 Oaken is a new take on development and test data management for your Rails app. It blends the stability and storytelling from Fixtures with the dynamicness of FactoryBot/Fabricator.

 This will convert anything in test/fixtures to db/seeds. E.g. `test/fixtures/users.yml` becomes `db/seeds/users.rb`.
 
+### Disable fixtures
+
+IF you've fully converted to Oaken you may no longer want fixtures when running Rails' generators,
+so you can disable generating them in `config/application.rb` like this:
+
+```ruby
+module YourApp
+  class Application < Rails::Application
+    # We prefer Oaken to fixtures, so we disable them here.
+    config.app_generators { _1.test_framework _1.test_framework, fixture: false }
+  end
+end
+```
+
+The `test_framework` repeating is to preserve `:test_unit` or `:rspec` respectively.
+
+> [!NOTE]
+> If you're using `FactoryBot` as well, you don't need to do this since it already replaces fixtures for you.
