Undermined! Pairadice City - Set up and how to play

About Undermined! Pairadice City, from BoardGameGeek:

Welcome to Pairadice City, where the ground is overflowing with treasure ready to be found. You're racing to be the first to uncover as many treasures as possible all while avoiding any perils and dealing with the antics of your fellow miners! Will you sell treasures you've found to fund future expeditions and stall your race to the finish? Or will you keep them, push on deeper into the mines and risk losing it all to secure your victory? -description from the designer
