+The firmware is based on the [Spencer Library](https://github.com/CircuitMess/Spencer-Library). It is, along other required libraries, automatically installed when you install the CircuitMess ESP32 Arduino platform. More info on [CircuitMess/Arduino-Packages](https://github.com/CircuitMess/Arduino-Packages).
 
-Follow the instructions in the [README](https://github.com/CircuitMess/Spencer-Library/blob/master/README.md) on how to install the library, or just clone or download it into your Documents/Arduino/Libraries folder on Windows, or ~/Arduino/libraries folder on Linux. (NOTE: you will have to install some library dependencies.)
