 This is a polyglot Helidon HTTP web service that demonstrates how multiple JavaScript `Context`s can be executed in parallel to handle asynchronous operations with [Helidon](https://helidon.io/), mixing JavaScript `Promise` and Java `CompletableFuture` objects.
 
-## Prerequisites
-* [GraalVM](http://graalvm.org)
-
 ## Preparation
 
 1. Download and install the latest GraalVM JDK using [SDKMAN!](https://sdkman.io/).
     ```bash
-    sdk install java 21.0.1-graal
+    sdk install java 21.0.5-graal
     ```
 
 2. Download or clone the repository and navigate into the `js-java-async-helidon` directory:
     ```bash
     git clone https://github.com/graalvm/graalvm-demos
     ```
     ```bash
-    cd graalvm-demos/js-java-async-helidon
+    cd graalvm-demos/archive/js-java-async-helidon
     ```
 
 3. Build the application using Maven:
     ```bash
     mvn clean package
     ```

 Open [http://localhost:8080/greet?request=42](http://localhost:8080/greet?request=42) in the browser to send a request.
 
 To demonstrate error handling, the application will not accept requests with `request` smaller than `42`.
 For example, the following requests will return an error message:
 ```bash
 curl http://localhost:8080/greet?request=41
+```

 curl http://localhost:8080/greet?request=foo

 This is a sample application that, for brevity, contains reasonably large snippets of code inside the strings.
 This is not the best approach for structuring polyglot apps, but the easiest to show in a compact way.
