+In order to build the example with no diagnostic features like UART console or
+application logs, which should result in significantly smaller binary, run the
+following commands:
+
+ # Delete the build directory to make sure that no settings are cached
+ $ rm -rf build/
+
+ # Build the example using release config overlay
+ $ west build -b nrf52840dk_nrf52840 -- -DOVERLAY_CONFIG=third_party/connectedhomeip/config/nrfconnect/release.conf
