 ``CAS_FEDERATE_PROVIDERS`` is a dictionnary using provider names as key and a tuple
-(cas address, cas version protocol) as value.
+(cas address, cas version protocol, provider verbose name) as value.
 
 In federation mode, ``django-cas-server`` build user's username as follow:
 ``provider_returned_username@provider_name``.
 You can choose the provider returned username for ``django-cas-server`` and the provider name
 in order to make sense.
 
+The "provider verbose name" is showed on the select menu of the login page.
+
 
 Then using federate mode, you should add one command to a daily crontab: ``cas_clean_federate``.
 This command clean the local cache of federated user from old unused users.
