Black Powder Epic Battles AW Guts & Glory Set question on assembling

Hey all! I recently got the Black Powder ACW Guts & Glory starter set. This is my first dip into Black Powder, coming from things like Warhammer 40K and Bolt Action but, I really like the epic scale and time periods that BP covers. I'm just wanting to confirm how this box was intended to be assembled. Is it supposed to be 3 regiments of infantry, 1 regiment of zouave, 1 regiment of cavalry, and 3 cannons for the Union? Then, 3 regiments of infantry, the skirmishers, dismounted cavalry, and also 3 cannons for the Confederates as pictured? Is that a fair match-up for these two armies?
