README Template

Overview

A README is the front door of your project. It is the first thing developers see on GitHub, npm, PyPI, or Docker Hub. A well-structured README reduces onboarding friction, answers common questions, and sets expectations for contributors.

This template provides a battle-tested structure you can copy, adapt, and ship in minutes.

When to Use

Use this template when:

• Starting a new open-source project
• Documenting an internal library or tool
• Publishing a package to a public registry
• Handing off a project to another team

Solution

Copy the template below and replace the [bracketed] placeholders:

# [Project Name]

[![License](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)

> [One-line description of what this project does.]

## Table of Contents

- [Overview](#overview)
- [Installation](#installation)
- [Usage](#usage)
- [API Reference](#api-reference)
- [Contributing](#contributing)
- [License](#license)

## Overview

[2-3 paragraphs explaining what the project does, why it exists, and who should use it.]

## Explanation

Each section serves a specific purpose:

- **Badges**: Instantly communicate build status, version, and license
- **One-liner**: Hook the reader in under 10 seconds
- **Table of Contents**: Essential for long READMEs; auto-generated on GitHub
- **Installation**: Lower the barrier to first success; include copy-paste commands
- **Usage**: Show a minimal working example before explaining edge cases
- **API Reference**: Link to detailed docs; keep the README scannable
- **Contributing**: Set expectations for PRs, issues, and code style
- **License**: Protects both authors and users legally

## Variants

| Project Type | Sections to Add | Sections to Skip |
|-------------|-----------------|------------------|
| **Library / SDK** | API Reference, Changelog | Screenshots |
| **CLI Tool** | Commands, Flags, Config | Architecture |
| **Web App** | Screenshots, Demo link, Deploy | API Reference |
| **Internal Tool** | Onboarding, Internal Slack channel | License, Contributing |

## Best Practices

- **Keep the first 100 lines scannable** — most readers never scroll past the fold
- **Use a demo GIF or screenshot** — visual proof beats paragraphs
- **Link, don't inline** — detailed docs belong in `/docs`, not the README
- **Update the TOC** — stale TOCs frustrate readers; use `doctoc` or auto-generate
- **Add a troubleshooting section** — collect the top 3 issues from your issue tracker
- **Include a changelog link** — users need to know what changed between versions

## Common Mistakes

- **No installation instructions** — assume the reader has zero context
- **Missing prerequisites** — "it works on my machine" syndrome
- **Giant blocks of text** — break into sections, lists, and tables
- **Outdated examples** — broken code examples erode trust immediately
- **No license** — legally blocks usage and contribution
- **Copy-paste from another project** — stale links and wrong project names

## Frequently Asked Questions

**Q: How long should a README be?**
A: As short as possible while answering: What is this? How do I install it? How do I use it? Where do I get help?

**Q: Should I include a Table of Contents?**
A: Yes, if the README exceeds 300 lines. GitHub auto-generates one from H2 headings, but a manual TOC is more flexible.

**Q: Can I use HTML in a README?**
A: Yes, GitHub Flavored Markdown supports a subset of HTML. Use it sparingly for layout (e.g., centering badges) but prefer Markdown for content.
