 ## Read-only hashing methods
 
 The following methods are supported **read only**.
+If you plan to use SOGo (as per default), you need a SOGo compatible hashing method. Please see the note at the bottom of this page how to update the view if necessary.
+With SOGo disabled, all hashing methods below will be able to be read by mailcow and Dovecot.
