+# Enrich from Kubernetes
+
+This is the e2e test for the Collector use-case:
+[Enrich from Kubernetes](https://docs.dynatrace.com/docs/shortlink/otel-collector-cases-k8s-enrich).
+
+## Requirements to run the tests
+
+- Docker
+- Kind
+
+The tests require a running Kind k8s cluster. During the tests,
+a Dynatrace distribution of the OpenTelemetry Collector is deployed
+on the k8s cluster with configurations as per the Dynatrace documentation page.
+
+Traces are generated and sent to the Collector, which then
+exports to the test where the k8s attributes are asserted on the
+received traces.
