The document provides guidance on how to write an effective introduction for a formal paper. An introduction should attract the reader's attention with a hook, provide necessary background or definitions, and state the thesis clearly. The thesis should communicate the paper's significance and take an original position that others could challenge or oppose. An introduction typically includes a hook to engage the reader, a brief background if needed, and a clear thesis statement outlining the paper's argument or process. It should be concise and avoid long background details or definitions not essential to understanding the thesis. The goal is to attract and orient the reader to the central idea and purpose of the paper.
