+# Zellij Socktop Plugin
+
+A Zellij plugin that displays real-time system metrics from a socktop agent.
+
+## Quick Start
+
+1. **Build the plugin:**
+   ```bash
+   cargo build --target wasm32-wasi --release
+   ```
+
+2. **Install in Zellij:**
+   ```bash
+   # Copy the WASM file to Zellij plugins directory
+   mkdir -p ~/.config/zellij/plugins
+   cp target/wasm32-wasi/release/zellij_socktop_plugin.wasm ~/.config/zellij/plugins/socktop.wasm
+   cp plugin.yaml ~/.config/zellij/plugins/
+   ```
+
+3. **Use in Zellij layout:**
+   ```yaml
+   # ~/.config/zellij/layouts/socktop.yaml
+   template:
+     direction: Horizontal
+     parts:
+       - direction: Vertical
+         borderless: true
+         split_size:
+           Fixed: 1
+         run:
+           plugin:
+             location: "file:~/.config/zellij/plugins/socktop.wasm"
+             configuration:
+               server_url: "ws://localhost:3000/ws"
+       - direction: Vertical
+   ```
+
+4. **Launch Zellij with the layout:**
+   ```bash
+   zellij --layout socktop
+   ```
+
+## Plugin Features
+
+- **Real-time Metrics**: Displays CPU and memory usage
+- **Auto-refresh**: Updates every 2 seconds
+- **Reconnection**: Press 'r' to reconnect to socktop agent
+- **Configurable**: Set custom server URL in plugin config
+- **Error Handling**: Shows connection status and errors
+
+## Configuration Options
+
+- `server_url`: WebSocket URL for socktop agent (default: `ws://localhost:3000/ws`)
+
+## Controls
+
+- **`r`** - Reconnect to socktop agent
+- Plugin updates automatically every 2 seconds
+
+## Development Notes
+
+This is a scaffold implementation. To make it fully functional:
+
+1. **Async Operations**: Zellij plugins have limitations with async operations. You may need to:
+   - Use a different async runtime or approach
+   - Handle WebSocket connections in a background thread
+   - Use message passing between threads
+
+2. **Error Handling**: Add more robust error handling for:
+   - Network connectivity issues
+   - Invalid server URLs
+   - Agent unavailability
+
+3. **UI Improvements**: 
+   - Add more detailed metrics display
+   - Implement scrolling for large datasets
+   - Add color coding for status indicators
+
+4. **Performance**: 
+   - Implement caching to reduce agent requests
+   - Add configurable update intervals
+   - Optimize WASM binary size
+
+## Dependencies
+
+- `zellij-tile`: Zellij plugin framework
+- `socktop_connector`: WebSocket connector with WASM support
+- `serde`: JSON serialization
+- `chrono`: Time handling (WASM-compatible)
+
+## Building
+
+```bash
+# Add WASM target
+rustup target add wasm32-wasi
+
+# Build for WASM
+cargo build --target wasm32-wasi --release
+
+# The plugin will be at: target/wasm32-wasi/release/zellij_socktop_plugin.wasm
+```
