 This example shows how to build a simple [Micronaut](https://micronaut.io/) REST application using the [GraalVM Native Image Layers](https://github.com/oracle/graal/blob/master/substratevm/src/com.oracle.svm.core/src/com/oracle/svm/core/imagelayer/NativeImageLayers.md) feature.
 
+### Prerequisites
+- SDKMAN! (for installing Micronaut CLI)
+- Latest GraalVM 25.1 EA build (with Native Image support)
