+# ThinkPad Logo LED
+
+A simple Noctalia bar widget to toggle the ThinkPad lid logo LED on and off.
+
+## Plugin
+
+| Property | Value |
+| --- | --- |
+| **ID** | `zeti1223/thinkpad-led` |
+| **Widget** | `led` |
+| **Version** | `1.1.0` |
+| **Author** | zeti1223 |
+| **License** | MIT |
+
+## Usage
+
+Add the `led` widget to your Noctalia bar layout. Clicking the widget toggles the ThinkPad logo LED state.
+
+* **Left Click**: Toggle LED (ON / OFF).
+
+## Requirements
+
+* `sh`
+
+## Notes
+
+* **Hardware & Permissions**: This plugin writes directly to `/sys/class/leds/tpacpi::lid_logo_dot/brightness`. Ensure your user account has write permissions to this path (for example, via a `udev` rule), otherwise command execution will fail.
