+## Example dev workflow
+
+I've made changes to `pkg/controllers/raycluster_controller.go` and `pkg/controllers/raycluster_controller.go`. I've
+written unit tests and would like to test my changes using the unit tests as well as on an OpenShift cluster which I
+have access to.
+
+1. Ensure the unit tests you've written are passing and you haven't introduced any regressions
+   1. run `make test-unit`
+1. build and push image
+   1. `make image-build -e IMG=<image-repo/image-name:image-tag>`
+   1. `make image-push -e IMG=<image-repo/image-name:image-tag>`
+1. Login to your OpenShift cluster via `oc login --token=... --server=...`
+1. deploy ODH/RHOAI if necessary
+   1. for the latest releases
+      1. run `make delete-all-in-one -e USE_RHOAI=<true|false>` **if** you would like to run on a fresh ODH/RHOAI deployment
+      1. run `make all-in-one -e USE_RHOAI=<true|false>` to deploy new instance of ODH/RHOAI
+   1. otherwise follow the dev guides found in
+    [ODH](https://github.com/opendatahub-io/opendatahub-operator?tab=readme-ov-file#deployment) and
+    [RHOAI](https://gitlab.cee.redhat.com/data-hub/olminstall) (Red Hat internal only)
+      1. run `make install-nfd-operator`, `make install-service-mesh-operator`, `make install-ai-platform-operator`, `make install-nvidia-operator` to ensure all dependent operators are also installed
+1. navigate to the DataScienceCluster resource and set `.spec.components.codeflare.managementState` to `Removed`
+1. run `make deploy -e IMG=<image-repo/image-name:image-tag>`
+
+Your dev image should now be deployed in the cluster
