−The EEPROM pins, which are used by the Pi to recognize more complicated Devices connected to the Pi
+The EEPROM pins,GPIO 0 1 (Pi pins 27, 28) which are used by the Pi to recognize more complicated Devices connected to the Pi. It is strongly suggested these pins are not used. But they do work at a pinch.
−And Pin 13 ( GPIO27) is used for a fan so if this is something you believe you need it is a good idea to leave this pin free.
+And Pin 13 ( GPIO27) is used for a fan by the zynthian-pwm-fan controller. A wonderful addition that turns a mosquito buzzing always on fan into a cleverly managed fan, that just gets it right and only works hard when it has to. So if this is something you believe you need it is a good idea to leave this pin free, althou' you can configure it. Such is choice.
Be aware that the I2C pins (pins 3,5) are used for all kinds of expansions and also the correct way to do this sort of encoder addition ( 23017 uses this, and a couple of other pins).

Depending on what you are trying to do other pins can be used, but it's wise to have an idea of what else was is used on your machine.

If you want to try out the simplest config use an USB Audio connection and you shouldn't have to worry.

+The following is an example that has worked, and below is another selection that has been proved.

+It would be nice to give an emphatic set up and have that identified in the config files.
+If so we will maintain the information here.
