+==== Defining a 'logout' action
+
+Your Rails application's controller(s) will probably have some sort of logout function. In it you will likely want reset the 
+user's session for your application, and then redirect to the CAS server's logout URL. Here's an example of how to do this:
+
+  def logout
+  	reset_session
+  	redirect_to CAS::Filter.logout_url(self, request.referer)
+  end
+
+==== Gatewayed authentication
+
+RubyCAS-Client supports gatewaying as of version 1.1.0. Gatewaying allows for optional CAS authentication, so that users who
+already have a pre-existing CAS SSO session will be automatically authenticated for the gatewayed service, while those who
+do not, will be allowed to access the service without authentication. This is useful for example when you want to show
+some additional private content on a homepage to authenticated users, but also want unauthenticated users to be able to
+access the page without first logging in.
+
+For more information on using gatewaying, see CAS::GatewayFilter.

 ==== How to act as a CAS proxy
 
 CAS 2.0 has a built-in mechanism that allows a CAS-authenticated application to pass on its authentication to other applications.
 An example where this is useful might be a portal site, where the user logs in to a central website and then gets forwarded to
 various other sites that run independently of the portal system (but are always accessed via the portal). The exact mechanism
