+Quarkus RabbitMQ 1.0 Quickstart
+============================
+
+This project illustrates how you can interact with RabbitMQ using MicroProfile Reactive Messaging.
+The complete instructions are available on https://quarkus.io/guides/rabbitmq.
+
+## Start the application in dev mode
+
+In a first terminal, run:
+
+```bash
+> mvn -f rabbitmq-quickstart-producer quarkus:dev
+```
+
+In a second terminal, run:
+
+```bash
+> mvn -f rabbitmq-quickstart-processor quarkus:dev
+```  
+
+Then, open your browser to `http://localhost:8080/quotes.html`, and click on the "Request Quote" button.
+
+## Build the application in JVM mode
+
+To build the applications, run:
+
+```bash
+> mvn -f rabbitmq-quickstart-producer package
+> mvn -f rabbitmq-quickstart-processor package
+```
+
+Because we are running in _prod_ mode, we need to provide an RabbitMQ broker.
+The [docker-compose.yml](docker-compose.yml) file starts the broker and your application.
+
+Start the broker and the applications using:
+
+```bash
+> docker compose up --build
+```
+
+Then, open your browser to `http://localhost:8080/quotes.html`, and click on the "Request Quote" button.
+
+
+## Build the application in native mode
+
+To build the applications into native executables, run:
+
+```bash
+> mvn -f rabbitmq-quickstart-producer package -Pnative  -Dquarkus.native.container-build=true
+> mvn -f rabbitmq-quickstart-processor package -Pnative -Dquarkus.native.container-build=true
+```
+
+The `-Dquarkus.native.container-build=true` instructs Quarkus to build Linux 64bits native executables, who can run inside containers.  
+
+Then, start the system using:
+
+```bash
+> export QUARKUS_MODE=native
+> docker compose up
+```
+Then, open your browser to `http://localhost:8080/quotes.html`, and click on the "Request Quote" button.
