Markdown stores readable text with simple characters that indicate structure and formatting. It is widely used for documentation, notes, websites, software projects, messages, and content that may be rendered into HTML or other formats.
Plain-text files are portable, searchable, versionable, and easy for tools or agents to edit. Different Markdown variants support different features, so systems should agree on syntax and preserve links, metadata, code blocks, and other literal content carefully.

Markdown is a simple way to add structure to plain text using familiar punctuation. A line beginning with a hash can be a heading, square brackets can label a link and backticks can mark code.
For example, a project can keep its setup guide in a readable README.md file and convert it into a formatted webpage. AI tools can also retrieve that clean text without loading the site's menus, styles and scripts.
Why use Markdown for notes and knowledge bases?
Markdown files are readable, portable, searchable, versionable, linkable, and supported by many editors and publishing tools.
Is all Markdown syntax identical?
