+# Navigation and Routing
+A sample that shows how to use [go_router](https://pub.dev/packages/go_router)
+API to handle common navigation scenarios.
+
+## Goals
+- Demonstrate common navigation scenarios:
+  - Parsing path parameters (`/user/:id`)
+  - Sign in (redirection)
+  - Nested navigation using ShellRoute
+- Demonstrate how [deep linking](https://docs.flutter.dev/ui/navigation/deep-linking#get-started) is configured on iOS and Android
+- Demonstrate how to use the Link widget from `package:url_Launcher` with the
+  Router API.
