+# Login
+The login component is a local Keycloak instance. In the future will be replaced by the central keycloak instance
+or maybe can be used to add local identity providers to the bridgehead or just to simplify the configuration of
+the central keycloak instance for the integration of every new bridgehead.
+The basic configuration of our Keycloak instance is contained in a small json file.
+
+### Teiler User
+Currently, the local keycloak is used by the teiler. There is a basic admin user in the basic configuration of keycloak.
+The user can be configured with the environment variables TEILER_ADMIN_XXX.
+
+## Login-DB
+Keycloak requires a local database for its configuration. However, as we use an initial json configuration file, if no
+local identity provider is configured nor any local user, theoretically we don't need a volume for the login.
