+
+[Vanilla Markdown](https://vanillamarkdown.com/) is a native macOS application for reading Markdown files without opening a full editor. It is designed as a read-only viewer: no cursor, no formatting toolbar, and no accidental edits.
+
+The app can open a single Markdown file, a folder, or a documentation tree. It renders common README features such as tables, task lists, code blocks, links, images, and embedded HTML. It also includes navigation features for larger documentation sets, including a table of contents, full-text search, viewing history, and a links panel for URLs and file paths.
+
+The free version supports viewing one file at a time. The paid version unlocks folder and multi-file navigation, recents, pinning, and other documentation-browsing features.
