What Is Markdown Guide?

Updated

Markdown Guide (markdownguide.org) is a free and open-source reference site that teaches you how to write and format documents with Markdown. It suits anyone who needs to produce formatted text for the web, README files, notes, or documentation and wants a single place to look up syntax — from complete beginners following the Getting Started path to experienced users checking extended syntax for tables, fenced code blocks, and automatic links.

What the site actually is

The site describes itself as "a free and open-source reference guide that explains how to use Markdown, the simple and easy-to-use markup language you can use to format virtually any document." Two things follow from that description:

  • It is a reference and teaching resource, not a Markdown editor, converter, or hosting service. You read it to learn syntax; you write your Markdown somewhere else.
  • It is open-source and openly licensed. The footer credits the project as "A Matt Cone project" and marks the content CC BY-SA 4.0, so the material can be reused under that license.

It is also independent. The site is a community project, not the body that defines the Markdown standard, so treat it as an authoritative explainer rather than the formal specification.

What you can do on the site

The homepage lays out three learning paths, each aimed at a different starting point:

Path Who it's for What it covers
Getting Started Beginners, "even novices" Following along to begin using Markdown right away
Basic Syntax New and experienced users Answers to everyday formatting questions
Extended Syntax Users ready to go further Tables, fenced code blocks, automatic links, and more

There is also a Cheat Sheet for quick lookups, plus sections labeled Hacks, Tools, and a Book. The site notes you can "publish your Markdown as a web page in one click with JotBird," which is a third-party promotion rather than a core feature of the guide.

How to use it

  1. Start with Getting Started if Markdown is new to you. It is written to be followed along step by step, so you practice the syntax rather than just reading it.
  2. Keep Basic Syntax open while you write. When a heading, list, link, or emphasis does not render the way you expect, this page is the fastest check.
  3. Move to Extended Syntax when you need tables, fenced code blocks, or automatic links — features that go beyond the core syntax and are not supported identically everywhere.
  4. Use the Cheat Sheet once you know the basics and only need to confirm a symbol.

The expected result at each stage is the same: you can write plain text that a Markdown-aware tool will render as formatted output.

Common sticking points

  • Markdown is not one single standard. Because extended features vary between tools, a table or fenced code block that works in one editor may not work in another. Check the extended syntax page and then confirm against your own tool.
  • The guide is not your editor. If you are looking for something to write in or convert files with, the Tools section is the relevant part of the site, not the syntax pages.
  • Licensing matters if you reuse content. The CC BY-SA 4.0 notice means you can share and adapt the material, but attribution and share-alike terms apply.

When it is the right resource

Choose Markdown Guide if you want a free, structured, beginner-friendly path into Markdown plus a reliable syntax reference you can return to. Look elsewhere if you need the formal specification, a specific tool's documentation, or an editor and converter rather than a guide.
