	### Verify targets
	#
	# verify_lint       - run 'lint' targets
	# verify_unit       - run unit tests
	# verify_deps       - verifiy vendor/ and Gopkg.lock is up to date
	# verify_codegen    - verify generated code, including 'static deploy manifests', is up to date
	# verify_docs       - verify the generated reference docs for API types is up to date
	# verify_chart      - runs Helm chart linter (e.g. ensuring version has been bumped etc)
	#
	### Generate targets
	#
	# generate          - regenerate all generated files
	#
	### Build targets
	#
	# controller        - build a binary of the 'controller'
	# webhook           - build a binary of the 'webhook'
	# acmesolver        - build a binary of the 'acmesolver'
	# e2e_test          - builds and runs end-to-end tests.
	#                     NOTE: you probably want to execute ./hack/ci/run-e2e-kind.sh instead of this target
	# images            - builds docker images for all of the components, saving them in your Docker daemon
	# images_push       - pushes docker images to the target registry
	#
	# Image targets can be run with optional args DOCKER_REPO and DOCKER_TAG:
	#
	#     make images DOCKER_REPO=quay.io/yourusername DOCKER_TAG=experimental-tag
