-#### Disable the OpenTelemetry Starter
+#### General configuration
+
+The OpenTelemetry Starter supports all the
+[SDK Autoconfiguration](/docs/languages/java/automatic/configuration/#sdk-autoconfiguration)
+(since 2.2.0). You can set properties in the `application.properties` or the
+`application.yaml` file, or use environment variables.
+
+`application.properties` example:
+
+```properties
+otel.propagators=tracecontext,b3
+otel.resource.attributes=environment=dev,xyz=foo
+```
+
+`application.yaml` example:
+
+```yaml
+otel:
+  propagators:
+    - tracecontext
+    - b3
+  resource:
+    attributes:
+      environment: dev
+      xyz: foo
+```
+
+Environment variables example:
+
+```shell
+export OTEL_PROPAGATORS="tracecontext,b3"
+export OTEL_RESOURCE_ATTRIBUTES="environment=dev,xyz=foo"
+```
+
+Disable the OpenTelemetry Starter:
 
 {{% config_option name="otel.sdk.disabled" %}}
 
 Set the value to `true` to disable the starter, e.g. for testing purposes.

-- Logging
+##### Exclude actuator endpoints from tracing
 
-All available properties are listed in the
-[Configuration](/docs/languages/java/automatic/configuration/) page.
+As an example, you can customize the sampler to exclude health check endpoints
+from tracing:
 
-The only difference is that the OpenTelemetry Spring Boot starter uses
-`http/protobuf` as the default protocol for the OTLP exporter (as of 2.0.0+).
