+# Use Gradle to Build a Java Application from a Java Application
+
+The demo application simulates the traditional [fortune](https://en.wikipedia.org/wiki/Fortune_(Unix)) Unix program.
+The data for the fortune phrases is provided by [YourFortune](https://github.com/your-fortune).
+
+The project uses the [Gradle plugin for GraalVM Native Image building](https://graalvm.github.io/native-build-tools/latest/gradle-plugin.html).
+
+## Run the Demo
+
+1. Run the application on JVM:
+    ```bash 
+    ./gradlew run
+    ```
+2. Build a native executable:
+    ```bash 
+    ./gradlew nativeRun
+    ```
+    The `nativeRun` task compiles the application, invokes `nativeCompile`, and then runs the executable. 
+3. Re-run the application from the native executable:
+    ```bash
+    ./build/native/nativeCompile/fortune
+    ```
+Alternatively, you can execute `./run.sh` to build and run the application.
