+## App Variants
+
+This app supports building different variants using environment configuration files. This is useful for maintaining multiple versions of the app (e.g., production, staging, or different client configurations).
+
+### Available Variants
+
+- **Default**: Uses `.env.default` configuration
+- **Variant**: Uses `.env.variant` configuration
+
+### Setting Up Variants
+
+1. Create your variant environment files:
+
+   ```bash
+   cp .env .env.default
+   cp .env .env.variant
+   ```
+
+2. Update each environment file with the appropriate configuration values for that variant.
+
+### Building Variants
+
+To build a specific variant for Android:
+
+**Default variant:**
+```bash
+npm run android:build:default
+```
+
+**Variant build:**
+```bash
+npm run android:build:variant
+```
+
+> **Note**: Each build command will temporarily copy the corresponding `.env.*` file to `.env` before building.
+
 ## Production Releases
 
 For production Android releases, you'll need the actual `secrets.properties` file and keystore. Get these from the mobile team or 1Password.
