What is Markdown?
A Markdown file (typically ending in `.md`) is a plain text file that uses lightweight formatting symbols to add structure and style to text. Created in 2004 by John Gruber and Aaron Swartz, the goal was simple: let writers format text—headers, bold, lists, links—using only keyboard characters, without needing to reach for a mouse or open a toolbar. The result is a file that looks perfectly readable in its raw form and renders beautifully when processed by any Markdown-aware application.
For example, typing `bold` renders as bold, `# Title` produces a large heading, and a line starting with `- ` becomes a bullet point. The syntax is designed to feel natural even before it is rendered.
When to Use Markdown
Markdown has become the default language of software developers and modern writers. You should use it for:
- Software Documentation: Nearly every project on GitHub uses a Markdown `README.md` file.
- Fast Note Taking: Apps like Obsidian or Notion rely heavily on Markdown so you never have to move your hands off the keyboard.
- Web Content: Many blogging platforms let you write raw Markdown because it easily translates into clean web code (HTML).
When NOT to Use Markdown
Markdown isn't built for intricate, print-ready document design. If you need complex tables, precise image placement, or multiple text columns, you will find Markdown too restrictive.
How to Share Markdown with Others
The downside to Markdown is that non-technical people don't usually know how to read or open an `.md` file. Sending it directly to a client is typically a bad idea.
