First steps 2. Basic concepts 3. Quick tutorial ## Features ### Feature 1 How to use, examples, tips ### Feature 2 How to use, examples, tips ## Troubleshooting Common issues and solutions ## FAQ Frequently asked questions ``` ### Phase 4: Documentation Generation ```bash # Generate TypeDoc npx typedoc --out docs/api src # Generate OpenAPI spec npx swagger-jsdoc -d swaggerDef.js -o openapi.json # Generate markdown from code npx documentation build src/** -f md -o API.md # Build documentation site npm run docs:build ``` ### Phase 5: Quality Checks #### Documentation Checklist - [ ] README complete with all sections - [ ] API endpoints documented - [ ] Code has inline documentation - [ ] Examples provided - [ ] Installation instructions tested - [ ] Configuration documented - [ ] Troubleshooting section added - [ ] Changelog updated - [ ] Version numbers consistent #### Writing Guidelines 1. **Clarity** - Use simple, direct language 2. **Completeness** - Cover all features 3. **Accuracy** - Test all examples 4. **Consistency** - Use standard terminology 5. **Accessibility** - Consider all skill levels 6. **Searchability** - Use clear headings 7. **Maintainability** - Keep it DRY ## Quick Reference ### Essential Files ```bash # Create essential documentation touch README.md CONTRIBUTING.md CHANGELOG.md LICENSE mkdir -p docs/{api,guides,examples} # Documentation structure docs/ ├── api/ # API reference ├── guides/ # User guides ├── examples/ # Code examples └── images/ # Diagrams and screenshots ``` ### Markdown Tips - Use semantic headings (h1 for title, h2 for sections) - Include code examples with syntax highlighting - Add tables for structured data - Use lists for step-by-step instructions - Include diagrams when helpful - Link to related documentation ## Best Practices 1. **Start with README** - It's the entry point 2. **Document as you code** - Don't leave it for later 3. **Include examples** - Show, don't just tell 4. **Keep it updated** - Outdated docs are worse than no docs 5. **Test documentation** - Verify examples work 6. **Get feedback** - Ask users what's missing 7. **Version control** - Track documentation changes ## Tools & Resources - **Generators**: TypeDoc, JSDoc, Swagger - **Platforms**: Docusaurus, MkDocs, GitBook - **Linters**: markdownlint, alex - **Diagrams**: Mermaid, PlantUML - **API Testing**: Postman, Insomnia ## Success Criteria - ✅ All public APIs documented - ✅ README comprehensive - ✅ Examples run successfully - ✅ No broken links - ✅ Search functionality works - ✅ Mobile-responsive docs - ✅ Documentation builds without errors Remember: Good documentation is an investment that pays dividends in reduced support burden and increased adoption.
