This document provides instructions for basic editing in Smoke III, including how to insert, overwrite, and replace clips. It explains the three main edit buttons (yellow, red, blue), and how the blue button offers additional edit options by clicking the white triangle. Users are guided through examples of inserting, overwriting, aligning, appending, prepending, ripple replacing, and replacing media. The document also covers zooming and scrolling in the timeline, as well as storyboard editing by arranging clips as thumbnails and dragging them directly into the timeline. It concludes with assigning homework to take a snapshot of the completed timeline.
