Using GPIO on a Pi-KVM is a feature designed for advanced users, so make sure you understand exactly what it is. -In the case of Pi-KVM, the general term GPIO refers not only to the physical interface of the [Raspberry Pi](https://www.raspberrypi.org/documentation/usage/gpio), +In the case of Pi-KVM, the general term GPIO refers not only to the [physical interface of the Raspberry Pi](https://www.raspberrypi.org/documentation/usage/gpio), but also to various plugins (for example, for [USB relays](http://vusb.wikidot.com/project:driver-less-usb-relays-hid-interface)) that can also be used transparently by emulating abstract GPIO API.
