How to win a Queen and King vs King endgame?

If we just start out by checking the King, it won't work, we need to mate him, not check him. First, you need to put your Queen in a "Knight's jump away" from your opponent's King and keep it that way, no matter where the opponent's King goes, you must keep your Queen a "Knight's jump away" from you you opponent's King. When your opponent's King touches the corner, your Queen must stop, and then you can bring your King into the game. But you don't put your King inside the fence(as shown in the game below), and the last step is you bring you Queen one square diagonal from the corner to checkmate your opponent's King(as shown below). Here is how you do that:
