-| Technology  | Description         						| Link                |
-|-------------|---------------------------------|---------------------|
-| Flutter 		| Cross-platform mobile framework	| [Link][flutter]     |
-
-[flutter]: https://flutter.dev/
-
-## Features
-
-This mobile app. provides:
-
-- user authentication; and
-- transaction logging.
-
-## Installation
-
-1. Install [Flutter](https://flutter.dev/docs/get-started/install);
-1. if this is your first Flutter project, install the [Flutter SDK](https://flutter.dev/docs/get-started/test-drive);
-1. set up [your editor](https://flutter.dev/docs/get-started/editor):
-    - we recommend using [Android Studio](https://developer.android.com/studio).
-1. add the line `flutter.sdk=⟨ path to Flutter SDK ⟩` to the file `android/local.properties`.
-
-## Configuration
-
-App. configuration settings are found in `pubspec.yaml`.
-
-Build settings are found in the `android/` directory, in the `build.gradle`, `gradle.properties` and `settings.gradle` files.
-
-## Usage
-
-### Development
-
-To activate debugging, add the following import statement:
-
-```dart
-import 'package:flutter/foundation.dart';
 ```
 
-After that, you can generate debugging output using `debugPrint()`.
+## Debugging
 
-### Production
+```
+// debug
+import 'package:flutter/foundation.dart';
+debugPrint('$foo');
+```
 
-Run `flutter build apk -t lib/main_dev.dart` to generate an APK file.
+## Further Reading
 
-## Testing
+A few resources to get you started if this is your first Flutter project:
 
-TODO
+- [Lab: Write your first Flutter app](https://flutter.io/docs/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://flutter.io/docs/cookbook)
 
-## Code Formatting
