Your application can use the MicroProfile Config or
 Helidon Config (or both). MicroProfile Config offers portability to other
 MicroProfile servers. Helidon Config supports a full tree structure, including repeating
 elements.

== Configuring the Application

You can inject values that the application can access from both MicroProfile Config and from
Helidon Config.
