+4. Google redirects user back to Redmine, where the Google OAuth plugin's controller takes over.
 
-User goes to the login page (sign in) and clicks the button with Google image. The plugin redirects him to Google where user enters his the еmail & password from Google. Google redirects user back to plugins controller. Then the following cases:
-1. If auto registration is enabled, user is redirected to 'my/page'
-2. In other case user account is created and waited for admin activation
+One of the following cases will occur:
+1. If self-registration is enabled (Under Administration > Settings > Authentication), user is redirected to 'my/page'
+2. Otherwse, the an account is created for the user (referencing their Google OAuth2 ID). A Redmine administrator must activate the account for it to work.
