-
-use SilverStripe\Control\HTTPApplication;
-use SilverStripe\Control\HTTPRequestBuilder;
-use SilverStripe\Core\CoreKernel;
-use SilverStripe\Core\Startup\ErrorControlChainMiddleware;
-
-require __DIR__ . '/vendor/autoload.php';
-
-// Build request and detect flush
-$request = HTTPRequestBuilder::createFromEnvironment();
-
-// Default application
-$kernel = new CoreKernel(BASE_PATH);
-$app = new HTTPApplication($kernel);
-$app->addMiddleware(new ErrorControlChainMiddleware($app));
-$response = $app->handle($request);
-$response->output();
-```

+file (e.g. a custom `main.php`, HTTP header configuration, deny file access),
+you'll need to manually reapply these to the copied default file.
