 ## (go/v2, go/v3, ansible/v1, helm/v1) Changed `BUNDLE_IMG` and added `IMAGE_TAG_BASE` Makefile variables
 
 The following Makefile changes were made to allow `make bundle-build bundle-push catalog-build catalog-push` and encode image repo/namespace information in the Makefile by default:
-```diff +IMAGE_TAG_BASE ?= <registry>/<operator name> + -BUNDLE_IMG ?= controller-bundle:$(VERSION) +BUNDLE_IMG ?= $(IMAGE_TAG_BASE)-bundle:v$(VERSION) ```
+```diff
++IMAGE_TAG_BASE ?= <registry>/<operator name>
++ 
+-BUNDLE_IMG ?= controller-bundle:$(VERSION) +BUNDLE_IMG ?= $(IMAGE_TAG_BASE)-bundle:v$(VERSION)
+```
+
 For example, if `IMAGE_TAG_BASE ?= foo/bar-operator` then running `make bundle-build bundle-push catalog-build catalog-push` would build `foo/bar-operator-bundle:v0.0.1` and `foo/bar-operator-catalog:v0.0.1` then push them to the `docker.io/foo` namespaced registry.
