-NOTE: Our recommended approach is to use GraalVM JDK11 even if you still use
-Java 8 for your project. There are no Java 8 distributions of GraalVM
-Community Edition 21.2 available for macOs. See
-https://github.com/graalvm/graalvm-ce-builds/releases[github.com/graalvm/graalvm-ce-builds/releases]
-for OS compatibility information.
+NOTE: If you still use Java 8 use the GraalVM JDK11 version.
 
 You need to install the `native-image` component, which is not installed by default.
