+On Raspberry Pi and on many clones the pins exposed on the GPIO belong
+to the first gpiochip. They can therefore be used on klipper simply by
 referring them with the name `gpio0..n`. However, there are cases in
 which the exposed pins belong to gpiochips other than the first. For
 example in the case of some OrangePi models or if a Port Expander is
