 This is a simple application to configure the static libraries for the ESP32 Arduino core.
 It allows the user to select the targets to compile, change the configuration options and compile the libraries.
 
+Requires Python 3.9 or later.

 The application is built using the "textual" library, which is a Python library for building text-based user interfaces.
 
 Note that this application still needs the requirements from esp32-arduino-lib-builder to be installed.
