How a put the home button on gasket?

The home button just sits loosely in the gasket. The sticky side of the gasket is on the same side as the touch surface of the home button. Just line everything up perfectly, (the wings of the home button go to the sides, and the square on the front of the home button, is perfectly square like a square, not a misaligned diamond) with the touch surface of the home button facing out towards the touch surface of the front screen, and press it into place from the back of the screen.
