-# mileograph_flutter
+# Mileograph (Flutter)
 
-A new Flutter project.
+Mileograph is a Flutter client for logging and analysing railway journeys. It lets you record legs, group them into trips, track locomotive mileage, and view stats and leaderboards.
 
-## Getting Started
+## Features
+- Add and edit journey legs with traction, timings, routes, notes, and delays.
+- Group legs into trips and see mileage totals and traction stats.
+- Browse traction, view loco details, mileage leaderboards, timelines, and legs.
+- Dashboard with homepage stats, “On This Day”, recent traction changes, and trips.
+- Profile badges, class clearance progress, and traction progress.
+- Offline-friendly UI built with Provider, GoRouter, and Material 3 styling.
 
-This project is a starting point for a Flutter application.
+## Project layout
+- `lib/objects/objects.dart` — shared model classes and helpers.
+- `lib/services/` — API, data loading, auth, endpoints, distance units.
+- `lib/components/` — UI pages and widgets (entries, traction, dashboard, trips, settings, etc.).
+- `assets/` — icons/fonts and other bundled assets.
 
-A few resources to get you started if this is your first Flutter project:
+## Prerequisites
+- Flutter SDK (3.x or later recommended).
+- Dart SDK (bundled with Flutter).
+- A Mileograph API endpoint (set in Settings within the app).
 
-- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+## Setup
-- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+1) Install Flutter: follow https://docs.flutter.dev/get-started/install and ensure `flutter doctor` is green.  
+2) Get dependencies:  
+   ```bash
+   flutter pub get
+   ```
+3) Configure an API endpoint:
+   - Run the app, open Settings, and set the base URL for your Mileograph backend.
+   - The app probes the endpoint for a version string before saving.
 
-For help getting started with Flutter development, view the
+## Running
-[online documentation](https://docs.flutter.dev/), which offers tutorials,
+- Debug (mobile/web depending on your toolchain):  
-samples, guidance on mobile development, and a full API reference.
+  ```bash
+  flutter run
+  ```
+- Release build (example for Android):  
+  ```bash
+  flutter build apk --release
+  ```
+
+## Testing and linting
+- Static analysis: `flutter analyze`
+- Unit/widget tests (if present): `flutter test`
+
+## Contributing
+1) Fork or branch from `main`.  
+2) Make changes with clear, small commits.  
+3) Add tests where feasible and keep `flutter analyze` clean.  
+4) Submit a PR describing:
+   - What changed and why.
+   - How to test or reproduce.
+   - Any API or migration notes.
+
+### Coding conventions
+- Prefer stateless widgets where possible; keep state localized.
+- Use existing services in `lib/services` for API access; add new endpoints there.
+- Keep models in `objects.dart` (or nearby files) and use helper parsers for defensive JSON handling.
+- Follow Material theming already in use; keep strings user-facing and concise.
+
+### Issue reporting
+Include device/OS, Flutter version (`flutter --version`), steps to reproduce, expected vs. actual behaviour, and logs if available.
+
