## Helper Scripts

### Generate Table of Contents

Use the helper script to automatically generate TOC from headers:

```bash
python scripts/markdown_helper.py toc README.md
```

### Generate Changelog from Git

Automatically create changelog entries from git history:

```bash
python scripts/markdown_helper.py changelog --since v1.0.0 --output CHANGELOG.md
```

### Validate Markdown Links

Check for broken links in documentation:

```bash
python scripts/markdown_helper.py validate docs/
```

## Templates

### Professional README Template

See `examples/README_template.md` for a complete, production-ready README template with all recommended sections.

### Changelog Template

See `examples/CHANGELOG_template.md` for a properly formatted changelog following Keep a Changelog format.

### Contributing Guidelines

See `examples/CONTRIBUTING.md` for contributor guidelines template including code of conduct, development setup, and PR process.

## Best Practices Summary

### Do's
- Use clear, descriptive headers
- Include code examples for every major feature
- Add badges for quick project status overview
- Keep line length under 100 characters for readability
- Use syntax highlighting for code blocks
- Include table of contents for documents >300 lines
- Add alt text for all images
- Link to related documentation

### Don'ts
- Don't use generic titles like "My Project"
- Don't include wall-of-text paragraphs (break into sections)
- Don't forget to update changelog with releases
- Don't use bare URLs (always use descriptive link text)
- Don't mix heading styles (use consistent hierarchy)
- Don't include screenshots without descriptions
- Don't hardcode version numbers everywhere (use variables/badges)

## Quick Reference

### Header Hierarchy
```markdown
# H1 - Project Title (only one per document)
## H2 - Major Sections
### H3 - Subsections
#### H4 - Minor Points
##### H5 - Rare, for deep nesting
```

### List Formatting
```markdown
<!-- Unordered -->
- Item 1
- Item 2
  - Nested item
  - Another nested item

<!-- Ordered -->
1. First step
2. Second step
3. Third step

<!-- Task list -->
- [x] Completed task
- [ ] Pending task
- [ ] Another pending task
```

### Emphasis
```markdown
*italic* or _italic_
**bold** or __bold__
***bold italic*** or ___bold italic___
~~strikethrough~~
`inline code`
```

## Conclusion

Professional Markdown documentation improves project accessibility, attracts contributors, and provides clear guidance for users. Use the templates in `examples/` as starting points, customize with the helper scripts in `scripts/`, and follow these best practices for polished, maintainable documentation.
