[Feedback] Missing docs/examples for "Emulate mouse, keyboard, and gamepad inputs" feature

[DatCaptainHorse]

Hello o/

As per issue title, I don't see any "nice" documentation or examples for the "Emulate mouse, keyboard, and gamepad inputs" feature advertised on the readme.

Is is possible to add one? Also would this still rely on real hardware, or would it be able to create a "virtual" input device?

InputPlumber works with a "CompositeDevice" model. Typically you attach one or more physical "source" devices and one or more virtual "target" devices together. The composite device configuration identifies which devices to grab and which devices to emulate.
