 **Note**: Be sure that the middleware is high enough up in your stack that all feature checks are wrapped.
 
 **Also Note**: If you haven't setup a default instance, you can pass the instance to `SetupEnv` as `Memoizer` uses whatever is setup in the `env`:
 
 ```ruby
-require 'flipper/middleware/setup_env'
-require 'flipper/middleware/memoizer'
 config.middleware.use Flipper::Middleware::SetupEnv, -> { Flipper.new(...) }
