 In the CI system we set up a pre-configured minikube cluster that is then used
 for the tests, as seen in [ci-e2e.sh](../../hack/ci-e2e.sh). This allows us to
 have control over the network and have a static configuration for Ironic and the

+Baremetal Operator. The script creates a VM to represent a BareMetalHost,
+and configures either VBMC or sushy-tools to be used as BMC. This script can be
+configured to run either [E2E upgrade tests](upgrade_test.go), or the "normal"
+E2E tests set (all tests except the upgrade ones) by exporting the `GINKGO_FOCUS`
+env var. If "upgrade" is found as a part of `GINKGO_FOCUS`, ONLY the upgrade tests
+will be run, otherwise the upgrade tests are skipped (other tests in `GINKGO_FOCUS`
+or `GINKGO_SKIP` will be kept as-is).
+
+Here is how to run the E2E upgrade tests:
+
+```bash
+export GINKGO_FOCUS="upgrade"
+./hack/ci-e2e.sh
+```
 
 It is also possible to run the tests with the fixture provider instead of
-Ironic, but please note that it is quite questionable to call this configuration
-"end to end". This is how to run the e2e test suite with the fixture provider:
+Ironic. Without any changes, the whole suite (including upgrade tests) will be run.
