I recommend following the more tutorial-based instructions you're given at first. You don't have to follow a lot of them, but they're a good way to get started. Isabelle will give you some tasks that you can do to get you started on the basics of planting and selling stuff. Your villagers will probably give you tips on the game as well. If you don't know where to start, starting with that is a good idea.
You can also explore a bit and find things to do. Become familiar with the shops, things like announcement board, Re-Tail, etc.. It'll make it easier to understand how things work more quickly.
If you want to just take your time to discover things on your own, that's perfectly fine and a lot of fun. If you want a more planned playing style and don't mind finding out what's ahead, you can read up a bit on the things you can unlock and the villagers you can have, so you can set yourself bigger goals.
There isn't a right or wrong way to play this game. As long as you're not ruining things for other players, you should play in whatever way feels more enjoyable to you. Remember that it's also normal that you might not know about all the features when you're starting out, and that's fine! Knowing some of the basics can be helpful (I wish I'd known about plot resetting when I started!) but it can also be fun to play with the challenge of not being sure about all the features in the game.
