I have Copper Sulfate and vinegar, how do I copper plate a quarter?

I have everything I need, the power supply, alligator clips, beaker, Copper Sulfate, vinegar, the quarter, everything. What do I do, I think I mix the Copper Sulfate and the vinegar, and then attach both to the power supply, immerse in the solution, then I make sure they do not touch, turn on the power supply and wait. Is this correct/would you make any adjustments?
