How do I align text to a corner of the screen?

I’m going to make some simple debug information, and I want it to be displayed as text in the bottom left corner of the screen. I just want to know how to always keep it aligned there, even when I adjust the resolution? Thanks.

make your rect start at 0 x screenheight - rect height.
ie:
Rect blah = new Rect( 0, Screen.height - 20, 120, 20 )
