     System specs are RSpec's wrapper around Rails' own
     [system tests](https://guides.rubyonrails.org/testing.html#system-testing).
 
+    Feature specs are marked by `:type => :system` or if you have set
+    `config.infer_spec_type_from_file_location!` by placing them in
+    `spec/system`.

     System tests allow you to test user interactions with your application,
     running tests in either a real or a headless browser. System tests use
     Capybara under the hood.
