+                    Most of our modules and source code have been consolidated into two maven modules:  keycloak-server-spi and
+                    keycloak-services.  SPI interfaces are in server-spi, implementations are in keycloak-services.
+                    All JPA dependent modules have been consolidated under keycloak-model-jpa.  Same goes
+                    with mongo and infinispan under modules keycloak-model-mongo and keycloak-model-infinispan.
