+### Option: Generated scope
+
+By default, this adds a scope for each timestamp column:
+
+```ruby
+Post.published
+#=> [#<Post published_at: Fri, 04 Sep 2020 18:16:38 UTC +00:00>]
+
+Post.published(false)
+#=> [#<Post published_at: nil>]
+```
+
+To skip defining the scope, set the `:scopes` option to `false` when calling `boolean_timestamps`.
+
+```ruby
+class Post < ActiveRecord::Base
+  boolean_timestamps :published_at, scopes: false
+end
+```
+```ruby
+Post.respond_to?(:published)
+#=> false
+```
+
