 ## Customization
 
 If you want to use other foreign key name, you can define it by `:foreign_key` option.
 
 ```ruby
-resonate :user, with: :post, by: :like, foreign_key: :post_id # Default is `:target_post_id`
+resonate :user,
+  target: :post,
+  action: :like,
+  foreign_key: { target: :post_id } # Default key is `:target_post_id`
 ```
