Have a look at this player aid
A 2nd worker only goes to the 4th player btw (the 2nd and 3rd always get just 1 extra worker).
Edit: The setup is more a reminder what you need. You have to also put the action card pile face down and reveal the top animal & goods cards of the 2 piles.
Make 2 equal piles for goods & animals (top card face up).
Place face up supply piles of silver, workers, 1&2 VPs, bonus, round and action cards (face down).
Setup display cards (1-6) in a column.
Players set up a project (3 cards max), storage and estate area using the appropriate cards.
Start with 1 silver, 1 good & 1 animal.
Deal 1 worker to the 2nd & 3rd player; the 4th player gets 2 workers.
Hope it makes sense.
