@@ -4,3 +4,7 @@ This folder contains nanoMODBUS examples for Arduino.
 To build and load a sketch with the Arduino IDE, copy `nanomodbus.c` and `nanomodbus.h` inside its folder.
 
 `client-rtu` and `server-rtu` are meant to be used with two Arduinos connected via their TX0/RX0 serial pins.
+
+If you have [arduino-cli](https://github.com/arduino/arduino-cli) installed, you can run
+`examples/arduino/compile-examples.sh` from the top-level nanoMODBUS directory to compile the examples.
+They will be available in the `build` folder.
