Markdown Syntax Reference

Here is a complete quick-reference guide to Markdown syntax. All of these are supported in this editor:

What Is Markdown Used For?

README Files and Documentation

Markdown is the standard format for README files on GitHub, GitLab, and Bitbucket. When you visit a repository page, the README.md file is automatically rendered as formatted HTML. Technical documentation platforms like Read the Docs, MkDocs, and Docusaurus also use Markdown as their primary authoring format.

Content Management Systems

Many modern CMS platforms and static site generators use Markdown for content authoring. Ghost, Jekyll, Hugo, Gatsby, Astro, and Nuxt all support Markdown content files. Writers can focus on content without dealing with HTML tags, while the CMS handles the rendering.

Note-Taking Applications

Applications like Obsidian, Notion, Bear, Typora, and Logseq use Markdown as their native format. Markdown notes are portable plain text files that can be opened in any text editor and are not locked to a proprietary format.

Developer Communication

GitHub Issues, Pull Requests, and comments all support Markdown formatting. Slack, Discord, and many team communication tools also support Markdown or Markdown-like syntax for formatting messages with bold, italic, and code blocks.

Frequently Asked Questions

What is the difference between Markdown and Rich Text?

Rich text uses invisible formatting stored in a proprietary format (like .docx or .rtf) that requires specific software to render. Markdown stores formatting as readable plain text symbols that work in any text editor. Markdown files are smaller, more portable, and readable even without rendering.

How do I create a table in Markdown?

Use pipe characters to separate columns and hyphens for the header separator row. For example:

| Name | Age |
| --- | --- |
| Alice | 30 |
| Bob | 25 |

This produces a formatted table with a header row.

How do I add a line break in Markdown?

Add two or more spaces at the end of a line before pressing Enter to create a line break within the same paragraph. To start a new paragraph, leave a blank line between the two blocks of text.

Can I use HTML inside Markdown?

Yes. Most Markdown processors allow raw HTML to be used inside Markdown files and it will be passed through to the rendered output. This is useful for elements Markdown does not natively support, like colored text, custom div layouts, or embedded iframes.

How do I escape Markdown characters?

Use a backslash before any Markdown character to display it literally. For example \*text\* displays as *text* with asterisks visible rather than rendering as italic. This works for: \ ` * _ { } [ ] ( ) # + - . !
