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.

from phoenix.otel import register

register(auto_instrument=True)

For more details, you can check the docs and explore further options.
