Since we have to install the wiring tool from GitHub I think they meant to say from the command line you’ll likely need to:
Scroll to install git version instructions:
sudo apt install git
git clone [GitHub - libre-computer-project/libretech-wiring-tool]
cd libretech-wiring-tool
sudo ./install.sh
That will install the version of the wiring tool that lets us set the temp control fan.
From there we just set it up as posted:
sudo ldto enable pwm-a
sudo ldto enable pwm-a-fan
sudo ldto merge pwm-a
sudo ldto merge pwm-a-fan
sudo ldto merge pwm-a-fan-auto
sudo reboot
