Intended use cases?

I think there needs to be more examples and use cases on the documentation, at least references to them

I’m pretty sure that on the mathematical / statistical academia there are plenty of uses related to this for research or big-data optimization; however I also see a lot of uses on deduplication and reprocessing of information since it tells you when something is for sure not already loaded, but I don’t know if it’s worth it to do it this way versus a more common Redis EXISTS command
