 ## Setup
 
-This demo was developed against JDK 9+181 (first official version of [Java 9](http://www.oracle.com/technetwork/java/javase/downloads/jdk9-downloads-3848520.html)).
-For it to work, the Java 9 variants of `javac`, `jar`, and `java` must be available on the command line via `javac9`, `jar9`, and `java9`, e.g. by symlinking ([Linux, MacOS](https://stackoverflow.com/q/1951742/2525313), [Windows](https://www.howtogeek.com/howto/16226/complete-guide-to-symbolic-links-symlinks-on-windows-or-linux/)) them.
+This demo was developed against JDK 9.0.4.
+The command line scripts for shell and batch use the default commands `javac`, `jar`, and `java`.
+If these commands don't refer to the Java 9 version on your system, you can enter the appropriate paths at the top of each script.
 
 This is a multi-module Maven project, which your IDE should be able to import. If you're using Maven directly, make sure you have 3.5.0 or higher.

 ### Scripts
 
-The root directory contains a number of Linux shell scripts:
-
-* `compile.sh`: compiles the modules one by one
-* `multi-compile.sh`: compiles all modules at once
-* `dry-run.sh`: launches the application with `--dry-run`, which aborts before calling the main method
-* `run.sh`: launches the application
