Set default value of a string in settings?

Hey guys,
Does anyone know how to set the default value of a string in settings? Like when the user starts it the first time?

 

Lol, I just need this info. Like in the settings app in iPhone. Is it creating a new key called DefaultValue?

Oh, and did you join just to tell me this?

 

Okay, I found out. You have to create a new string called DefaultValue and set what you want the default value to be.
