The document discusses designing a web app called "Fucking do it" that allows users to track and manage messes. It outlines the design process including coming up with the concept, defining screens, designing screens, and adding HTML/CSS and live code. A design framework called Twitter Bootstrap is recommended to use for its quickness, ease of use, cross-browser friendliness, and the fact that it is better than having no design at all. The web app would allow listing and viewing all messes, reporting new messes, and marking messes as done.
