-# 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
-

+# DataDog Agent & DogStatsD
+
+This service uses the [official](https://www.github.com/DataDog/docker-dd-agent) Datadog Agent image and a sidekick data volume containing a customized entrypoint script for improved integration with the Rancher environment.
+
+* The `hostname` reported to DataDog is the actual name of the host
+* You may specify `host labels` which are used as DataDog tags
+* Service will be deployed globally by default so that every host is monitored by a `DataDog Agent`
+* Alternatively you may deploy just a single `DogStatsD` instance which then acts as a metrics aggregator for other services
