directions for use

01Only Markdown. Opens and saves plain .md / .markdown. No database, no other formats.

02Editor + rendered. A monospace source editor and the rendered page, side by side, live.

03Right in Finder. Renders in Quick Look and on thumbnails — just press space.

04Export. Save the rendered document to PDF or HTML.

05That's all. No settings, no accounts, no toolbar to learn. The UI is barely there.

It does one small thing: it lets you see what you wrote.
