### Yaml Configuration Format

The Yaml Configuration Format extends the Vert.x Configuration Retriever and provides the support for the Yaml Configuration Format format.

#### Using the Yaml Configuration Format

To use the Yaml Configuration Format, add the following dependency to the dependencies section of your build descriptor:

- Maven (in your `pom.xml`):

    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config-yaml</artifactId>
      <version>3.4.0</version>
    </dependency>
    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config</artifactId>
      <version>3.4.0</version>
    </dependency>

- Gradle (in your `build.gradle` file):

    compile 'io.vertx:vertx-config:3.4.0'
    compile 'io.vertx:vertx-config-yaml:3.4.0'

#### Configuring the store to use YAML

Once added to your classpath or dependencies, you need to configure the `ConfigRetriever` to use this format:

    def store = [
      type:"file",
      config:[
        path:"my-config.conf",
        format:"hocon"
      ]
    ]

    def retriever = ConfigRetriever.create(vertx, [
      stores:[
        store
      ]
    ])

You just need to set `format` to `yaml`.
