-## Desktop Notification Support
-
-Desktop notifications allow asynchronous communication of events without
-forcing you to react to a notification immediately. Their appearance
-and specific functionality vary across platforms. They typically disappear
-automatically after a short delay, but their content is often stored in some
-manner that allows you to access past notifications.
-
-[Growl][] was an early notification system implementation for OS X and Windows,
-hence, the name of Mocha's `--growl` option.
-
-Once enabled, when your root suite completes test execution, a desktop
-notification should appear informing you whether your tests passed or failed.
-
-### Node-based notifications
-
-In order to use desktop notifications with the command-line interface (CLI),
-you **must** first install some platform-specific prerequisite software.
-Instructions for doing so can be found [here][mocha-wiki-growl].
-
-Enable Mocha's desktop notifications as follows:
-
-```bash
-$ mocha --growl
-```
-
-### Browser-based notifications
-
-Web notification support is being made available for current versions of
-modern browsers. Ensure your browser version supports both
-[promises][caniuse-promises] and [web notifications][caniuse-notifications].
-As the Notification API evolved over time, **do not expect** the minimum
-possible browser version to necessarily work.
-
-Enable Mocha's web notifications with a slight modification to your
-client-side mocha HTML. Add a call to `mocha.growl()` prior to running your
-tests as shown below:
