Help with scrolling

Unity Engine
1

I need help with making a GUI window and having a list of strings that will be added to during game play.
And as the list gets bigger and fills the window a scroll bar pops up and stays where the last messenge is. And you can scroll up and down to look at the strings.

Search the scripting reference for
GUI.BeginScrollView
GUI.EndScrollView

or

GUILayout.BeginScrollView
GUILayout.EndScrollView

Thanks for the help
