+#### Enable running container against OpenShift Local
+
+While running the test suite as a container, you can enable the container to be able to reach the local CRC instance by setting:
+
+```shell
+export TNF_ENABLE_CRC_TESTING=true
+```
+
+This utilizes the `--add-host` flag in Docker to be able to point `api.crc.testing` to the host gateway.
+
 ### Exceptions
 
 These options allow adding exceptions to skip several checks for different resources. The exceptions must be justified in order to pass the CNF Certification.
