 Please note that these functions return the ``esp_netif`` handle, i.e. a pointer to a network interface object allocated and
 configured with default settings, which as a consequence, means that:
 
-* The created object has to be destroyed if a network de-initialization is provided by an application. The de-initialization should be performed in the two steps:
-    - :cpp:func:`esp_wifi_clear_default_wifi_driver_and_handlers()` -- To unregister default wifi handlers and detach the created object from the wifi
-    - :cpp:func:`esp_netif_destroy()` -- To destroy the ``esp_netif`` object.
+* The created object has to be destroyed if a network de-initialization is provided by an application using :cpp:func:`esp_netif_destroy_default_wifi()`.
 * These *default* interfaces must not be created multiple times, unless the created handle is deleted using :cpp:func:`esp_netif_destroy()`.
 * When using Wifi in ``AP+STA`` mode, both these interfaces has to be created.
