Markdown Mastery

Write expressive, beautifully formatted markdown — from basic documents to complex technical content with diagrams, advanced formatting, and automated tooling.

Core Principles

1. Markdown Is Code — Treat It With Respect

Formatting consistency matters. Lint your markdown, format it automatically, keep line lengths reasonable, and use semantic elements correctly.

2. Every Element Has a Purpose

Don't use bold where a heading belongs. Don't use inline code where a code block is needed. Don't use manual numbering where list numbering works. Semantic markdown is readable markdown.

3. Diagrams Are Documentation

A Mermaid diagram is worth a thousand words of architectural explanation. Embed diagrams directly in documentation — they version alongside the code and never go out of sync.

4. Write for Plain Text First

Markdown's superpower is readability in its raw form. Even without a renderer, your document should be scannable and understandable.
