 ESP2866 is a fallback option and will be used if the build is for unsupported platform.
 
+#### Connecting the ESP2866 ####
+
+ESP module needs to be connected to RX and TX UART pins (+ power and ground) on your target board. That can be achieved using Grove shield or connected directly using jumper wires, please note that not all Arduino form factor boards have UART compatible with the Grove shiled.
