 ### JDK Version
 
-This project uses Java 21 Language Level api, but builds with both Java 21 and Java 25, so creates two different artifacts. 
-Both have the same group id `io.nats`, and the same version but have different artifact names. 
+This project uses Java 8 Language Level api, but builds jars compiled with and targeted for Java 8, 17, 21 and 25.
+It creates different artifacts for each. All have the same group id `io.nats` and the same version but have different artifact names. 
 
-* The Java 21 artifact id is `jnats-json-jdk21`
-* The Java 25 artifact id is `jnats-json-jdk25`

 ### Dependency Management
 
 The NATS client is available in the Maven central repository, 
 and can be imported as a standard dependency in your `build.gradle` or `pom.xml` file,
-The examples shown use the jdk 21 version, to the jdk 25 version just change the artifact id. 
+The examples shown use the Jdk 8 version. To use other versions, change the artifact id.
