-# LocalSpend Mobile App.
+# LocalSpend (Mobile App.)
 
-This repo. contains the mobile application for use with the LocalSpend system, 
-using Flutter.
+Looking to discover if the value of spending local can be measured, understood and shown.
 
-## Getting Started
+This repository contains the mobile application for the LocalSpend system. See also:
 
-Follow these steps to get the project up-and-running:
+* the [Web application](https://github.com/Pear-Trading/Foodloop-Web); and
+* the [server](https://github.com/Pear-Trading/Foodloop-Server).
 
-1. Install [Flutter](https://flutter.dev/docs/get-started/install)
-1. Set up [your editor](https://flutter.dev/docs/get-started/editor)
-    1. If this is your first Flutter project, install the [Flutter SDK](https://flutter.dev/docs/get-started/test-drive)
-1. Add the line `flutter.sdk=⟨ path to Flutter SDK ⟩` to the file `androud/local.properties`

-To build an apk from dev, use:
-```
-flutter build apk -t lib/main_dev.dart
-```
+## Technology Stack
 
-## Debugging
+The mobile app. is written in [Dart](https://dart.dev/).

+| 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';
-debugPrint('$foo');
 ```
 
-## Further Reading
+After that, you can generate debugging output using `debugPrint()`.
 
-A few resources to get you started if this is your first Flutter project:
+### Production
 
-- [Lab: Write your first Flutter app](https://flutter.io/docs/get-started/codelab)
-- [Cookbook: Useful Flutter samples](https://flutter.io/docs/cookbook)
+Run `flutter build apk -t lib/main_dev.dart` to generate an APK file.
 
-For help getting started with Flutter, view our 
-[online documentation](https://flutter.io/docs), which offers tutorials, 
-samples, guidance on mobile development, and a full API reference.
+## Testing
