readme-writer

Description

Generate a production-quality README.md from code, a short description, or an existing bad README. Adapts structure to the project type: library, CLI tool, web app, API, or data pipeline. No filler, no fluff — just the README a maintainer would actually want.

Use when

• "write a README for this"
• "my README is bad, rewrite it"
• "generate docs for this project"
• "I need a README"
• Any project without a README, or with a placeholder/skeleton README

Input

Provide one or more of:

• The project's source code (or key files)
• A short description of what it does
• The existing README (if rewriting)

Optionally specify:

• Project type: library / CLI / web app / REST API / data pipeline / other
• Primary language/framework
• Target audience: end users / developers / both
• License
• Whether to include badges (CI, npm, PyPI, NuGet, etc.)

Output format

Outputs a complete, ready-to-paste README.md in this structure (sections omitted if not applicable):

# [Project Name]

[One-line description — what it is and what it does]

[Badges if requested: CI status, version, license, downloads]

## Features
[3–6 bullet points — concrete capabilities, not marketing copy]

## Quick Start
[Minimal working example — copy-paste runnable in under 60 seconds]

## Installation
[Package manager commands for all relevant platforms]

## Usage
[The most common use cases with code examples]

## API Reference
[For libraries: key classes, functions, parameters, return types]
[For CLIs: flags, subcommands, environment variables]

## Configuration
[Environment variables, config file format, defaults]

## Examples
[1–3 real-world examples beyond quick start]

## Contributing
[How to run locally, run tests, submit PRs]

## License
[License name and link]

Writing rules

• First line after the title: one sentence, no jargon, a 10-year-old could understand
• Quick Start must be runnable — no "replace with your actual values" placeholders unless unavoidable
• API Reference uses the actual function/class names from the code
• No phrases: "seamlessly", "powerful", "robust", "leveraging", "game-changer", "easy to use"
• If something requires setup steps, number them — don't paragraph it
• Code blocks have language tags (python, bash, ```json)
• Never write "TODO" or leave blank sections — omit sections that don't apply

Project type adaptations

Library

Include: Features, Installation, Quick Start, API Reference, Examples, Contributing Skip: Deployment, Environment Variables (unless it's config)

CLI tool

Include: Installation, Usage (with all flags), Examples, Configuration Skip: API Reference

Web app / SaaS

Include: Features, Quick Start (local dev), Installation, Configuration (env vars), Deployment, Contributing Skip: API Reference (unless it exposes one)

REST API

Include: Base URL, Authentication, Endpoints (method, path, params, response), Examples Format: Use code blocks showing curl or example request/response JSON

Data pipeline

Include: What data flows in / out, How to run, Configuration, Output format Skip: Contributing (unless open source)

Self-improvement instructions

After each README generated, note what information was missing from the input that required assumptions. After 20 READMEs, surface the top 3 things developers forget to include.
