It's a good idea to start with the quiet cue and make sure your dog knows it before you ever move on to the bark cue. This is especially helpful if your dog already likes to bark a lot.

Somewhere they are likely to bark
Don't shout at your dog to be quiet—it just sounds like you're barking along with them.
Keep your training sessions positive and upbeat.
Be consistent so you do not confuse your dog. Everyone in your family must apply the training methods every time your dog barks inappropriately. You can't let your dog get away with inappropriate barking some times and not others.

Create a situation that will cause your dog to bark. The best method is to have a friend ring the doorbell or knock on the door. Or, you may be able to get your dog very excited in order to cause barking. Sometimes seeing another dog can bring on barking.
When your dog barks, briefly acknowledge it by checking for the source (look out the window or door, go to your dog). Then, get their attention (try squeaking a toy squeaker or hold up a toy).
When the barking, give your dog the toy or treat.
Repeat steps 1-3 but gradually wait for slightly longer periods of silence each time before giving the treat.
Choose one simple word for the quiet command. This word should also be easy to remember and used consistently. Good choices: "enough," "quiet," or "shhhh." And put your fingers to your lips
Once your dog has remained quiet a few times, add in the cue. While your dog is barking, say your quiet command in a firm, audible and upbeat voice while holding up the reward. Give your dog the reward when the barking stops.
Once you have done the initial training, ensure you practice the "quiet" cue frequently. You can do this anytime they bark
