To start off, you have to find a village (Obviously). When you do, you won't find normal long-nosed villagers, but villagers that look more like players. As I said before, they all have randomized skin, hair, eyes, and outfits, plus their own names, so there are over a thousand different variations!

Interacting with a villager will open up a menu with a bunch of different options, allowing you to talk with them or trade like normal. There are five different personality types a villager can have, changing what they say and affecting how much your relationship goes up.

By talking, your relationship will increase and new options will become available, such as allowing them to follow you. (At the moment, they can only follow you if you're in survival mode.) You can also increase your relationship with a villager by giving them gifts, currently only food. Just interact with them while holding the food you want to give them, and they'll take it. By giving them their favorite food, which you can learn by talking, the relationship will go up even further.

Along with replacing villagers, wandering traders are now replaced. They are randomized like the villagers, excluding their clothing. As of now you can only talk and trade, but more interactions are planned in the future.

Witches have been changed as well. They're now neutral, and won't attack you unless you attack them first. You will be able to talk to them in  later update.
