+You can choose whether or not users can login with an email address that is not the primary email address.
+
+```ruby
+Devise::MultiEmail.configure do |config|
+  # Default is `false`
+  config.only_login_with_primary_email = true
+end
+```
+
+The `autosave` is automatically enabled on the `emails` association by default. This is to ensure the `primary`
+flag is persisted for all emails when the primary email is changed. When `autosave` is not enabled on the association,
+only new emails are saved when the parent (e.g. `User`) record is saved. (Updates to already-persisted email records
+are not saved.)
+
+If you don't want `autosave` to be enabled automatically, you can disable this feature. What this will do is
+enable alternative behavior, which adds an `after_save` callback to the parent record and calls `email.save` on each email
+record where the `primary` value has changed.
+
+```ruby
+Devise::MultiEmail.configure do |config|
+  # Default is `true`
+  config.autosave_emails = false
+end
+```

 ### Configure custom association names
 
 You may not want to use the association `user.emails` or `email.users`. You can customize the name of the associations used. Add your custom configurations to an initializer file such as `config/initializers/devise-multi_email.rb`.
 
 _Note: model classes are inferred from the associations._
