How do you play Dead by Daylight? Help

I bought this game a few years ago, played like 2 matches and quit. Mostly because I didn’t really understand what the goal of the game was. There’s a bunch of people on the team and a boss hunting, but what exactly are you supposed to do?

The game looks really good, but I don’t have the patience to sit and read tutorials anymore lol

If there’s anyone out there who has the patience to help out a newbie, I’ll be streaming tonight.
