 The instructions for writing the WearOS apps with react-native are available at [alternative-installation.md](docs/alternative-installation.md). React Native does not officially support WearOS, some essential components like CircularScrollView are not available in React Native.

 ## FAQ on Troubleshooting Errors
 
 While some error messages are displayed on the metro server for the mobile or wearOS device (port 8082), other warnings are only available through logcat.

+# Huawei Setup
+
+To use Huawei wearables with this library you must configure Huawei Mobile Services (HMS) and pair the watch with your phone.
+
+## HMS Core configuration
+
+1. Create an app in the [Huawei Developer Console](https://developer.huawei.com/).  
+2. Download the `agconnect-services.json` file and place it in your Android project under `android/agconnect-services.json`.
+3. Ensure the following are added to your `android/build.gradle`:
+   - `maven { url 'https://developer.huawei.com/repo/' }`
+   - `classpath 'com.huawei.agconnect:agcp:1.9.1.301'`
+   - `implementation 'com.huawei.hms:wearengine:5.0.0.300'`
+4. Apply the `com.huawei.agconnect` plugin and sync your project.
+
+## Pairing the watch
+
+1. Install the Huawei Health app on your mobile device.
+2. Sign in with your Huawei ID and add your wearable device.
+3. Ensure the watch is connected via Bluetooth before testing message or file transfer APIs.
+
+These steps prepare the environment so `react-native-wear-engine` can communicate with the paired Huawei watch through this library's unified API.
