Markdown is a lightweight markup language that uses plain text symbols to add formatting. For example, **text** renders as bold, # Heading creates a heading, and [link](url) creates a hyperlink. It is widely used in README files, documentation, and content management systems.

Wrap text with **double asterisks** or __double underscores__ for bold. Use *single asterisks* or _single underscores_ for italic. Combine for ***bold italic***. You can also select text in the editor and click the toolbar buttons.

Use pipes (|) to separate columns and hyphens (---) for the header separator row. Example: | Name | Score | |------|-------| | Alice | 95 | Click the Table button in the toolbar to insert a template.

Wrap your code with triple backticks (```). Add a language identifier after the opening backticks for syntax highlighting: ```js for JavaScript, ```python for Python, etc. The closing backticks go on their own line.

It downloads your current Markdown source as a .md file named "document.md". The file contains the raw Markdown text exactly as you typed it — useful for saving your work or using it in a project.

The editor is stateless — content is only kept in your browser's memory while the page is open. Refreshing the page resets it to the sample content. Use the "Copy MD" or "Download .md" button to save your work before leaving the page.
