I Need Help With My Main Menu

So I've been working on my unity 2D platform game and I can't figure out how to make a main menu, I have my new seen all set up and i made three buttons one to send the player to the first scene (which I named Level1), I made the second to send the player to let the player quit the game, and the third button tosend the player to a More information Scene(Which i named MoreInfo). could someone make a C# script for me and explain how to use it for the main menu that I want to make? Also the first button is called "Play Game", the second is called "Quit game", and the third button "More Info". Please if someone could help me with this it would solve two of my biggest problems for my game. Like always, THANKS!
