 To provide Shibboleth attributes via environment variables, we can not use proxy_balancer base approach. Currently we can realize it by using Phusion Passenger as an application container. An example construction pattern is shown in presence_checker application (https://github.com/toyokazu/presence_checker/).
 
 ### development mode
 
-When you deploy a new application, you may want to confirm the assumed attributes are correctly provided by Shibboleth SP. OmniAuth Shibboleth strategy provides a confirmation option :dev_mode. If you set :dev_mode true, you can see the environment variables provided at the /auth/shibboleth/callback uri.
