# TypeOpen
-TypeOpen is a TriHerm Labs open-source desktop Markdown editor for macOS focused on a clean live editing workflow: write Markdown while seeing a rendered document, switch to source when needed, navigate a folder/outline, and export to common document formats.
+**A lightweight, open-source Markdown editor for macOS.**
-[](https://github.com/TriHerm/TypeOpen/releases/latest)
+Write in a live, formatted Markdown editor, switch to the source whenever you need full control, and navigate your documents without leaving your writing flow. TypeOpen is an independent, Typora-style Markdown editor for Apple Silicon Macs, built with Swift/AppKit, WKWebView and a React/Lexical editing surface.
-The default macOS build uses a small Swift/AppKit shell with the system WKWebView rather than bundling Chromium. This keeps the application in the same lightweight architectural class as native WebKit editors while preserving TypeOpen's React/Lexical editor surface.

+[](LICENSE)
-This project is an independent clean-room implementation. It does not contain Typora source code, decompiled function bodies, icons, themes, license/update mechanisms, or proprietary assets. REA was used locally to inventory user-visible behavior from a legally supplied application bundle; the reference application and raw REA evidence are explicitly excluded from Git and release artifacts.

+ Document Outline |
+
+
+
+TypeOpen keeps your documents in Markdown: write with formatted headings, lists, tables, links, images and code; switch to raw source when needed; or jump between sections with a navigable outline. The current native macOS distribution uses Swift/AppKit with WKWebView on Apple Silicon, not bundled Chromium.
+
+The images above are frames from the TypeOpen product demo. TypeOpen is developed independently and is **not affiliated with Typora**. For supported features and known gaps, see the [feature and compatibility matrix](docs/PARITY_MATRIX.md).
+
+## Install with Homebrew
+
+Homebrew is the recommended installation path for TypeOpen on Apple Silicon Macs:
+
+```bash
+brew install --cask triherm/tap/typeopen
+```
+
+The Cask is maintained in the public [`TriHerm/homebrew-tap`](https://github.com/TriHerm/homebrew-tap) repository and tracks the matching immutable GitHub release artifact.
+
+TypeOpen is currently ad-hoc signed and not notarized. Homebrew keeps macOS quarantine enabled, so Gatekeeper may block the first launch. If you trust the release, open TypeOpen once and approve it through **System Settings → Privacy & Security → Open Anyway**.
+
+You can also download the current Apple Silicon DMG directly from [GitHub Releases](https://github.com/TriHerm/TypeOpen/releases/latest).
+
+## Requirements
+
+- macOS 13 or newer.
+- Apple Silicon (`arm64`) for the current public release.
+- Optional: Pandoc 2+ for advanced import/export formats.
+
+For development from source, use Node.js 22.12+, npm 11+, and Xcode Command Line Tools with `swiftc`.
