+# DataDog Agent Service
+
+## Info
+Based on the official [Datadog Agent Docker image](github.com/DataDog/docker-dd-agent) with a few changes to the init script to better support the Rancher environment.
+
+## Notable Improvements
+* Hostname reported to DataDog is the actual name of the host (per Rancher Metadata service)
+* User can specify host labels which will be sent to DataDog as key:value tags for the host
+* User can either deploy the DogStat Agent globally on every host or deploy a single instance of a standalone DogStatsD
+* The later is useful if you just want a StatsD aggregator to which other services can send metrics
