 INTRODUCTION
 ============
+
+- transmits control data using ESP-NOW transmission protocol
+- in a provided tutorial data being sent from transmitter to the sender is sufficient for defining RC car speed and direction; added functionality is possible by expanding the code
+- core functionality includes: transmitter and receiver
+- at the same time, the ending look and functionality of RC car can vary as there are many areas for freedom
