+
+   ```plaintext title=".env.fsp-observer"
+   # Required
+   RPC_BASE_URL="https://flare-api.flare.network"                # Flare RPC endpoint
+   IDENTITY_ADDRESS="0x0000000000000000000000000000000000000000" # your identity address
+
+   # Optional notification channels
+   NOTIFICATION_DISCORD_WEBHOOK="https://discord.com/api/webhooks/..."
+   NOTIFICATION_TELEGRAM_BOT_TOKEN="your-telegram-bot-token"
+   NOTIFICATION_TELEGRAM_CHAT_ID="your-telegram-chat-id"
+   NOTIFICATION_SLACK_WEBHOOK="https://hooks.slack.com/services/..."
+   NOTIFICATION_GENERIC_WEBHOOK="http://host:port/path"          # generic POST webhook
+   ```
+
+   :::warning
+
+   Make sure this env file is **not committed** to version control (add it to `.gitignore` if needed).
+

+2. Run the observer using Docker:
+
+   ```bash
+   docker run --env-file .env.fsp-observer ghcr.io/flare-foundation/fsp-observer:main
+   ```
+
+The container will watch your identity and send notifications to any configured channels when issues are detected.
