How to save game progress?

Question

Unity

I'm making a game with similar mechanics as in Pokey Ball, you need to implement saving the game, that is, when you exit the game at a certain level, the next time you enter the game, the game starts from the level from which the player left the game last time. I read that you can use PlayerPrefs, but I don’t understand how to implement it.
