Markdown Formatting Guide
Markdown is a lightweight markup language created by John Gruber that allows you to write formatted text using a plain text editor. It converts easily to HTML and is widely used for README files, documentation, forum posts, and static site generation.
Basic Syntax
- Headings — Use
#through######for heading levels.# Titleis the largest,######is the smallest. - Bold and italic — Wrap text with
**double asterisks**for bold,*single asterisks*for italic, and***triple***for bold italic. - Links — Format as
[link text](url)to create clickable hyperlinks. - Images — Use
to embed images in your document. - Code — Use backticks
`code`for inline code and triple backticks```for code blocks. - Blockquotes — Precede text with
>to create a quoted block, useful for citing sources. - Lists — Use
-or*for unordered lists and numbers for ordered lists.
Where Markdown is Used
- GitHub and GitLab — README.md files, issue descriptions, pull request descriptions, and wiki pages all use Markdown.
- Static site generators — Tools like Jekyll, Hugo, and Next.js use Markdown for content authoring.
- Note-taking apps — Obsidian, Notion, and Bear support Markdown for rich text notes.
- Documentation — Many documentation frameworks (MkDocs, Docusaurus, ReadTheDocs) use Markdown as their source format.
