+=== Wiring (java.util.logging)
+
+This section explains how to use JBoss Log Manager as the log manager
+for `java.util.logging` and how to configure it to use the log
+formatter provided by this library.
+
+Add a dependency on JBoss Log Manager and the `-core` module to your
+project.
+
+If you are using Maven:
+
+[source,xml]

+  </dependency>
+
+  <dependency>
+    <groupId>org.jboss.logmanager</groupId>
+    <artifactId>jboss-logmanager</artifactId>
+    <version>3.0.2.Final</version>
+  </dependency>

+</dependencies>
+----
+
+If you are using Gradle:
+
+[source,groovy]
+----

+  implementation("org.jboss.logmanager:jboss-logmanager:3.0.2.Final")
+}
+----
+
+Create a text file called `org.jboss.logmanager.ConfiguratorFactory`
+in your `resources/META-INF/services/` directory and put the fully
+qualified name of this library's `DefaultConfiguratorFactory` into it:
+
+[source]
+----
+eu.mulk.quarkus.googlecloud.jsonlogging.logmanager.DefaultConfiguratorFactory
+----
+
+Finally, set the `java.util.logging.manager` system property to
+`org.jboss.logmanager.LogManager` when running your application:
+
+[source,shell]
+----
+$ java -Djava.util.logging.manager=org.jboss.logmanager.LogManager ...
+----
+
+
 === Wiring (Spring Boot)
 
 If you are using Spring Boot, the easiest way to integrate the log
 formatter is by relying on `spring-boot-starter-logging` (which is
 pulled in by `spring-boot-starter`), excluding Logback, and pulling in
-JBoss Log Manager as the back end for SLF4J:
