The order
Both engines off. Red lead to the positive terminal of the flat battery, then the other red end to the positive of the good battery. Black lead to the negative of the good battery, then the other black end to a bare metal earth point on the flat car's engine block — not to its negative terminal.
That last step is the one people skip. A battery vents hydrogen, and the final connection is the one that sparks. You want that spark away from the battery.
Then
Start the good car and let it run for a minute or two. Start the flat car. Remove the leads in exactly the reverse order. Keep the flat car running and drive it for a decent stretch, not five minutes.
What a successful jump does not tell you
It does not tell you the battery is fine. It tells you there was enough left to accept a boost. A battery that needs a jump twice is a battery that needs testing, and the test is free.
