Summarize the following:
Crate training is the first step in potty training. Choose a crate with enough room for your dog to turn around comfortably. However, it shouldn't have so much room that he could use the bathroom in one corner and sleep in another. If your puppy learns to associate his crate with using the bathroom, he'll resist going into the crate to lay or sleep.  In the first few weeks, expect accidents in the crate even if it's the right size for the puppy. Don't lose your patience, though! He's still learning. If your puppy is a larger breed, consider buying a crate with adjustable barriers that can be removed as the dog grows. Place the crate in a busy room in the house, where people gather often. The den or family room is a good location for crate training. Leave the crate door open so the puppy can explore it at his own pace, and treat him whenever he goes into the crate.  After he's grown used to the crate, start closing the door and leaving him in it for longer periods of time. Crate him at night and anytime you aren’t home or able to watch him. You can move the crate between rooms, bringing it into the bedroom with you at night, for example. But always make sure it's somewhere your dog feels safe. Take him to that same spot every time you take him out. If he associates going to the bathroom with a very specific place, he'll be less likely to have accidents in other places. It'll also make clean-up easier in the future because you'll know where he likes to go. Minimize how much time he plays outside during the first 2-4 weeks of potty training. Playing with the dog outside in the middle of his potty training will confuse him about what he should do when he goes outside. When he's mastered potty-training, you can start spending more playtime outside with him. Choose a specific word or phrase to serve command him to use the bathroom. "Bathroom" or "Go potty" are examples. When you take him outside, use that same phrase and the same tone of voice every time he goes to the bathroom. If your puppy uses the bathroom after you give the command, praise him with a lot of excitement and a treat. You might also choose a separate command specific to encouraging your dog to defecate. Young puppies need to defecate more often, so teaching a dog to associate a specific command with defecating can be useful. This isn't a punishment, but a training tool. If your puppy doesn’t use the bathroom within a few minutes of you giving the command, put him in his crate for 5-10 minutes. The dog may whine or cry when confined to the crate, but don’t let them out.–It will confuse the learning process.  After 5-10 minutes have passed, take him back outside to use the bathroom and give the command again. Repeat the process until he makes an attempt to use the bathroom after you give the command. When he finally uses the bathroom, repeat the command and reward him with lots of praise and a treat, then let him back into the house to play.

Summary:
Buy a crate for your dog. Get your puppy used to the crate. Assign a regular bathroom spot. Limit the puppy's outdoor time. Encourage your puppy to use the bathroom on command. Crate the puppy if he doesn't potty on command.
