-Calls to these libraries are instrumented with library-specific code adding tracing to them, including support for
-distributed traces.
+### Library Side

+Most integrations are added by orchestrion at the call site, making it possible to use the [`//orchestrion:ignore`
+directive][orchestrion-ignore] to locally opt out of instrumentation for a specific instance of a component.
+
+[orchestrion-ignore]: https://datadoghq.dev/orchestrion/docs/custom-trace/#prevent-instrumentation-of-a-section-of-code
+
+Some integrations are however injected directly into the library (library-side instrumentation, also called callee-side
+instrumentation), and are hence always active and cannot be locally opted out. If you have a use-case where you need to
+locally opt out of a library-side instrumentation, please let us know about it by filing a [GitHub issue][new-gh-issue].
