Put Oats, Brown Sugar, Butter, Salt, and Water into Instant Pot. Stir.
Close lid and make sure the vent is set to "sealing." Press the Manual or Pressure Cook button and adjust the timer to 12 minutes. Instant Pot will pressurize then the countdown timer will begin.
After the timer reaches zero, DO NOT release the steam valve yet. Let it "naturally release" it's pressure for 10-12 minutes. Then release the remaining steam by turning the pressure valve to "venting."
Once steam has escaped, remove the lid. Stir oatmeal until desired consistency then serve in individual bowls with dried cranberries and slivered almonds. (or whatever toppings you like.) Clean up is a breeze! Enjoy!
