 The starter workflow template sets up the `PATH` to contain OpenJDK 8 for the x64 platform. If you want to use a different version of Java, or target a different architecture (`x64` or `x86`), you can use the `setup-java` action to choose a different Java runtime environment.
 
-For example, to use version 9.0.4 of the JDK for the x64 platform, you can use the `setup-java` action and configure the `java-version` and `architecture` parameters to `'9.0.4'` and `x64`.
+For example, to use version 11 of the JDK provided by Adoptium for the x64 platform, you can use the `setup-java` action and configure the `java-version`, `distribution` and `architecture` parameters to `'11'`, `'adopt'` and `x64`.
