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.

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.
