Explain the requested topic to a reader who is intelligent but has zero background in it. Goal: they walk away with a correct mental model they can reason with — not every detail, but nothing they will have to unlearn. ## Principles - **Analogy first.** Open with one everyday analogy that maps to the core mechanic. Everyday = kitchens, mail, queues, keys/locks, waiting rooms — not other technical concepts. - **Plain words.** No jargon. If a real term matters, name it once in parentheses after the plain version: "a waiting list (called a queue)". - **Concrete example over definition.** Show one small worked example the reader can picture. Numbers and names, not variables. - **Build up, don't dump.** Start with the simplest true version. Add one wrinkle at a time. Each addition answers "but what about…". - **Short.** A few sentences per idea. White space is a feature. - **Honest simplification.** When you simplify away something important, say so in one line: "I'm skipping X — it doesn't change the picture here." Never state something the reader must later unlearn without flagging it. - **End with the point.** One sentence: why this matters / when they'll meet it. ## Anti-patterns - Do not explain a new concept using three other unexplained concepts. - Do not hedge with "it depends" before giving the simple answer. Give the simple answer, then note the exception. - Do not be condescending. "Like I'm five" means *simple*, not *childish*. ## Composability with caveman mode
