The book Oh Crap Potty Training (it's a PDF you can buy online) was really helpful for us in figuring out what to do. We started potty training each of our boys on the "early" side (around 19 months). They both caught on quickly; our oldest is now 3, the younger is 20 months. The 20-month-old has occasional accidents, but they're occasional - maybe 2-3 per week.
I don't know how old your child is, but the tough thing about lots of modern potty-training advice is to wait until your child is 3 or even 4 years old, and there will be all sorts of "scientific" or "psychological" evidence presented for why your child should be pooping himself when he's old enough to ride a bike. The Oh Crap Potty Training book is nice because, even though it mentions what to do with older kids, the focus really is on getting kids trained before age two.
Several people have advocated for having some sort of underwear on the kid while potty training, but I disagree with that, at least for the first few days or so. Kids who have been in diapers their whole life so far don't mind feeling wet when they pee or having their poop smushed up against them - gross as it is, to them it's normal. You don't want them to think of underwear as "just another diaper." With both of our boys, we've done lots of naked time, especially over the tile floor, but yes, there are occasional leaks on the carpet, and it's not the end of the world. I'd much rather clean up a few leaks in the living room but be done with diapers. :-)
