 Alternatively, instead of specifying variables on the command line,
 you can edit the Makefile to permanently change parameter defaults
 like name of the image or namespace where the operator is deployed.

+## Image variants
+
+Node-Feautre-Discovery-Operator currently offers two variants
+of the container image. The "full" variant is currently
+deployed by default.
+
+### Full
+
+This image is based on
+[debian:buster-slim](https://hub.docker.com/_/debian) and contains a full Linux
+system for doing live debugging and diagnosis of the operator.
+
+### Minimal
+
+This is a minimal image based on
+[gcr.io/distroless/base](https://github.com/GoogleContainerTools/distroless/blob/master/base/README.md)
+and only supports running statically linked binaries.
+
+The container image tag has suffix `-minimal`
+(e.g. `{{ site.container_image }}-minimal`)
+
 ## Verify
 
 The Operator will deploy NFD based on the information
