I create a new Screen Layout (workspace, desktop) to use when Compositing: 8-Nodes. and initialize this new default User setup used in all future tutorials. I also teach how to move the window around, what the starting nodes are and do (RenderLayer, Composite, Viewer) Backdrop, , how threads work in the noodle, rendering the composite. Also I talk about basic window management and splitting, and using the UV/Image Editor to view images/results.
