+# Development and testing
+
+## Building the Operator image
+
+From the root repo directory (ie `cd ..` from here), run:
+
+```
+make build-operator
+```
+
+You can build a test image by setting `ORG` and `TAG` build arguments, eg:
+
+```
+make build-operator ORG=mikeodigos TAG=dev
+```
+
+If you are on Mac and want to test this in an OpenShift cluster running on Linux, use the
+`make push-operator` command instead (which uses `docker buildx` to cross-compile).
+
+## Building the Operator Bundle
+
+For OpenShift, we need an Operator Bundle which is an image consisting of the manifests
+and metadata required to install the Operator.
+
+From this directory, run:
+
+```
+make generate manifests bundle
+```
+
+You can set your dev image by passing the `IMG` build arg:
+
+```
+make bundle IMG=docker.io/mikeodigos/odigos-operator:dev
+```
+
+Note that the fully-qualified domain is required (`docker.io`). This will rewrite the manifests
+with Kustomize to point to your docker image.
+
+Next, build the Bundle Image:
+
+```
+make build-bundle
+```
+
+Again, you can point to your image by setting `IMAGE_TAG_BASE`:
+
+```
+make build-bundle IMAGE_TAG_BASE=mikeodigos/odigos-operator VERSION=dev
+```
+
+This will build a new docker image for the bundle containing all the generated manifests.
+
+### Running in OpenShift
+
+To test in an OpenShift cluster, push the operator image and bundle image to your registry.
+
+Connect to the cluster with `oc login` and run:
+
+```
+operator-sdk run bundle <path to bundle image:tag>
+```
+
+Clean up with:
+
+```
+operator-sdk cleanup odigos-operator  --delete-all
+```
