 ## Overview
 
-Datadog provides monitoring and insights into infrastructure and application performance across your entire stack. The AWS Distro for Open Telemetry includes the [Datadog exporter](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/master/exporter/datadogexporter), which takes OpenTelemetry data (metrics and traces) collected by the ADOT Collector and forwards it on to Datadog. From there, you can use Datadog tools and dashboards to analyze and solve performance problems in your distributed apps.

 ## Specifying resource attributes
 
-On each OpenTelemetry-instrumented application, set the resource attributes `development.environment`, `service.name`, and `service.version` using [the language's SDK](https://opentelemetry.io/docs/). As a fall-back, you can also configure hostname (optionally) at the collector level for [unified service tagging](https://docs.datadoghq.com/getting_started/tagging/unified_service_tagging) by following the [example configuration file](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/master/exporter/datadogexporter/example/config.yaml). If you don't specify the hostname explicitly, the exporter attempts to get an automatic default by checking the following sources in order, falling back to the next one if the current one is unavailable or invalid:
