 Spark runs on both Windows and UNIX-like systems (e.g. Linux, Mac OS), and it should run on any platform that runs a supported version of Java. This should include JVMs on x86_64 and ARM64. It's easy to run locally on one machine --- all you need is to have `java` installed on your system `PATH`, or the `JAVA_HOME` environment variable pointing to a Java installation.
 
 Spark runs on Java 8/11/17, Scala 2.12/2.13, Python 3.7+ and R 3.5+.
+Java 11/17 is the recommended version to run Spark on.
 Python 3.7 support is deprecated as of Spark 3.4.0.
 Java 8 prior to version 8u201 support is deprecated as of Spark 3.2.0.
 When using the Scala API, it is necessary for applications to use the same version of Scala that Spark was compiled for.
