+********************************************
+Testing the door lock only with Arduino Nano
+********************************************
+
+Currently, there is an option to test the door lock blueprint with no other hardware, as there are two other door lock types:
+#. led door lock
+#. led rotating door lock
+
+Both of them simply turn on the led light when the lock is locked/unlocked. 
+To use them, you need to build the doorlock as described in `build using west section <#alternative-way-of-building-the-software-using-west>`_. After cloning the project, enable other
+type of door lock in ``src/main.cpp`` (the name of classes are available in ``src/`` directory).
