I'm hardly a novice when it comes to radio, but I must admit to being a bit overwhelmed when it comes to wspr.

What is the easiest way to become operational on this/these mode/modes?

Ideally, I'd like to have TX/RX capability, but I've also seen beacons and RX only/gateway/reporting stations as well.

I am well versed in Arduino, RPi and would prefer to make use of those over a dedicated PC. However, for the sake of getting operational, I'd be happy to use a PC.

Is there a SIMPLE how to get started in wspr page somewhere?
