-==== Quick-start Spring CLI Example
-You can use the following web application to test your installation.
-To start, create a file called `app.groovy`, as follows:
-
-[source,groovy,indent=0,pending-extract=true,subs="verbatim"]
-----
-	@RestController
-	class ThisWillActuallyRun {
-
-		@RequestMapping("/")
-		String home() {
-			"Hello World!"
-		}
-
-	}
-----
-
-Then run it from a shell, as follows:
-
-[source,shell,indent=0,subs="verbatim"]
-----
-	$ spring run app.groovy
-----
-
-NOTE: The first run of your application is slow, as dependencies are downloaded.
-Subsequent runs are much quicker.
-
-Open `http://localhost:8080` in your favorite web browser.
-You should see the following output:
-
-[indent=0]
-----
-	Hello World!
-----
