Trying to put bike chain back on mtb... prob with gears?

i had a kink in my bike chain. instead of just putting the back wheel back on and sorting it'self out that way, i foolishly took the back little cogs off and manually unkinked it. now i don't know remember how the chain goes back on. pictures clear ones showing the chain direction would really help!!!!! i want to go out for a bike ride today but now i'm stuck
