Blender 2.5.3 Interface - Materials

I installed 2.5.3 and I cant find how to add material, or change material color to the basic cube mesh. Where is material interface now?

If anyone has link to 2.5.3 startup guide that would be awesome. All I found was 2.5.3 new advanced features, and all basic tutorials are for older versions.

In the buttons panel on the right hand side gointo the material button at the top (the tool tips tell you). You can add material slots at the top of the panel with the +/- buttons. Mouse click on the colour boxes to change the colour. The settings are pretty self explainetary if you’ve used previous versions of blender (agian use the tool tips)
