name	crafting-readme-files
description	Craft professional README.md files for GitHub open source projects. Generates hero sections, installation instructions, feature tables, and architecture diagrams. Use when creating or revising a README, documenting a CLI tool, library, or open source project, or when user asks about README structure, badges, or project documentation.

Crafting README.md Files for GitHub

Core insight: A README is a sales pitch, onboarding guide, and reference manual compressed into one document. Lead with value, prove with examples, document with precision.

Why This Matters

Most READMEs fail because they:

• Bury the value proposition under installation steps
• Explain what the tool IS instead of what problem it SOLVES
• Lack concrete examples (abstract descriptions don't sell)
• Miss the "quick escape hatch" for impatient users (curl one-liner)
• Don't show how it compares to alternatives

Great READMEs convert scanners into users in under 60 seconds.

THE EXACT PROMPT — README Revision

Read the current README.md and dramatically revise it following this structure:

1. Hero section: illustration + badges + one-liner description + curl install
2. TL;DR: "The Problem" + "The Solution" + "Why Use X?" feature table
3. Quick example showing the tool in action (5-10 commands)
4. Design philosophy (3-5 principles with explanations)
5. Comparison table vs alternatives
6. Installation (curl one-liner, package managers, from source)
7. Quick start (numbered steps, copy-paste ready)
8. Command reference (every command with examples)
9. Configuration (full config file example with comments)
10. Architecture diagram (ASCII art showing data flow)
11. Troubleshooting (common errors with fixes)
12. Limitations (honest about what it doesn't do)
13. FAQ (anticipate user questions)

Make it comprehensive but scannable. Use tables for comparisons.
Show, don't tell. Every claim should have a concrete example.
Use ultrathink.

<h3>Quick Install</h3>

```bash
curl -fsSL https://raw.githubusercontent.com/user/repo/main/install.sh | bash

Or build from source:

cargo install --git https://github.com/user/repo.git

```

TL;DR Section

## TL;DR

**The Problem**: [Specific pain point in 1-2 sentences. Be concrete.]

**The Solution**: [What this tool does to solve it. Action-oriented.]

### Why Use tool-name?

| Feature | What It Does |
|---------|--------------|
| **Feature 1** | Concrete benefit, not abstract capability |
| **Feature 2** | Another specific value proposition |
| **Feature 3** | Quantify when possible (e.g., "<10ms search") |

Quick Example

### Quick Example

```bash
# Initialize (one-time setup)
$ tool init

# Core operation
$ tool do-thing --flag value

# See results
$ tool show results

# The killer feature
$ tool magic --auto

### Comparison Table

```markdown
## How tool-name Compares

| Feature | tool-name | Alternative A | Alternative B | Manual |
|---------|-----------|---------------|---------------|--------|
| Feature 1 | ✅ Full support | ⚠️ Partial | ❌ None | ❌ |
| Feature 2 | ✅ <10ms | 🐢 ~500ms | ✅ Fast | N/A |
| Setup time | ✅ ~10 seconds | ❌ Hours | ⚠️ Minutes | ❌ |

**When to use tool-name:**
- Bullet point of ideal use case
- Another use case

**When tool-name might not be ideal:**
- Honest limitation
- Another case where alternatives win

Installation Section

## Installation

### Quick Install (Recommended)

```bash
curl -fsSL https://raw.githubusercontent.com/user/repo/main/install.sh | bash

With options:

# Auto-update PATH
curl -fsSL https://... | bash -s -- --easy-mode

# Specific version
curl -fsSL https://... | bash -s -- --version v1.0.0

# System-wide (requires sudo)
curl -fsSL https://... | sudo bash -s -- --system

Package Managers

# macOS/Linux (Homebrew)
brew install user/tap/tool

# Windows (Scoop)
scoop bucket add user https://github.com/user/scoop-bucket
scoop install tool

From Source

git clone https://github.com/user/repo.git
cd repo
cargo build --release
cp target/release/tool ~/.local/bin/

### Command Reference Pattern

## Critical Rules

1. **Lead with value, not installation** — TL;DR before Quick Start
2. **Curl one-liner above the fold** — Impatient users escape hatch
3. **Every feature claim needs an example** — Show, don't tell
4. **Comparison tables beat prose** — Scannable > readable
5. **Be honest about limitations** — Builds trust, saves support time
6. **Multiple installation paths** — curl, package manager, source
7. **Architecture diagrams for complex tools** — ASCII art is fine
8. **Troubleshooting section is mandatory** — Top 5 errors with fixes

---

## Anti-Patterns (Avoid)

| Anti-Pattern | Why Bad | Fix |
|--------------|---------|-----|
| Installation-first README | Buries value proposition | Lead with TL;DR |
| "This is a tool that..." | Passive, abstract | "Solves X by doing Y" |
| Screenshot-heavy | Breaks, doesn't copy-paste | ASCII + code blocks |
| No examples | Abstract claims don't sell | Every feature → example |
| Hiding limitations | Users discover painfully | Honest Limitations section |
| Single install method | Alienates users | curl + pkg manager + source |
| No troubleshooting | Support burden | Top 5 errors with fixes |
| Outdated badges | Looks abandoned | Remove or keep current |

## AGENTS.md Blurb Template

For CLI tools, include a condensed reference block:

```markdown
## tool — Brief Description

One-line description of what it does and key differentiator.

### Core Workflow

```bash
# 1. Initialize

# 2. Main operation
tool do-thing

# 3. View results
tool show

Key Flags

--flag1    # Description
--flag2    # Description

Storage

- Location 1: path/to/thing
- Location 2: path/to/other

Notes

- Important caveat 1
