-It uses `project=jdk&release_type=ga&sort_method=DATE&sort_order=DESC&vendor=adoptium` as filter parameters.
+It uses `image_type=<jre|jdk>&project=jdk&release_type=ga&sort_method=DATE&sort_order=DESC&vendor=adoptium` as filter parameters.
 
 It only uses the first 50 pages with 50 items per page.
+
+Use `java-jdk` or `java` as `lookupName` to get releases which come with the Java Development Kit.
+
+Use `java-jre`  as `lookupName` if you only want releases which come with the Java Runtime Environment.
+Currently only the LTS releases of Java come with the JRE.
