Breast feeding tips

I have been researching breast feeding consistently for days and it’s honestly driving me a little nuts. I keep seeing so many stories about dry cracked nipples and that led me to research exclusively pumping which is apparently even more challenging. Now I’m back at square one thinking I want to breastfeed. What tips do you have as far as a schedule? Do I feed on both sides? What if the baby doesn’t empty both sides during feeding ?
