-Before you build a sample, you must configure the following Wi-Fi credentials in the :file:`overlay-nrf700x.conf` file:
-
-* :kconfig:option:`CONFIG_WIFI_CREDENTIALS_STATIC_SSID` - Network name (SSID)
-* :kconfig:option:`CONFIG_WIFI_CREDENTIALS_STATIC_PASSWORD` - Password
-* :kconfig:option:`CONFIG_WIFI_CREDENTIALS_STATIC_TYPE` - Security type (Optional)

-.. note::
- You can also use ``menuconfig`` to configure Wi-Fi credentials.

-See :ref:`zephyr:menuconfig` in the Zephyr documentation for instructions on how to run ``menuconfig``.

 Building and running
 ********************
 
 To build the sample with |VSC|, follow the steps listed on the `How to build an application`_ page in the |nRFVSC| documentation.
 See :ref:`building` for other building scenarios, :ref:`programming` for programming steps, and :ref:`testing` for general information about testing and debugging in the |NCS|.
 
-An overlay file, ``overlay-nrf700x.conf`` is provided to all Zephyr samples, which configures the sample to run with the Wi-Fi driver.
+A :ref:`Wi-Fi snippet <zephyr:snippet-wifi-ipv4>` configuration is provided to all Zephyr samples, which configures the sample to run with the Wi-Fi driver.
 
 To build Zephyr samples for the nRF7002 DK, use the ``nrf7002dk/nrf5340/cpuapp`` board target.
 The following is an example of the CLI command:
 
 .. code-block:: console
 
- west build -b nrf7002dk/nrf5340/cpuapp -- -DEXTRA_CONF_FILE=overlay-nrf700x.conf
+ west build -b nrf7002dk/nrf5340/cpuapp -S wifi-ipv4
 
 To build for the nRF7002 EK with nRF5340 DK, use the ``nrf5340dk/nrf5340/cpuapp`` board target with the ``SHIELD`` CMake option set to ``nrf7002ek``.
 The following is an example of the CLI command:
 
 .. code-block:: console
 
- west build -b nrf5340dk/nrf5340/cpuapp -- -DSHIELD=nrf7002ek -DEXTRA_CONF_FILE=overlay-nrf700x.conf
+ west build -b nrf5340dk/nrf5340/cpuapp -S wifi-ipv4 -- -DSHIELD=nrf7002ek
