+### Optionally: installing as a `clusterctl` plugin
+Typically the plugin is installed under `~/.krew/bin/kubectl-operator`, which would be present under your `$PATH` after correct `krew` installation. If you want to use plugin with `clusterctl`, you need to rename this file to be prefixed with `clusterctl-` instead, like so:
+```bash
+cp ~/.krew/bin/kubectl-operator ~/.krew/bin/clusterctl-operator
+```
+
+After that plugin is available to use as a `clusterctl` plugin:
+```bash
+clusterctl operator --help
+```

+## Upgrade
+
+To upgrade your plugin with the new release of `cluster-api-operator` you will need to run:

+```bash
+kubectl krew upgrade
