+## Response Middleware
+
+This package provides the final response for a chain of middleware using the “store” package.
+
+### `store_response`
+
+The `store_response` middleware uses the peer data stored in the peerStore to create a response for the request.
+
+### Important things to notice
+
+This middleware is very basic, and may not do everything that you require.
