+# Fuel Stats
+
+Fuel Stats is a Flutter application for tracking vehicle fuel consumption and service history. It lets you record refuels and maintenance, manage multiple vehicles, and visualise trends in cost and efficiency.
+
+## Features
+- Email-based authentication with login and sign-up flows
+- Manage vehicles and choose a default one
+- Log refuels with liters, price, mileage and notes
+- Record maintenance/service events, including cost and optional photos
+- Stats dashboard with consumption figures and kilometers driven
+- Charts for gas price and fuel consumption trends
+
+## Platform Support
+The app is tested only on Android. A web build should also work, but iOS, macOS, Windows, and Linux have not been tested.
+
+## Configuration
+The app communicates with a Node.js backend maintained in a separate project: [Fuel Stats Server](https://github.com/filiprojek/fuelstats-server).
+Provide the server's base URL at build time using a compile-time define:
+
+```bash
+flutter run --dart-define=API_BASE_URL=https://api.example.com
+```
+
+## Getting Started
+1. Install [Flutter](https://flutter.dev) (3.7 or later).
+2. Fetch dependencies:
+   ```bash
+   flutter pub get
+   ```
+3. Launch the application:
+   ```bash
+   flutter run --dart-define=API_BASE_URL=http://localhost:6060
+   ```
+
+## CI/CD
+A GitHub Actions workflow builds a profile APK on each push to the `dev` branch. The workflow reads the version from `pubspec.yaml`, uses the repository commit count as the build number, and uploads the APK as an artifact.

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
