In a small bowl combine the taco seasoning and salt.
Place the brisket into the slow cooker, then liberally sprinkle the taco/salt seasoning onto the entire brisket (top and bottom)
Add 1 cup of beef broth to the side of the crockpot then cover the crockpot with the lid.
Set the crockpot to the low setting for 7 hours.
Prepare the toppings and placed them into serving bowls then refrigerate them until it's time to serve.
Once the timer goes off on the crockpot, remove the brisket to a cutting board then shred the meat using two forks. (You can reserve a bit of broth or drain it depending on how dry the brisket is)
Warm the tortillas in a skillet and keep covered.
When it's time to serve, add the lime wedges and toppings onto a platter for easy taco building.
Place a small amount of brisket, onto the center of the tortilla then choose desired toppings.
