Season the pork all over with salt, pepper, and any other seasonings you'd like, then place it in the slow cooker.
Cover with a lid and cook on low for about 8 hours, until it reaches an internal temperature of 190F.
When the pork is done cooking, remove it to a board, and let cool for at least 20 minutes before shredding with a fork.
Take the leftover liquid from the crockpot and strain it to remove any solids.
If you don't mind the fat, add the liquid back to the shredded pork and toss well. If you want to remove the excess fat, chill the liquid in an ice bath in the refrigerator for about 30 minutes until the fat solidifies, then discard, and pour the remaining liquid over the pork. Enjoy!
*Different salts vary in "saltiness," but I do about 1 tablespoon of kosher salt for a 4 to 5lb pork butt. If you're using table salt, cut the amount in half.Leftovers will keep in the fridge for 5-6 days, and can be frozen for up to two months.
