README Creator Write a README that reads as a shop window, not a wiki. IS: writing or rewriting README.md for the person deciding whether to use the project, with the project type driving which capability sections earn a place and where the file will render (GitHub only, or also a registry page) driving image and badge choices. IS NOT: polishing the prose of a README that already covers the project, or a multi page docs site (use docs writing ); AGENTS.md or CLAUDE.md agent instruction files (use agents md ); fixing the install or first run experience the README describes (use dx audit ); marketing copy for a landing page (use copywriting ). The reader Someone arrived from a search result, a registry listing, or a profile page. They have about fifteen seconds and one question: is this worth my time? Every line either answers that or gets cut. They are not a contributor. Nothing about the build pipeline, the workspace layout, the release process, or the coding standards helps them decide, so none of it belongs here. This deliberately departs from standard readme and Make a README, which require Contributing , add a table of contents past 100 lines, and hold that too long beats too short. Do not drift back to those defaults: contributor content moves to CONTRIBUTING.md or AGENTS.md , and length follows what the reader needs. Reference Files File Read when references/section templates.md Phase 3: markup for each spine section, the capability section menu, and per type notes references/badges and shields.md Phase 4: only once Phase 1 has found a registry listing (npm, crates.io, PyPI, VS Code Marketplace, skills.sh) references/quality checklist.md Phase 5: score before declaring done Voice Check for a profile from the external ghostwriter skill before drafting: ${GHOSTWRITER HOME: ~/.config/ghostwriter}/readme.md . When one exists it owns the register, the spelling convention, and any house style markup (header block, badge colours, footer credit), and it wins every conflict with this skill. Follow it; do not restate it here. With no profile, default to terse second person imperative, no emoji, no exclamation marks, and concrete numbers over adjectives. Workflow Copy this checklist to track progress: Phase 1: Detect project type and render targets Read the manifest ( package.json , Cargo.toml , pyproject.toml , go.mod ) for name, description, license, scripts, bin , "private" , and repository . Read the existing README if rewriting. Scan the top level layout. Classify into exactly one type. First matching row wins, top to bottom: Type Decisive signal Skill bundle skills/ dir of SKILL.md files Monorepo workspace config ( turbo.json , pnpm workspace.yaml , workspaces) CLI tool bin field, src/cli. , or commander/yargs/clap dep Framework plugin/middleware architecture, config API, documented extension points Library / package main / exports set, no bin , src/index. entry Web app framework config ( next.config. , vite.config. ); no publish A monorepo is not a project type for README purposes. It is a delivery mechanism. Ask what a stranger installs or visits, then write the README for that: a repo whose apps/cli publishes to npm gets a CLI README at the root, not a workspaces table. The workspace layout goes in AGENTS.md . If two types still fit (a CLI that also exports an API, a framework published as a library), pick how most users consume it and fold the secondary role into one extra section. Then record where the file renders. A "private": true manifest or no registry listing means GitHub only. A published package also renders on npmjs.com, PyPI, or crates.io, which changes image URLs and earns badges (Phase 4 and the Gotchas). Ask the user only what code cannot reveal: What problem does this solve (the "why" behind the tagline)? Any section to force in or leave out? If unreachable, infer the "why" from the manifest and code, note the assumption in your summary, and proceed rather than block. Phase 2: Fix the spine, then choose capability sections Use this house spine where applicable. A hosted app can lead with its live URL instead of an install command; do not invent installation for a product consumed in the browser: 1. Header block (title, tagline, plain second line, badges if registry listed) 2. Demo (only when a live URL exists) 3. Install 4. Quickstart 5. License Between Quickstart and License go the capability sections: two to four, chosen from the menu in references/section templates.md . Four is a ceiling because a fifth section is almost always contributor content wearing a reader facing heading; when a fifth genuinely serves the reader, say why in your summary rather than silently adding it. Canonical heading names keep a set of repos consistent: Install , Quickstart , Demo , License . Not Installation , Getting Started , Quick start , Quick Start , Licence . Sentence case throughout, so Browser support and not Browser Support . The audience gate. Before writing any section, ask whether it helps someone deciding to use the project or only someone changing it. Contributor content goes to CONTRIBUTING.md or AGENTS.md (the destination table is in references/section templates.md ), and the README keeps at most a one line pointer. When no destination file exists, create it: deleting load bearing setup notes is a worse outcome than a slightly long README. Phase 3: Write sections Copy each section's skeleton from references/section templates.md , fill it, then apply the per type notes at the end of that file. These rules hold across every type: Title is the display name with spaces and capitals ("React Vello", not react vello ), linked to the live site when one exists. Tagline sits directly below with no heading, roughly 8 to 16 words, and says what the project does rather than what it is. Starting with the project's own name wastes the reader's first three words on something they just read in the H1. Second line is one plain sentence on what you actually do with it. Install is the single fastest command, copied from the manifest name field (never from the old README, which may predate a rename). One command, not a four tab npm/pnpm/yarn/bun matrix; anyone who prefers another package manager can translate npm install . Quickstart is the shortest complete thing that produces visible output. It keeps its full length even when that makes it the longest block in the file, because a truncated example fails only after the reader has pasted it. Every code block runs as is after copy paste: no pseudocode, no placeholder imports, no foo , bar , my app , or your name here . Use real ports, real branch names, real hex colours. Length follows need. Most land between 40 and 90 lines; a CLI with real flag tables earns 120. Past about 130 the overflow is a docs site or docs/ folder, linked from the README. for sections; only where genuinely parallel variants need separating inside one section, such as a CLI's install modes. Phase 4: Add badges Skip unless Phase 1 found a registry listing. Unpublished apps and internal monorepos get the header block with no badge row. Registry listings include skills.sh for a skill bundle, which serves an install count badge endpoint; the repo's own README uses it. When badges apply, load references/badges and shields.md . Default to two, version and license (installs and license for a skill bundle), in one style and one colour scheme so a set of repos looks like one set. A CI badge pointing at a workflow that never fires renders as a permanent failure, and a stars badge repeats a number already on the page. Phase 5: Validate Use references/quality checklist.md to check the consumer path and house conventions. Report runnable example and link/render results; a self score is not rendering evidence. Attach these render checks alongside the pass count. Each must return nothing: The checklist's Automatic Fail list is the hard gate: missing description, missing install, leftover boilerplate, a code example that cannot run, or a section that only serves contributors. Any of these means not done, regardless of score. Rewriting a published package's README, say in the summary that npmjs.com and PyPI show the README from the last publish, so the page changes only after the next release. Gotchas The blank lines inside <div align="center" are load bearing. CommonMark treats <div as an HTML block that runs until the next blank line, so Title on the line directly after the tag renders as literal Title . Same for the <p align="center" badge row and the closing </div . A relative image path ( .github/assets/demo.png ) renders on GitHub and 404s on npmjs.com and PyPI, which serve the README off repo. For a published package, point src at https://raw.githubusercontent.com/{owner}/{repo}/main/.github/assets/demo.png ; the file still lives in the repo. Off repo image hosts rot. GitHub proxies every external image through camo so an http:// URL loads today, but the host disappearing takes the screenshot with it. Commit images under .github/assets/ . A dark/light logo uses <picture with two <source media="(prefers color scheme: ...)" lines and an <img fallback. The gh dark mode only URL fragments are deprecated. PyPI strips <source and shows only the fallback, so make the fallback the light version. [!NOTE] alerts (also TIP , IMPORTANT , WARNING , CAUTION ) render on GitHub, npmjs.com, and crates.io. PyPI shows a literal [!NOTE] inside a grey blockquote. At most one per README, reserved for the thing that breaks installs; a README of callouts reads as a changelog. https://img.shields.io/github/license/{owner}/{repo} reads the repository's detected license. With no LICENSE file it renders license: not identified , which is worse than no badge. Check the file exists before adding the badge. The most common rewrite failure is a published package whose README was written for the person maintaining it. Symptom: the first heading is Workspaces or the install step is git clone . The fix is not trimming, it is writing for a different reader. A library README with a git clone Getting Started, or an app README with registry badges, means the type was guessed wrong in Phase 1 and sends readers down a dead path. Reclassify before editing prose. Confirm the package exists under the name you are about to publish in the install line: npm view {{name}} version (or cargo search , pip index versions ). A README pointing at an unpublished or renamed package fails the reader on line one. Rewriting several repos at once tempts you to guess install commands. Cite the manifest bin entry or script you drew each one from, and paste test a sample. Never ship a default scaffold README (create next app, create vite): replace it wholesale; readers treat it as abandoned. Feature bullets use Name: what it does. with a colon. A spaced hyphen ( Name what it does. ) reads as a stand in for an em dash and fails the house style. A Features section that restates the tagline is noise. Name it for what the reader gets ( Modes , What you can do , Keyboard shortcuts ) so each bullet has to add a capability.
