What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. The core idea: write plain text with minimal formatting characters, and convert it to clean HTML whenever needed. A line starting with # becomes an <h1>; **bold** becomes <strong>.
The original spec had ambiguities, so multiple competing flavors emerged. Today, CommonMark is the widely adopted standard, and GitHub Flavored Markdown (GFM) extends it with tables, task lists, and syntax-highlighted code fences — most documentation tools support GFM.
Common Use Cases
