Markdown Preview Guide: Write Better Documentation
What Is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It is designed to be human-readable in plain text while converting cleanly to HTML. Markdown powers README files, documentation, forum posts, static site generators, and countless developer tools β making it the de facto standard for developer writing.
Why Use a Preview Tool?
Writing Markdown in a plain text editor means you cannot see what the rendered output looks like until you push to GitHub or build your site. A live preview tool shows you the rendered HTML side-by-side as you type, catching formatting errors instantly and letting you iterate on your content without the edit-commit-push-wait cycle.

Markdown Flavors
Different platforms support different Markdown extensions. GitHub Flavored Markdown (GFM) adds tables, task lists, and auto-linking. CommonMark is a standardized spec that resolves ambiguities in the original Markdown. When writing for a specific platform, check which flavor it supports.
