+= http-log
+
+This is a basic hello world example that uses CDI and JAX-RS to setup
+a REST service and a Camel route to service HTTP traffic.
+
+TIP: Check the
https://camel.apache.org/camel-quarkus/latest/first-steps.html[Camel Quarkus
User guide] for prerequisites
+and other general information.
+
+== Start in the Development mode
+
+[source,shell]
+----
+$ mvn clean compile quarkus:dev -DnoDeps
+----
+
+The above command compiles the project, starts the application and lets the
Quarkus tooling watch for changes in your
+workspace. Any modifications in your project will automatically take effect in
the running application.
+
+TIP: Please refer to the Development mode section of
+https://camel.apache.org/camel-quarkus/latest/first-steps.html#_development_mode[Camel
Quarkus User guide] for more details.
+
+You can from a web browser call the two services via
+
+- http://localhost:8080/hello
+- http://localhost:8080/camel/hello
+
+There is also health check and metrics available from the following urls:
+
+- http://localhost:8080/health
+- http://localhost:8080/metrcis
+
+=== Package and run the application
+
+Once you are done with developing you may want to package and run the
application.
+
+TIP: Find more details about the JVM mode and Native mode in the Package and
run section of
+https://camel.apache.org/camel-quarkus/latest/first-steps.html#_package_and_run_the_application[Camel
Quarkus User guide]
+
+==== JVM mode
+
+[source,shell]
+----
+$ mvn clean package
+$ java -jar target/*-runner.jar
+...
+[io.quarkus] (main) Quarkus 0.23.2 started in 1.163s. Listening on:
http://[::]:8080
+----
+
+==== Native mode
+
+IMPORTANT: Native mode requires having GraalVM and other tools installed.
Please check the Prerequisites section
+of
https://camel.apache.org/camel-quarkus/latest/first-steps.html#_prerequisites[Camel
Quarkus User guide].
+
+To prepare a native executable using GraalVM, run the following command:
+
+[source,shell]
+----
+$ mvn clean package -Pnative
+$ ./target/*-runner
+...
+[io.quarkus] (main) Quarkus 0.23.2 started in 0.013s. Listening on:
http://[::]:8080
