how do you make saewoojeot, salted shrimp?

https://en.wikipedia.org/wiki/Saewoojeot

does anyone actually have a recipe for making this at home? it seems like it’s just tiny shrimps salted. how much salt for how much shrimp? how do you prepare the shrimp prior to salting? how long does it take to ferment?

or don’t people make this anymore at home?
