+== Running the application in dev mode
 
 You can run your application in dev mode that enables live coding using:
-```shell script
+
+[source,shell]
+----
 mvn compile quarkus:dev
-```
+----
 
-> **_NOTE:_**  Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

-## Packaging and running the application
+== Packaging and running the application
 
 The application can be packaged using:
-```shell script
+
+[source,shell]
+----
 mvn package
-```
+----
+
 It produces the `quarkus-run.jar` file in the `target/quarkus-app/` directory.
 Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/quarkus-app/lib/` directory.
 
 The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`.
 
 If you want to build an _über-jar_, execute the following command:
-```shell script
+
+[source,shell]
+----
 mvn package -Dquarkus.package.type=uber-jar
-```
+----
 
 The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`.

 You can then execute your native executable with: `./target/code-with-quarkus-1.0.0-SNAPSHOT-runner`
