+# Graal Native Image configuration
+
+This is a mish-mash of manual and automatic code generation.
+
+To _update_ the configurations, use:
+
+```declarative
+-agentlib:native-image-agent=config-merge-dir=cli/src/main/resources/META-INF/native-image
+```
+
+Please delete empty files and reformat the JSON!
+
+When running the JAR from the command line. This particular pathing, suggests that it be run from the root of the project.
+
+Note: With `asu` every subcommand should be executed to capture all the pieces!
+
+For example:
+
+```shell
+$ java -agentlib:native-image-agent=config-merge-dir=tools/asu/src/main/resources/META-INF/native-image \
+       -jar tools/asu/build/libs/applesingle-tools-asu-1.4.0-DEV.jar \
