This document provides guidance on writing introductions for papers. It states that introductions are important for making a good first impression and engaging the reader. A strong introduction should get the reader's attention, identify the specific topic, conceptualize the main argument, and explain how the paper is organized. It recommends starting with an interesting quote, story, or fact; stating the purpose clearly without saying "this paper is about"; and including a thesis statement at the end of the introductory paragraph. The introduction length can vary depending on the complexity of the topic and length of the overall paper.
