProfile(userId, callback);
+        }
+    }, ...);
+```
+
+```html
+<async-fragment data-providers="${data.userProfileDataProvider}"
+    var="userProfile"
+    arg-userId="${data.userId}">
+
+    <ul>
+        <li>
+            First name: ${userProfile.firstName}
