Overview

Markion is a native desktop Markdown editor built with Rust and GPUI, moving freely between source, visual editing, and live preview. These pages cover installation, editing modes, the workspace, rendering, themes, export, and keyboard shortcuts in full detail.

Quick start

Download the latest build from GitHub Releases:

Platform	Release packages	Target
Windows	NSIS `.exe` NSIS installer	x86_64
macOS	`.app` and `.dmg`	Apple Silicon (arm64), macOS 11+
Linux	`.deb` and AppImage	x86_64

About security prompts. Releases are not platform code-signed. Windows SmartScreen may require More info → Run anyway, and macOS Gatekeeper may require right-clicking the app and choosing Open. The macOS package supports Apple Silicon only; Intel Mac packages, a universal binary, and Apple notarization are not currently provided.

In-app updates

Help → Check for Updates… offers an actionable update prompt on every platform:

Tagged Windows x86_64 NSIS installations get a cryptographically verified (cargo-packager Minisign) one-click download-and-install that refuses to start while any document has unsaved changes.
macOS and Linux open the matching release file in the system browser so you can download and install it yourself. Linux prefers AppImage on Arch-like systems and DEB on Debian-family systems.
