An outline organizes a paper in a hierarchical structure, breaking it down into parts. It is helpful to write an outline before starting a paper to organize one's thoughts. The basic format uses alternating numbers and letters to indicate levels of importance. The example outline is about the development of Japanese theater, with the thesis stated in section I. Sections II through V cover early theatrical forms, Noh theater, Kabuki, and Bunraku puppet theater. Each section analyzes authors, props, themes, and audience. The conclusion restates the thesis without new material.
