Complete Guide to Markdown Syntax, GFM & HTML Publishing
Markdown is a lightweight plain-text markup language created in 2004 by John Gruber and Aaron Swartz. Designed to be human-readable and easily converted to semantically valid XHTML and HTML5, Markdown is the universal standard for developer documentation (README.md), technical blogs, static site generators (Hugo, Jekyll, Astro), and collaborative platforms like GitHub, Reddit, and Discord.

Frequently Asked Questions (FAQs)
What is the difference between standard Markdown and CommonMark / GFM?
The original 2004 Markdown specification contained ambiguities in edge cases. CommonMark standardized the formal grammar, while GitHub Flavored Markdown (GFM) extended CommonMark with tables, task lists, auto-linking URLs, and strikethrough styling.
Can I embed raw HTML inside Markdown documents?
Yes. Markdown is a superset of HTML. Any valid HTML tag (such as <div>, <iframe>, <kbd>, or <img>) placed inside Markdown will pass through and render directly in the HTML output.
Is my documentation draft saved or sent to any server?
No. All live rendering, word counts, and HTML conversions happen 100% locally in your browser memory. No text or files are uploaded to external servers.
