+# Music Player Plugin for MioIsland
+
+A native plugin that brings real-time music playback information to your MioIsland Notch bar. See what's currently playing across any music app on your Mac without leaving your workflow.
+
+## Features
+
+- Displays the currently playing track, artist, and album from any macOS music app (Apple Music, Spotify, etc.)
+- Reads system NowPlaying metadata — no need to configure individual apps
+- Lightweight native `.bundle` plugin with minimal resource usage
+- Smooth animated UI that matches the MioIsland design language
+- Appears as a header icon button in the Notch bar
+
+## Screenshots
+
+*Coming soon*
+
+## Installation
+
+### From MioIsland Plugin Store
+
+1. Visit [miomio.chat](https://miomio.chat)
+2. Find "Music Player" and click Install
+3. MioIsland will automatically download and activate the plugin
+
+### Manual Installation
+
+```bash
+cp -r music-player.bundle ~/.config/codeisland/plugins/
+```
+
+Restart MioIsland to load the plugin.
+
+## Building from Source
+
+Requirements:
+- macOS 15.0+
+- Xcode Command Line Tools
+- Swift 5.9+
+
+```bash
+git clone https://github.com/xmqywx/mio-plugin-music.git
+cd mio-plugin-music
+bash build.sh
+```
+
+The build script outputs:
+- `build/music-player.bundle` — the plugin (copy to `~/.config/codeisland/plugins/`)
+- `build/music-player.zip` — compressed bundle for marketplace upload
+
+## Plugin Architecture
+
+| File | Purpose |
+|------|---------|
+| `MioPlugin.swift` | Plugin protocol definition |
+| `MusicPlugin.swift` | Main plugin entry point — activate, deactivate, makeView |
+| `MusicPlayerView.swift` | SwiftUI view displaying track info |
+| `MusicHeaderButton.swift` | Header icon button for the Notch bar |
+| `NowPlayingBridge.swift` | Bridges macOS NowPlaying system APIs |
+
+## How It Works
+
+The plugin uses macOS `MRMediaRemoteGetNowPlayingInfo` API to read the system-wide NowPlaying information. This works with any app that reports playback status to the system, including:
+
+- Apple Music
+- Spotify
+- YouTube (in browser)
+- VLC
+- Any app using MPNowPlayingInfoCenter
