+
+Test project for GraalVM support
+
+Requirements : 
+
+- GraalVM 21+
+
+## Quickstart
+
+1. Build the main Apache FreeMarker proejct : 
+
+```shell
+./gradlew "-Pfreemarker.signMethod=none" "-Pfreemarker.allowUnsignedReleaseBuild=true" clean build
+```
+
+2. Build the test module native image with GraalVM : 
+
+```shell
+./gradlew :freemarker-test-graalvm-native:nativeCompile 
+```
+
+3. Run the project :
+
+```shell
+./freemarker-test-graalvm-native/build/native/nativeCompile/freemarker-test-graalvm-native 
+```
+
+Output should be similar to : 
+
+```txt
+INFO: name : FreeMarker Native Demo, version : 2.3.35-nightly
+Jan 15, 2025 4:28:19 PM freemarker.log._JULLoggerFactory$JULLogger info
+INFO: result :
+<html>
+    <head>
+        <title>Hello : FreeMarker GraalVM Native Demo</title>
+    </head>
+    <body>
+        <h1>Hello : FreeMarker GraalVM Native Demo</h1>
+        <p>Test template for Apache FreeMarker GraalVM native support (2.3.35-nightly)</p>
+    </body>
+</html>
+```
+
+## CI (GitHub workflow)
+
+GraalVM native test for this module is included in the GitHub  [CI](../.github/workflows/ci.yml) worflow.
