The skin.cfg file consists of three sections. As of yet only the keys info and author are supported. Here you may enter any information you like or find appropriate.
All rectangles are optional.
You may choose not to include some of them, just remove the appropriate line from the skin.cfg file. For your first steps in creating buddyPhone skins it may for example be easier to leave out the different xyzBandwidth buttons. The rectangle coordinates can easily be determined in most image editing applications. First set your image editors unit setup to pixels. Then move the mouse to the upper left corner of the rectangle.
