-Check that `be_nil` is used instead of `be(nil)`.
+Ensures a consistent style is used when matching `nil`.
+
+You can either use the more specific `be_nil` matcher, or the more
+generic `be` matcher with a `nil` argument.
 
-RSpec has a built-in `be_nil` matcher specifically for expecting `nil`.
-For consistent specs, we recommend using that instead of `be(nil)`.
+This cop can be configured using the `EnforcedStyle` option
