 [TIP]
 ====
-You can provide custom options for the `native-image` command using the `<quarkus.native.additional-build-args>` property.
+You can provide custom options for the `native-image` command using the `quarkus.native.additional-build-args` and `quarkus.native.additional-build-args-append` properties.
 Multiple options may be separated by a comma.
 
-Another possibility is to include the `quarkus.native.additional-build-args` configuration property in your `application.properties`.
+By convention `quarkus.native.additional-build-args-append` is meant to be defined at the command line (e.g. `-Dquarkus.native.additional-build-args-append=--verbose`), while `quarkus.native.additional-build-args` may be defined either at the command line or in your `application.properties`. Note that, any arguments included in `quarkus.native.additional-build-args-append` may override those included in `quarkus.native.additional-build-args`.
 
 You can find more information about how to configure the native image building process in the <<configuration-reference>> section below.
