Best Practices

1. Organize Content Logically

docs/
├── getting-started/
│   ├── installation.md
│   └── quick-start.md
├── guides/
│   ├── beginner/
│   ├── intermediate/
│   └── advanced/
└── reference/
    ├── api/
    └── cli/

2. Use Frontmatter

---
id: my-doc
title: My Document
sidebar_label: Short Label
sidebar_position: 1
description: Document description for SEO
keywords: [docusaurus, documentation, seo]
---

3. Leverage MDX

import MyComponent from '@site/src/components/MyComponent';

<MyComponent prop="value" />

4. Optimize Images

![Alt text](./img/photo.jpg)

<!-- Or with sizing -->
<img src={require('./img/photo.jpg').default} width="600" />

5. Add Edit Links

docs: {
  editUrl: 'https://github.com/org/repo/edit/main/',
},

Troubleshooting

Build Errors

# Clear cache
npm run clear
npm run build

Broken Links

# Check for broken links during build
npm run build -- --debug
