   # You create a new record that uses delegated typing by creating the delegator and delegatee at the same time,
   # like so:
   #
-  #   Entry.create! entryable: Comment.new(content: "Hello!"), creator: Current.user
+  #   Entry.create! entryable: Comment.new(content: "Hello!"), creator: Current.user, account: Current.account

   # If you need more complicated composition, or you need to perform dependent validation, you should build a factory
   # method or class to take care of the complicated needs. This could be as simple as:

   #   class Entry < ApplicationRecord
