+==== Customise Propagator
+
+To customise the propagation header you can implement the `TextMapPropagatorCustomizer` interface. This can be used, as an example, to restrict propagation of OpenTelemetry trace headers and prevent potentially sensitive data to be sent to third party systems.
+
+```java
+/**
+ * /**
+ * Meant to be implemented by a CDI bean that provides arbitrary customization for the TextMapPropagator
+ * that are to be registered with OpenTelemetry

 == Exporters
 
-Quarkus OpenTelemetry defaults to the standard OTLP exporter defined in OpenTelemetry.
+=== Default
+
+The Quarkus OpenTelemetry extension uses its own exporter built on top of Vert.x for optimal performance and maintainability.
+
+The exporter is automatically wired with CDI, that's why the `quarkus.otel.traces.exporter` property defaults to `cdi`.
 
+The `quarkus.otel.exporter.otlp.traces.protocol` default to `grpc` and `http/protobuf` can also be used.
+
+=== On Quarkiverse
 Additional exporters will be available in the Quarkiverse https://github.com/quarkiverse/quarkus-opentelemetry-exporter/blob/main/README.md[quarkus-opentelemetry-exporter] project.
 
+=== OpenTelemetry exporter
+The default OpenTelemetry exporter can be used, but it's not recommended because of the additional dependency on the OkHttp library.
+
+It can be activated by setting `quarkus.otel.traces.exporter=otlp` and include the following dependencies in your project:
