How to add main menu, game over and local high scoreboard screen

Unity Engine
1

I am adding on to the cooking with unity 3 minute game. When I die I want the game over screen to pop up. Then a button to go to the high score screen. Finally a button to return to a main menu screen to start the game again. This is my first game so i was hoping to get these important features ironed out early in my career.

Or alternatively, check out some of the GUI options available on the Asset Store such as NGUI.

So this should teach me how to do all the things I listed above?
