+### Testing using a pre-built operator image from a remote registry
+You can run the testsuite using an already built operator image from a remote image registry. 
+
+To do this, you need to set `quarkus.container-image.build=false` and specify the desired image 
+you want to use by setting `quarkus.container-image.image=<your-image>:<your-tag>`
+
+#### Example:
+
+```bash
+ mvn clean verify \
+      -Dquarkus.container-image.build=false \
+      -Dquarkus.container-image.image=quay.io/keycloak/keycloak-operator:nightly \
