+# is not provided (it could be the case that an end-user is trying to build without the board connected), then the
+# target binary is not flashed. In the case of the MCUboot example, the "factory firmware" is saved and would require
+# manual transfer when the board is indeed connected. In either case, the demonstration step would be the only part
+# that requires manual intervention.
+#
+# Important: The tool assumes the target board and toolchain unless otherwise specified by the end-user. However,
+#            currently, the only board and toolchain supported are NRF52840_DK and GCC_ARM respectively.
