Why Markdown Won
Markdown is the plain-text formatting language that quietly became ubiquitous while nobody was watching. It started as a better way to write HTML by hand in 2004; today it is the format for README files on GitHub and GitLab, issue and pull-request comments on every major code-hosting platform, most developer blogs, documentation sites (MkDocs, Docusaurus, VitePress, Jekyll, Hugo), Discord and Slack messages, Notion and Obsidian notes, and countless internal wikis. The appeal is that it is readable as plain text and renders cleanly when a processor converts it to HTML — you can write it in any editor, commit it to any version control system, and still get formatted output downstream.
What This Preview Supports
This tool renders the core CommonMark specification: headers (# through ######), bold (**text**) and italic (*text*), inline code (`text`) and fenced code blocks, links ([text](url)) and images, ordered and unordered lists (including nested), blockquotes, and horizontal rules. Paste on the left and see the rendered HTML on the right, live. It is a quick way to proofread a README, draft an issue comment, or verify that a complex table will render the way you expect before committing it to a repository.
Markdown in Documentation Pipelines
For teams that run real documentation workflows — generating API docs from source, publishing changelogs automatically, embedding product screenshots, diff-rendering proposed changes — markdown is the source of truth and the build pipeline is where the work lives. I build documentation sites, developer portals, and content publishing workflows that start with markdown and end with accessible, indexed, versioned HTML.
