-# GraalVM Java to JavaScript Polyglot Debugging
+# Debugging a Java with JavaScript Embedding Application
 
-This sample code helps to demonstrate simplicity of debugging and developing GraalVM Polyglot applications using __VS Code extensions__.
+This sample code helps to demonstrate simplicity of debugging and developing GraalVM polyglot applications using Visual Studio (VS) Code extensions.
 
 ## Prerequisites
 
-1. VS Code has to be installed.
+1. Install VS Code and launch it.
 2. Then go to VS Code Extensions activity panel and search for _GraalVM Extension Pack_, install it. The GraalVM Extension Pack will install all required extensions.
-3. [Install GraalVM in VS Code](https://www.graalvm.org/latest/tools/vscode/graalvm-extension/#graalvm-installation-wizard): Navigate to Gr activity panel in VS Code and install some of the latest GraalVM __Enterprise Edition__ versions available from the list.
+2. Open Visual Studio Code, navigate to Extensions activity panel in the left-hand side Activity Bar. Search for “GraalVM” in the search field. Find  [GraalVM Tools for Java](https://marketplace.visualstudio.com/items?itemName=oracle-labs-graalvm.graalvm), press Install. Reload will be required.
+3. [Install GraalVM in VS Code](https://www.graalvm.org/latest/tools/vscode/graalvm-extension/#graalvm-installation-wizard): Navigate to Gr activity panel in VS Code and install the latest Oracle GraalVM version available from the list.
 4. Confirm to set this as _Active GraalVM_ for VS Code.
-5. Install the `js` component.
 
-## Debugging the project
-
-Working with Polyglot project in VSCode is simple just open this sample.
+## Build and Run the Application
+
+1. Open VS Code Terminal. 
+2. Clone the repository and navigate into the `polyglot-debug` directory:
+    ```bash
+    git clone https://github.com/graalvm/graalvm-demos
+    ```
+    ```bash
+    cd graalvm-demos/polyglot-debug
+    ```
+
+3. Build the application using Maven:
+    ```bash
+    mvn clean package
+    ```
+4. Run this application with the following command:
+    ```bash
+    mvn exec:exec
+    ```
+
+## Debug the Application
+
+Working with a polyglot project in VS Code is simple just open this sample.
 It will be working out of the box with VS Code GraalVM extensions.
 
-Place breakpoints either in Java or JavaScript code.
+1. Place breakpoints either in Java or JavaScript code.
+
+2. To debug the project, go to __Run and Debug__ activity or simply press F5.
 
-To debug the project go to __Run and Debug__ activity or simply press F5.
-Choose **Launch Java 8+** as this is the Polyglot debugger provided by GraalVM extensions.
+3. Choose **Launch Java 8+** as this is the Polyglot debugger provided by the GraalVM extension.
 
 That is, the sample is running under debugger on GraalVM.
