-## Validation
-
-It is recommended that you add a validation to ensure that the author do not vote multiple times on the same resource and its scope.
-This validation is not inside the gem since you could want make your own custom validation.
-
-```ruby
-validates :author_id, uniqueness: {
-  case_sensitive: false,
-  scope:          %i[author_type resource_id resource_type scopeable_id scopeable_type]
-}
