Texture 2D importer

How do I get to this screen:
http://docs.unity3d.com/Documentation/Components/class-Texture2D.html

I’ve been looking for it for some time now.
What I want to do is UV map a cube but I haven’t found a thread that gives a step by step process of how to do that.

I was searching for this just last night for awhile and finally found it. Click on ‘Texture Type’ and choose ‘Advanced’. I really wish that was on the Texture documentation pages.

Basically what I figured out is that when you drag a 2D image into the Project and click on it you get to this in the Inspector. I guess one part that was confusing me is that they took the words (Texture Importer) out.
As far as creating UV maps go, I guess you can’t easily figure out what the UV map looks like in Unity, you have to open up a 3D program to get it. Correct me if I’m wrong.
