-If you want complete control over the service responsible for managing the state of the view and for fetching the image you could pass an object conforming to the `RemoteImageService` to the related initializer:
+Under the hood the `URLSession.shared` is used by default as the `RemoteImageURLDataPublisher` to fetch the image at the specified URL.
+You can specify a custom publisher through the`remoteImageURLDataPublisher` parameter.
+As an example that's how you could add support for low data mode to the `RemoteImage` view.

+If you want complete control over the service responsible for managing the state of the view and for fetching the image you could pass an object conforming to the `RemoteImageService` protocol to the related initializer:
 
 ```swift
+final class CustomService: RemoteImageService { ... }

 let url = URL(string: "https://images.unsplash.com/photo-1524419986249-348e8fa6ad4a?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&auto=format&fit=crop&w=1950&q=80")!

+    .resizable()
+    .aspectRatio(contentMode: .fit)
+}, loadingView: {

+})
+```
+
+In addition to that you could use the new `@StateObject` property wrapper introcuded in Swift by creating an instance of the default built-in `RemoteImageService` and using the above initializer:
+
+```swift
+@StateObject var service = DefaultRemoteImageServiceFactory.makeDefaultRemoteImageService()
+// or
+@StateObject var service = DefaultRemoteImageServiceFactory.makeDefaultRemoteImageService(remoteImageURLDataPublisher: yourRemoteImageURLDataPublisher)
