What is a .MARKDOWN file?
The plain-text way to write formatted documents.
A .MARKDOWN file is a developer document created by John Gruber. This text-based format contains documentation and is typically opened using text editors such as Microsoft Windows Notepad, Notepad++, gVim, and TextEdit. It can also be accessed through programs like Markdown and Middleman.

Frequently asked questions
Is my .MARKDOWN file uploaded?
No. Markdown is rendered for you.
Why don't my images show?
Images stored next to the .md file (like images/screenshot.png) aren't part of the file you opened, so we show a placeholder with the path. Images with a full web address (https://…) load normally.
Is it safe to open Markdown from strangers?
Yes. Markdown can contain raw HTML, so every rendered page is cleaned with DOMPurify: scripts, event handlers and dangerous links are removed before anything is shown.
Can I edit the Markdown?
Yes. In Split or Source view the left pane is editable and the preview updates as you type. Download the edited .md when you're done.
How do I make a PDF?
Click Print / PDF and choose Save as PDF in the print dialog. Only the rendered document is printed, without the page around it.
