  Phoenix has made it even simpler to get started with tracing by introducing one-line auto-instrumentation. By using `register(auto_instrument=True)`, you can enable automatic instrumentation in your application, which will set up instrumentors based on your installed packages.

  ```python theme={null}
  from phoenix.otel import register

  register(auto_instrument=True)
  ```

  For more details, you can check the docs and explore further [tracing](/docs/phoenix/tracing/how-to-tracing/setup-tracing) options.
