Can someone describe how this is done in non-PI specific terms?

Just to clarify: You want a how-to, right? You understand the theory of how it works?

@Charles Hagen has a guide on his website. It is written for PI, but it should translate to alternatives like Siril. Method 2 might be more straightforward if you're unfamiliar with the Siril equivalents of the PI processes mentioned in Method 1.
