 Native testing recommendation: you don't need to test in the mode all the time, especially if you are working with frameworks and libraries that support Native Image – usually everything just works. Develop and test your application on the JVM, and test in Native once in a while, as a part of your CI/CD process, or if you are introducing a new dependency, or changing things that are sensitive for Native Image (reflection etc). 
 
 # Using libraries
 
-# Configuring reflection
+When using libraries in native mode, some things such as reflection, resources, proxies might have to be made "visible" to Native Image at build time via configuration. Now the word "configuration" doesn't mean that this is something that you need to do manually as a user – let's look at all the many ways how this can just work.
+
+* Ideally, a library would include the necessary config files. Example: [H2](https://github.com/h2database/h2database/blob/master/h2/src/main/META-INF/native-image/reflect-config.json), [OCI Java SDK](https://github.com/oracle/oci-java-sdk/blob/master/bmc-adm/src/main/resources/META-INF/native-image/com.oracle.oci.sdk/oci-java-sdk-adm/reflect-config.json). In this case no further action needed from a user – things just work.
+* In cases when a library doesn't (yet) support GraalVM, the next best option is having configuration for it in the [GraalVM Reachability Metadata Repository](https://github.com/oracle/graalvm-reachability-metadata). It's a centralized repository where both maintainers and users can contribute and then reuse configuration for Native Image. It's integrated into [Native Build Tools](https://github.com/graalvm/native-build-tools) and now enabled by default, so as a user, again things just work.<br>
+For both of those options, a quick way to asses whether your dependencies work with Native Image is the ["Ready for Native Image"](https://www.graalvm.org/native-image/libraries-and-frameworks/) page. Note that this is a list of libraries that are *known* to be continuously testing with Native Image, and there are more compatible libraries out there; but this is a good first step for assessment.
