+In this sample, you'll build a native GraalVM image for running web workloads in AWS Lambda.
+
+The sample contains a typical Spring MVC application with MVC controllers which will 
+The sample contains two functions - `uppercase` and `reverse` - so you can see how to route requests. A provided `RoutingFunction` will send messages to a handler function specified in a header named: `spring.cloud.function.definition` (demonstrated in the test section). The routing value can also be passed as an environment variable. If using API Gateway, you can pass this value as an HTTP header. 
+
+**Example function definition**
+```
+@Bean
+public Function<String, String> uppercase() {
+  return v -> {
+    System.out.println("Uppercasing " + v);
+    return v.toUpperCase();
+  };
+}
+```
+
+> Note: If your function takes a Spring Message as an input parameter (e.g., Function<Message, ..>), the Lambda Context object will be available in the message header `aws-context`. See [AWSLambdaUtils.java](https://github.com/spring-cloud/spring-cloud-function/blob/main/spring-cloud-function-adapters/spring-cloud-function-adapter-aws/src/main/java/org/springframework/cloud/function/adapter/aws/AWSLambdaUtils.java#L67C44-L67C55) for details.
+
+
+## To build the sample on macOS (Apple silicon arm64)
+
+You first need to build the function, then you will deploy it to AWS Lambda.
+
+### Step 1 - Build the native image
+
+Before starting the build, you must clone or download the code in **function-sample-aws-native**.
+
+1. Change into the project directory: `spring-cloud-function-samples/function-sample-aws-native`
+2. Run the following to build a Docker container image which will be used to create the Lambda function zip file. 
+   ```
+   docker build -t "al2-graalvm19:native-function" .
+   ```
+3. Start the container
+   ```
+   docker run -dit -v `pwd`:`pwd` -w `pwd` -v ~/.m2:/root/.m2 al2-graalvm19:native-function
+   ```
+4. In Docker, open the image terminal. 
+
+   > Your working directory should default to the project root. Verify by running `ls` to view the files.
+
+6. From inside the container, build the Lambda function:
+   ```
+   ./mvnw clean -Pnative native:compile -DskipTests
+   ```
+
+After the build finishes, you need to deploy the function.
+
+
+### Step 2 - Deploy your function
+
+You will first create the function, and then you will upload the zipped native image from the build process.
+
+**Create the function**
+1. Login to the **Amazon Web Services console**.
+2. Navigate to the **Lambda service**.
+3. Choose `Create Function`.
+4. For **function name**, enter `native-func-sample`.
+5. For runtime, select `Provide your own bootstrap on Amazon Linux 2`.
+6. For architecture, select `arm64`.
+7. Choose `Create Function` again.
+
+**Upload the zip image**
+1. Choose `Upload from`, then `.zip file`.
+2. From the `target` directory, select the .zip file created by the build.
+3. Wait for the image to upload.
+
+### Step 3 - Test your function
+
+Your test event will provide the information needed to select the `uppercase` or `reverse` handler functions.
+
+1. From the Lambda console, navigate to the `Test` tab. 
+2. For test data, enter the following JSON:
+   ```JSON
+   {
+       "payload": "hello",
+       "headers": {
+           "spring.cloud.function.definition": "uppercase"
+       }
+   }
+   ```
+3. Choose **Test**.
+   You should see uppercased output for the payload value: "HELLO" 
+
+4. Change the test data to the following JSON:
+   ```JSON
+   {
+       "payload": "hello",
+       "headers": {
+           "spring.cloud.function.definition": "reverse"
+       }
+   }
+   ```
+5. Choose **Test**.
+   You should see reversed output for the payload value: "OLLEH" 
+
+
+**Congratulations!** You have built and deployed a Graal native image to AWS Lambda.
