  *
+ * @section CAPI_WATCH_APP_MODULE_FEATURE Related Features
+ * This API is related with the following features:
+ * - http://tizen.org/feature/watch_app
+ * It is recommended to design feature related codes in your application for reliability.
+ * You can check if a device supports the related features for this API by using @ref CAPI_SYSTEM_SYSTEM_INFO_MODULE, thereby controlling the procedure of your application.
+ * To ensure your application is only running on the device with specific features, please define the features in your manifest file using the manifest editor in the SDK.
+ * More details on featuring your application can be found from <a href="https://developer.tizen.org/development/tizen-studio/native-tools/configuring-your-app/manifest-text-editor#feature"><b>Feature Element</b>.</a>
+ *
  * @subsection CAPI_WATCH_APP_MODULE_STATE_CHANGE_EVENT Registering Callbacks for Application State Change Events
  * The state change events for Tizen watch application is similar to the Tizen UI applications. See the @ref CAPI_APPLICATION_MODULE.
  * In Tizen watch application, an ambient changed event is added to support ambient mode. Time tick related events are also added to provide an exact time tick for the watch application.
