+### Configure Default Options
+
+If you want to use a configuration option globally in your application
+as a default, you can set up the following in your application.rb or in
+an initializer:
+```ruby
+  # config/initializers/acts_as_paranoid.rb:
+  Rails.application.config.acts_as_paranoid_default_options = {
+    column: 'deleted',
+    recover_dependent_associations: false,
+    double_tap_destroys_fully: false,
+  }
+```
+This overrides the defaults set by the gem but in turn can still be overriden
+when defining a class as `acts_as_paranoid`.
