-## Environment Variables
-
-The SDK supports configuration through environment variables:
-
-### Application Configuration
-
-| Variable            | Description                              | Default | Example                             |
-|---------------------|------------------------------------------|---------|-------------------------------------|
-| `LOGLEVEL`          | Sets the log level for the application   | `INFO`  | `DEBUG`, `INFO`, `WARNING`, `ERROR` |
-| `AGENT_A2A_RPC_URL` | RPC URL inserted into the A2A agent card | `None`  | `https://my-agent.example.com/a2a`  |
-
-### OpenTelemetry Configuration
-
-The SDK automatically configures OpenTelemetry observability. You can customize the OTLP exporters using standard OpenTelemetry environment variables:
-https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/
-
 ## Creating a release
 
 Create and push a GIT tag like `v0.1.0` and GitHub workflows will build and publish the package to PyPI.

 ## Features
 
 - Configures OTEL (Tracing, Metrics, Logging)
-- Converts an ADK agent into an instrumented starlette app with health endpoint
+- Converts an ADK agent into an instrumented starlette app
+- Configures A2A protocol for inter-agent communication
+- Offers parsing methods for sub agents and tools
