+### Dismissing
 
-## Examples
+Using the alert JavaScript plugin, it's possible to dismiss any alert inline. Here's how:
+
+- Be sure you've loaded the alert plugin, or the compiled Bootstrap JavaScript.
+- Add a dismiss button and the `.alert-dismissible` class, which adds extra padding to the right of the alert and positions the `.close` button.
+- On the dismiss button, add the `data-dismiss="alert"` attribute, which triggers the JavaScript functionality. Be sure to use the `<button>` element with it for proper behavior across all devices.
+- To animate alerts when dismissing them, be sure to add the `.fade` and `.in` classes.
