+== Camel-K-runtime Java Example for kafka consumer to AWS S3
+
+This example shows the usage of Camel-k-runtime for kafka consumer to AWS S3
+
+The route involves kafka and aws2-s3 component
+
+=== Setup
+
+You'll need to have a kafka instance running on your machine or in docker.
+You'll need AWS Credentials.
+
+=== How to run
+
+You have two ways of doing this.
+
+First approach:
+
+ mvn exec:exec
+
+This approach will pack and run a camel-quarkus runner.
+
+Second approach
+
+ mvn clean package
+ export CAMEL_K_CONF=${project.basedir}/data/application.properties
+ export CAMEL_K_ROUTES=file:${project.basedir}/data/MyRoutes.java
+ java -jar target/camel-k-runtime-example-java-runner.jar
+
+You should get the following output in both cases
