How To Play - 7 WONDERS: LEADERS

About 7 Wonders: Leaders, from BoardGameGeek:

7 Wonders: Leaders adds 42 new cards to the base game of 7 Wonders, comprising four new guilds, one new wonder card, and 36 (+1 blank) white "Leader" cards. At the start of the game, each player takes a hand of four leaders and may play one at the start of each of the three Ages. Unlike the standard cards, leaders cost money (not resources). The expansion comes with a new Wonder-the ancient city of Rome-and contains 6-gold tokens made of cardboard for more efficient money-management.
