 This example demonstrates how to integrate Python on GraalVM with a Micronaut application.
 The application uses the Gradle build tool.
 
-### Prerequisites
-- [Native Image](https://www.graalvm.org/latest/reference-manual/native-image/)
-- [Python support](https://www.graalvm.org/latest/reference-manual/python/)
+## Preparation`
 
-## Preparation
-
-1. Download the latest GraalPy as described on [https://www.graalvm.org/python/](https://www.graalvm.org/python/). For example on Linux:
+1. Download or clone GraalVM demos repository and navigate into the `polyglot-chat-app` directory:
+    ```bash
+    git clone https://github.com/graalvm/graalvm-demos
+    ```
     ```bash
-    wget https://github.com/oracle/graalpython/releases/download/graal-23.1.1/graalpy-23.1.1-linux-amd64.tar.gz

+   tar xzf graalpy-23.1.1-linux-amd64.tar.gz
+   ``
+
+3. Create a virtual environment for this demo in the _resources_ directory, and install the required packages:
    ```bash
    graalpy-23.1.1-linux-amd64/bin/graalpy -m venv src/main/resources/venv
+   ```
+   ```bash
    src/main/resources/venv/bin/graalpy -m pip install nltk
    ```
+   ```bash
+   src/main/resources/venv/bin/graalpy -c "import nltk; nltk.download('vader_lexicon')"
+   ```
 
-3. Optional: Download and install GraalVM JDK for Java 21 or later to run Python with runtime compilation and to build a native image.
-   The demo will work on any OpenJDK distribution, but will be much faster on GraalVM JDK.
