 NOTE: There are other build items specialized in transformation: <<additional_interceptor_bindings>> and <<injection_point_transformation>>.
 
+=== How to Enable Trace Logging for Annotation Transformers
+
+You can set the `TRACE` level for the category `io.quarkus.arc.processor` and try to analyze the log output afterwards.
+
+.`application.properties` Example
+[source,properties]
+----
+quarkus.log.category."io.quarkus.arc.processor".min-level=TRACE <1>
+quarkus.log.category."io.quarkus.arc.processor".level=TRACE
+----
+<1> You also need to adjust the minimum log level for the relevant category.
