Helper Scripts

Generate Table of Contents

Use the helper script to automatically generate TOC from headers:

python scripts/markdown_helper.py toc README.md

Generate Changelog from Git

Automatically create changelog entries from git history:

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

Validate Markdown Links

Check for broken links in documentation:

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

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

List Formatting

<!-- 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

*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.
