+  pros 'Allows to soft-delete `ActiveRecord` records.'
+  pros 'Does not pollute `ActiveRecord::Base` automatically. You can include `Discard::Model` into any model you want.'
+  pros 'Does not override any existing `ActiveRecord` methods.'
+
+  comment "We've used [acts_as_paranoid](https://github.com/ActsAsParanoid/acts_as_paranoid) and [paranoia](https://github.com/rubysherpas/paranoia) in the past. The both are great libraries, however they both override some `ActiveRecord` methods. Besides this you can run into issues when working with associations. Discard seems to be a better alternative."
