The Readme documentation, in the section Linux?, says that these are the steps to follow:

apt install python3-pip
pip3 install pyserial
apt install python-is-python3

However, I got an error when trying to follow those instructions. It seems Debian and Ubuntu (and potentially Fedora?) are not allowing the use of pip to directly install packages onto the system Python installation to make it less likely that one of those packages might break the main system installation. Here's the article I read about it: https://www.linuxuprising.com/2023/03/next-debianubuntu-releases-will-likely.html

Doing some more research I found a solution that worked for me and allows me to compile my sketches throught the Arduino IDE:

apt install python3-serial
