anchor.diff:  
   First, we need a new project. Create a new project with the following command:
   
  -[source]
  +[source, subs=attributes+]
   ----
  -mvn org.jboss.shamrock:shamrock-maven-plugin:1.0.0.Alpha1-SNAPSHOT:create \
  +mvn org.jboss.shamrock:shamrock-maven-plugin:{shamrock-version}:create \
       -DprojectGroupId=org.acme \
       -DprojectArtifactId=application-configuration \
       -DclassName="org.acme.config.GreetingResource" \
  
positive.code: 
  We need to create the file providing the values.
  By default, Shamrock reads `META-INF/microprofile-config.properties`.
  Create the `src/main/resources/META-INF/microprofile-config.properties` with the following content:
  
  [source]
  ----
  
negative.code: greeting.message = hello
  greeting.name = shamrock
  ----
  
  Once set, check the application with:
  
  [source]
  ----
  $ curl  http://localhost:8080/greeting
  hello shamrock!
  ----
  
  TIP: If the application requires configuration values and these values are not set, an error is thrown.
  So you can quickly now when your configuration is complete.
