 ### IDE Builds (for development)
 
-* Configure ITJ Gradle to use JDK 17 (in settings, search for gradle)
+* Configure ITJ Gradle to use JDK 21 (in settings, search for gradle)
 * Add a build line in the build.gradle for your own build task to directly compile Iris into your plugins folder if you
   prefer.
 * Resync the project & run your newly created task (under the development folder in gradle tasks!)
