What if I don't have OpenTelemetry installed?

No worries! You can get started with no code changes at all!

This page will explain getting started with OpenTelemetry:

• Injecting auto instrumentation with no code changes.
• Auto instrumentation with limited code changes.
• Manual instrumentation with code changes.

You can also find more ways to instrument OpenTelemetry in their documentation.
