 In the same spirit as [building local binaries](#building-local-binaries), you can build local docker images instead of local binaries.
 
-Currently, we are supporting two build systems:
-- [Building local images with docker](#building-local-images-with-docker)
-- [Building local images with ko](#building-local-images-with-ko)

-> **Note**: We started with `docker` and are progressively moving to `ko`.
-
-As the `ko` based build system matures, we will deprecate and remove `docker` based builds.
-
-Choosing between `docker` and `ko` boils down to a prefix when invoking `make` targets. 
-For example:
-- `make docker-build-kyverno` creates a docker image using the `docker` build system
-- `make ko-build-kyverno` creates a docker image using the `ko` build system

-#### Building kyvernopre image locally
-
-To build `kyvernopre` image on your local system, run:

-The resulting image should be available locally, named `ghcr.io/kyverno/kyvernopre` (by default, if `REGISTRY` environment variable was not set).

-### Switching between docker and ko
-
-The sections above cover building images with `docker` or `ko` by prefixing build commands (`docker-build-*` or `ko-build-*`).
-
-You can achieve the same results by setting the `BUILD_WITH` environment variable, and invoke a generic `image-build-*` target:

 ## Pushing images
 
 Pushing images is very similar to [building local images](#building-local-images), except that built images will be published on a remote image registry.
 
-Currently, we are supporting two build systems:

 When pushing images you can specify the registry you want to publish images to by setting the `REGISTRY` environment variable (default value is `ghcr.io`).
 
 <!-- TODO: explain the way images are tagged. -->
 
-### Pushing images with docker
-
-Authenticating to the remote registry is not done automatically in the `Makefile`.

-You need to be authenticated before invoking targets responsible for pushing images.
-
-> **Note**: You can push all images at once by running `make docker-publish-all` or `make docker-publish-all-dev`.
