Main Menu question

Hi, I have decided that in my game instead of having a main menu with options I will just have it show who made it (credits) and then show the name of the game and go straight to the game.

So my question is how would I make credits and would I need a timer to go to the first level, if so what is the script.

function Start () {
yield WaitForSeconds (2);
Application.LoadLevel (Application.loadedLevel + 1);
}
Attach that javascript to any object in the credits scene then after the desired amount of seconds, it will load the next scene in the build settings/
