What a .md file is

John Gruber created Markdown in 2004 so that formatted text would still be readable as raw text. It is the standard for README files, documentation, notes apps and static sites, and GitHub, Reddit and Discord all render a dialect of it. Any text editor opens one; dedicated editors such as Obsidian, Typora and VS Code show the formatted result alongside the source.

Converting it

A .md file is commonly converted to .html, .pdf, .docx, .txt or .epub. It is a plain text format, so any text editor can open and edit it directly.
