+# Control your AIRMX Pro right from your Apple Home
+
+The package is a Homebridge plugin for AIRMX Pro, which allows you to
+control the AIRMX Pro on Apple Home across your devices, even with Siri.
+
+## Installation
+
+The plugin supports Node 18+ with Homebridge 1.8+ or 2.0. You can install
+the plugin via NPM:
+
+```bash
+npm i -g homebridge-airmx
+```
+
+## Usage
+
+This plugin supports Homebridge UI configuration; you can tweak the settings
+from Homebridge UI or edit the `config.json` file manually. Here's a simple
+example:
+
+```json
+{
+  "platforms": {
+    {
+      "name": "AIRMX",
+      "platform": "AIRMX",
+      "mqtt": "mqtt://192.168.10.10",
+      "devices": [
+        {
+          "id": 1,
+          "key": "<YOUR-DEVICE-KEY>"
+        }
+      ]
+    }
+  }
+}
+```
+
+My local anonymous MQTT server is deployed on my home network, and remember
+to update your endpoint. The devices field accepts a list where each item
+includes a device ID and the corresponding device key.
+
+Here's the technical specification for the configuration.
+
+<dl>
+  <dt>platform: string</dt>
+  <dd>The platform name must be set to "AIRMX".</dd>
+
+  <dt>mqtt: string</dt>
+  <dd>The broker URL for an MQTT server.</dd>
+
+  <dt>devices: device[]</dt>
+  <dd>A list of AIRMX Pro definitions.</dd>
+
+  <dt>device: object</dt>
+  <dd>An AIRMX Pro definition.</dd>
+
+  <dt>device.id: number</dt>
+  <dd>The device identifier.</dd>
+
+  <dt>device.key: string</dt>
+  <dd>The key is used to sign or validate the command messages in the MQTT server.</dd>
+</dl>
+
+## License
+
+The package is released under [the MIT license](LICENSE).
