 - The `middlewareModule` is an SDK module that ensures communication with the Server Middleware. It takes the `UnifiedEndpoints` type as a generic parameter. The `UnifiedEndpoints` type is a type that represents the endpoints of the Server Middleware.
 
+- The `defaults` is the default configuration of the SDK.
+
 - The `getRequestHeaders` function is used to provide the incoming headers within your requests. You can use `getRequestHeaders` to access and proxy the initial cookie headers to SDK requests during SSR. Initial headers could be provided by the [`getSdk`](#getsdk) method.
