Can someone give me a quick beginner rundown?

hi, so I just started like literally got the game yesterday just started playing today. I have no idea what I’m doing. I have no idea what anything does I have? No idea what I should be doing first I need simple instructions like super duper simple because I have no idea what to do in this game.

So if anyone can kinda ‘dumb-it-down’ it but it in… Simple terms. thank you. Ive had people give me a bunch of apparently good stuff but like I’m not at any sort good at this game yet
