+
+```sh
+# iOS
+yarn run-ios
+
+# OR
+# Android
+yarn run-android
+```
+
+To test the scheme:
+
+- ensure the example app is installed on an iOS simulator or Android emulator
+- start the example app
+
+```sh
+yarn workspace @aws-amplify/ui-react-native-example dev
+```
+
+- in a seperate terminal window, launch the app with the URI by running:
+
+```sh
+# iOS
+npx uri-scheme open -i my-scheme://
+
+# OR
+# Android
+npx uri-scheme open -a my-scheme://
