configuration file

[sz3bbyla]

helo sir, I compile your code, and try using it on proxmox 8 with IT8625E AS6602T . look there are working , but I'm not an programmer so I try to ask you if you can explain how to do a configuration file and where to put in system to be loaded by default on boot
the examples I try are working but forword I don't have any clue how to use it
I am not an programmer
for example:
the state of hdd led to be green - online, green blink - when is used r/w , red - when is fail, and where mast add this config in system to be loaded on boot
fan control - is an example you show which must be add in /etc/fancontrol . I don't try this but I don't understand how is read by system and if is loaded on boot
will be nice to understand for noob like me
