+### Is there any tooling that can help me find dockershim in use
+
+Yes! The [Detector for Docker Socket (DDS)][dds] is a kubectl plugin that you can
+install and then use to check your cluster. DDS can detect if active Kubernetes workloads
+are mounting the Docker Engine socket (`docker.sock`) as a volume.
+Find more details and usage patterns in the DDS project's [README][dds].
