This document provides guidance on how to be a good reviewer for academic papers and the review process. It discusses the mechanics of reviewing, including being contacted by editors, meeting deadlines, and providing a recommendation. It outlines characteristics of good and bad reviews, such as being constructive, clear, and concise in feedback, and avoiding rejecting papers solely based on personal interests. The document recommends structuring reviews by summarizing the paper, providing compliments, then discussing major issues over 1-2 pages followed by less important questions. Reviewers should read papers multiple times and in layers to fully assess the arguments and design.
