	### Verify targets
	#
	# verify             - runs all test targets (bazel test //...)
	# verify_deps        - ensure go module files are up to date (hack/update-deps.sh)
	# verify_chart       - runs Helm chart linter
	#
	### Generate targets
	#
	# generate           - regenerate all generated files
	#
	### Build targets
	#
	# controller         - build a binary of the 'controller'
	# cainjector         - build a binary of the 'cainjector'
	# 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 APP_VERSION=v0.11.0-dev.my-feature
