This document discusses using SketchFlow for rapid application prototyping. It notes that the typical agency workflow involves multiple briefing and rebriefing stages before conceptualization and delivery. SketchFlow streamlines this process by allowing designers to import files, create fully functional prototypes without code, add states, and get feedback directly in the browser through interaction and commenting. The document encourages getting started with SketchFlow by downloading the necessary software and assets and provides contact information for support.
