+
+## Environment Variables
+
+The application uses environment variables for configuration. These are loaded from a `.env` file at runtime.
+
+### Setting Up Environment Variables
+
+1. Copy `.env.example` to `.env`:
+   ```bash
+   cp .env.example .env
+   ```
+
+2. Edit the `.env` file with your own values:
+   ```
+   # Public VAPID key for push notifications
+   PUBLIC_VAPID_KEY=your_public_vapid_key_here
+   
+   # Backend URL for push notifications
+   BACKEND_URL=https://your-push-server.example.com
+   ```
+
+3. For security, never commit your `.env` file to version control. It's already included in `.gitignore`.
+
+### Generating VAPID Keys
+
+For push notifications, you need to generate your own VAPID keys:
+
+```bash
+npx web-push generate-vapid-keys
+```
+
+Use the public key in your `.env` file and keep the private key secure for your backend server.
