+### 📊 Telemetry
+Configure external telemetry settings to monitor and analyze your AI-powered development workflows with environment-specific customization capabilities.
+
+- **External Configuration Override**  
+  - Support for telemetry configuration overrides via a `.hai.config` file placed at the root of your workspace.
+  - Enables environment-specific customization that can be dynamically injected through CI/CD pipelines.
+
+- **Supported Override Parameters**  
+  ```
+  # Langfuse Configuration
+  langfuse.apiUrl=
+  langfuse.apiKey=
+  langfuse.publicKey=
+  
+  # PostHog Configuration
+  posthog.url=
+  posthog.apiKey=
+  ```
+
+**Important Notes:**  
+- The `.hai.config` file is not git-excluded by default. Ensure sensitive keys are not committed unintentionally to your repository.
