+### Building Native Executables
+
+The project supports building native executables using GraalVM. This creates a standalone binary with faster startup time and lower memory footprint.
+
+#### Prerequisites
+
+1. Install GraalVM (recommended: GraalVM 22.3 or later)
+2. Set `GRAALVM_HOME` or `JAVA_HOME` to point to your GraalVM installation
+3. Install the native-image tool:
+   ```shell
+   gu install native-image
+   ```
+
+#### Build Native Executable
+
+To build a native executable, run:
+
+```shell
+./mvnw clean package -Pnative
+```
+
+The native executable will be created in `target/jvm` (or `target/jvm.exe` on Windows).
