# painlessMesh Documentation - Docusaurus Migration

## Overview

This document outlines the migration from the current custom documentation approach to **Docusaurus 3** for better user experience and maintainability.

## Current Issues

### Broken Links Found
- `docs/tutorials/custom-packages.md` - Missing
- `docs/tutorials/sensor-networks.md` - Missing  
- `docs/advanced/performance.md` - Missing
- `docs/architecture/routing.md` - Missing

### Problems with Current Approach
1. **Raw Markdown** - No processing, links break in GitHub Pages
2. **Manual HTML generation** - Basic and unmaintainable
3. **Doxygen isolation** - Separate from user documentation
4. **No link validation** - Broken links undetected
5. **No search functionality** - Poor discoverability
6. **Poor mobile experience** - Not responsive

## Proposed Solution: Docusaurus 3

### Why Docusaurus?
- ✅ **Modern React-based** - Fast, responsive, beautiful
- ✅ **Built-in search** - Algolia integration
- ✅ **API docs integration** - Seamless with Doxygen
- ✅ **Link validation** - Automatic broken link detection
- ✅ **Versioning support** - Multiple library versions
- ✅ **GitHub Pages deployment** - Automated CI/CD
- ✅ **SEO optimized** - Better search engine ranking

### Implementation Plan

#### Phase 1: Setup Docusaurus
```bash
# Initialize Docusaurus
npx create-docusaurus@latest website classic

# Configure for painlessMesh
cd website
npm install --save @docusaurus/plugin-client-redirects
npm install --save @docusaurus/theme-mermaid
```

#### Phase 2: Content Migration
1. **Migrate existing docs** to `docs/` folder
2. **Create missing pages** identified in review
3. **Fix all broken links** 
4. **Integrate Doxygen** output
5. **Add interactive examples**

#### Phase 3: Enhanced Features
1. **Search integration** with Algolia
2. **API documentation** with auto-generated content
3. **Interactive code examples** 
4. **Version management** for releases
5. **Analytics integration**
