 ### Install Prerequisites
 
-#### JDK 11
+#### JDK 21
 
-OpenSearch builds using Java 11 at a minimum, using the Adoptium distribution. This means you must have a JDK 11 installed with the environment variable `JAVA_HOME` referencing the path to Java home for your JDK 11 installation, e.g. `JAVA_HOME=/usr/lib/jvm/jdk-11`. This is configured in [buildSrc/build.gradle](buildSrc/build.gradle) and [distribution/tools/java-version-checker/build.gradle](distribution/tools/java-version-checker/build.gradle).
