 # Polyglot Chat Application
 
-This example demonstrates how to integrate Python on GraalVM with a Micronaut application.
-The application uses the nltk module to analyze text sentiment.
-The application uses the Gradle build tool.
+This example demonstrates how to integrate Python in a Micronaut Java application using the Gradle build tool.
+The application uses the [Natural Language Toolkit (nltk)](https://www.nltk.org/) module to analyze the sentiment of user input.
+The example also shows how to create a native executable from the application using GraalVM.

 The application can be compiled ahead-of-time to a native executable using GraalVM Native Image.
 The Python code must be copied to the _build/_ directory that is kept next to the native executable.
