Usage Help!

Hey,
I came across this repo and I just wanted to confirm on how to use/integrate the cloudwatch and dropwizard metrics using your repo.
From the looks of it,

1. I have to add dependency,

<groupId>io.github.azagniotov</groupId>
<artifactId>dropwizard-metrics-cloudwatch</artifactId>
<version>2.0.5</version>

2. Change the config.yml file as illustrated.
3. Build the report and start it inside the service.

new CloudWatchReporterBuilder()
                .withNamespace(ExampleMetrics.class.getSimpleName())
                .withRegistry(registry)
                .build()
                .start(1, TimeUnit.MINUTES);

I tried with first two steps and didn't work.
PS: I didn't provide the AWS secret keys. So, that is why the metrics are not being reported to that AWS account.
Please help
