Frequently asked questions

Everything you need to know.

What is markdown syntax?

Markdown is a lightweight markup language that uses plain-text characters like asterisks, hashes, and brackets to format text. It was created by John Gruber in 2004 and is now the standard for README files, documentation, and AI-generated content.

What is markdown syntax?

How many markdown elements are there?

Standard markdown includes about 15 core elements (headings, bold, italic, links, images, lists, code, blockquotes, etc.). Extended syntax like GitHub Flavored Markdown adds tables, strikethrough, task lists, and more — totaling 50+ distinct elements.

What is the difference between markdown and HTML?

Markdown is a simpler, more readable syntax that converts to HTML. Where HTML uses tags like <strong>, markdown uses **asterisks**. Markdown is faster to write but less flexible than raw HTML.

Does every platform support the same markdown?

No. GitHub, Discord, Slack, Reddit, and Notion each support different subsets of markdown. Our reference pages show platform support for every element so you know exactly what works where.

What is the best way to learn markdown?

Start with the basics — headings, bold, italic, links, and lists. These five elements cover 90% of everyday markdown use. Then explore our reference for advanced elements like tables, code blocks, and footnotes.
