+An important part of the configuration is the _reachability metadata_, which covers dynamic features used at runtime and which can't
+be discovered statically at build time. Akka provides Native Image metadata for many of the modules, and can detect and register
+user messages when using Akka Serialization Jackson, so a client application may not need to define any additional reachability metadata.

+For more details on what support Akka provides see the @extref[Akka documentation on Native Image](akka:additional/native-image.html).
 
 ### GraalVM tracing agent
 
-GraalVM provides a [tracing agent][native-image-tracing] to automatically gather metadata and create configuration
-files. The tracing agent tracks usage of dynamic features during regular running of the application in a JVM, and
-outputs Native Image configuration based on the code paths that were exercised. The build tool plugins for Native Image
-provide ways to run locally with the tracing agent enabled. It can also be useful to deploy your application to a
-testing environment with the GraalVM tracing agent enabled, to capture usage in an actual deployment environment and
-exercising all the Akka Edge features that are being used.
+If an application uses special features or libraries not supported out of the box with Akka it is possible to automatically
