+1. Install & configure the Datadog Trace Agent (>= 5.21.1).
+2. Set the `IMGPROXY_DATADOG_ENABLE` environment variable to `true`.
 3. Configure the Datadog tracer using `ENV` variables provided by [the package](https://github.com/DataDog/dd-trace-go):
 
-    * `DD_AGENT_HOST` – sets the address to connect to for sending metrics to the Datadog Agent. Default: `localhost`
-    * `DD_TRACE_AGENT_PORT` – sets the Datadog Agent Trace port. Default: `8126`
-    * `DD_DOGSTATSD_PORT` – set the DogStatsD port. Default: `8125`
-    * `DD_SERVICE` – sets desired application name. Default: `imgproxy`
-    * `DD_ENV` - sets the environment to which all traces will be submitted. Default: empty
-    * `DD_TRACE_SOURCE_HOSTNAME` - allows specifying the hostname with which to mark outgoing traces. Default: empty
-    * `DD_TRACE_REPORT_HOSTNAME` - when `true`, sets hostname to `os.Hostname()` with which to mark outgoing traces. Default: `false`
-    * `DD_TAGS` - sets a key/value pair which will be set as a tag on all traces. Example: `DD_TAGS=datacenter:njc,key2:value2`. Default: empty
-    * `DD_TRACE_ANALYTICS_ENABLED` - allows specifying whether Trace Search & Analytics should be enabled for integrations. Default: `false`
-    * `DD_RUNTIME_METRICS_ENABLED` - enables automatic collection of runtime metrics every 10 seconds. Default: `false`
-    * `DD_TRACE_STARTUP_LOGS` – causes various startup info to be written when the tracer starts. Default: `true`
-    * `DD_TRACE_DEBUG` – enables detailed logs. Default: `false`
