+## Compiling and Uploading
+
+A Makefile is provided to compile and upload to the board. This Makefile uses:
+
+* [arduino-cli](https://github.com/arduino/arduino-cli) for compilation
+* `esptool.py` shipped with the arduino core for uploading (while this [issue](https://github.com/arduino/arduino-cli/issues/163) is not resolved)
