 Flashing an application to STM32F429I-DISC1
 -------------------------------------------
 
+The board is configured to be flashed using west OpenOCD runner.
+Alternatively, you can use `STM32CubeProgrammer`_ (after installing it) using the ``--runner``
+(or ``-r``) option:
+
+.. code-block:: console
+
+   $ west flash --runner stm32cubeprogrammer

 First, connect the STM32F429I-DISC1 Discovery kit to your host computer using
 the USB port to prepare it for flashing. Then build and flash your application.
