 To build the MoSh sample with Zephyr BT shell command support, use the :file:`-DDTC_OVERLAY_FILE=bt.overlay` and :file:`-DEXTRA_CONF_FILE=overlay-bt.conf` options.
 When running this configuration, you can perform BT scanning and advertising using the ``bt`` command.
 
-Compile as follows:
+You must program the *board controller* with the :ref:`bluetooth-hci-lpuart-sample` sample first, before programming the main controller with the :ref:`modem_shell_application` sample.
+Program the board controller as follows:
 
-.. code-block:: console
+1. Set the **SW10** switch, marked as *debug/prog*, in the **NRF52** position.
+   On nRF9160 DK board version 0.9.0 and earlier versions, the switch was called **SW5**.
+#. Build the :ref:`bluetooth-hci-lpuart-sample` sample for the ``nrf9160dk/nrf52840`` board target and program the board controller with it.

 The following example demonstrates how to use MoSh with two development kits, where one acts as a broadcaster and the other one as an observer.
