Install on macOS 13+ (Apple Silicon) using Homebrew.
brew install --cask yurseria/tap/simple-noteUpdate with brew update followed by brew upgrade --cask yurseria/tap/simple-note. The app installs as Note.app.
The app is not Developer ID signed or notarized. If macOS blocks it, use System Settings → Privacy & Security → Open Anyway only if you trust the app. Homebrew does not bypass Gatekeeper.
Windows users can download .exe or .msi; Linux users can download .deb or .AppImage from GitHub Releases.
See the Homebrew Tap for existing-install guidance and release integration for maintainers.

npm run package:tauriBuild artifacts are output to each package's directory:
- Electron:
packages/electron/dist/ - Tauri:
packages/tauri/src-tauri/target/release/bundle/
When running npm run package:electron on Windows, a symbolic link creation error (ERROR: Cannot create symbolic link) related to winCodeSign may occur, causing the build to fail. This is due to Windows security policies. Resolve it using one of the following methods:
- Enable Developer Mode (Recommended): Go to Windows Settings > System (or Update & Security) > For Developers > turn on Developer Mode.
- Run as Administrator: Open your terminal (VS Code, PowerShell, CMD) with Administrator privileges before running the packaging command.
