+# OpenHaystack Mobile
+Seemoo Lab WS21/22 project: Porting OpenHaystack to Mobile
+
+# About OpenHaystack
+OpenHaystack is a project that allows location tracking of Bluetooth Low Energy (BLE) devices over Apples Find My Network.
+
+See the [OpenHaystack GitHub page](https://github.com/seemoo-lab/openhaystack/) for more deatils on how it works.
+
+# Development
+This project is written in [Dart](https://dart.dev/), using the cross platform development framework [Flutter](https://flutter.dev/). This allows the creation of apps for all major platforms using a single code base.
+
+## Requisites
+To develop and build the project the following tools are needed and should be installed.
+
+- [Flutter SDK](https://docs.flutter.dev/get-started/install)
+- [Xcode](https://developer.apple.com/xcode/) (for iOS)
+- [Android SDK / Studio](https://developer.android.com/studio/) (for Android)
+- (optional) IDE Plugin (e.g. for [VS Code](https://marketplace.visualstudio.com/items?itemName=Dart-Code.flutter))
+
+To check the installation run `flutter doctor`. Before continuing review all displayed errors.
+
+
+## Getting Started
+First the necessary dependencies need to be installed. The IDE plugin may take care of this automatically.
+```bash
+$ flutter pub get
+```
+
+Then set the location proxy server URL in [reports_fetcher.dart](lib/findMy/reports_fetcher.dart) (replace `https://add-your-proxy-server-here/getLocationReports` with your custom URL).
+
+To run the debug version of the app start a supported emulator and run
+```bash
+$ flutter run
+```
+
+When the app is running a new key pair can be created / imported in the app.
+
+## Project Structure
+The project follows the default structure for flutter applications. The `android`, `ios` and `web` folders contain native projects for the specified platform. Native code can be added here for example to access special APIs.
+
+The business logic and UI can be found in the `lib` folder. This folder is furthermore separated into modules containing code regarding a common aspect.
+The business logic for accessing and decrypting the location reports is separated in the `findMy` folder for easier reuse.
+
+## Building
+This project currently supports iOS and Android targets.
+If you are building the project for the first time, you need to run
+```bash
+$ flutter pub run flutter_launcher_icons:main 
+```
+to create the icons and then, to create a distributable application package run
+```bash
+$ flutter build [ios|apk|web]
+```
+The resulting build artifacts can be found in the `build` folder. To deploy the artifacts to a device consult the platform specific documentation.
