+The `{keycloak-image}` image which contains a Keycloak distribution powered by Quarkus is used to start a container by default.
 `quarkus.keycloak.devservices.image-name` can be used to change the Keycloak image name.
 For example, set it to `quay.io/keycloak/keycloak:19.0.3-legacy` to use a Keycloak distribution powered by WildFly.
 Be aware that a Quarkus-based Keycloak distribution is only available starting from Keycloak `20.0.0`.
