Place pork in the Instant Pot.
Add salt to season.
Add 1 cup of water to the pork.
Lock the lid, move valve to "sealing," select "Manual," and adjust time to 90 minutes.
When it beeps, use a natural release (NR) to allow the pressure to come down on its own.
After the pin has dropped (pressure has fully released), drain half the liquid from the pork and shred with a fork.
Add your favorite barbeque sauce, and enjoy on a hamburger bun, or lettuce leaves for a carb-free alternative!
