+### Building with low-power configuration
+
+You can build the example using the low-power configuration, which enables
+Thread's Sleepy End Device mode and disables debug features, such as the UART
+console or the **LED 1** usage.
+
+To build for the low-power configuration, run the following command with
+_build-target_ replaced with the build target name of the Nordic Semiconductor's
+kit you own (for example `nrf52840dk_nrf52840`):
+
+    $ west build -b build-target -- -DOVERLAY_CONFIG=overlay-low_power.conf
+
+For example, use the following command for `nrf52840dk_nrf52840`:
