Explaination on how to use library

[ChSt15]

I want to use the library on a board i already have with teensy 4.0 on pin 22. i Have some things hooked up to pins 4 and 8 so i dont want the library to send signals to those pins. I also only want to use the DShot sending commands without telemetry. How do i enable only the motors i need? and how do i control everything? I cant seem to wrap my head around what i need to get everything working and how the interface works

Seconded this. It seems to be the only source for arduino dshot on the internet but it's wrapped with such complexity it doesn't seem to work.
