+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+BackSafe is a cross-platform desktop application for backing up data from mobile phones (primarily Android, with photos/videos support on iOS/iPadOS) using a user-provided API key. Built with Avalonia UI and .NET 8, targeting Windows, macOS, and Linux.
+
+## Development Commands
+
+### Build and Run
+```bash
+dotnet build                    # Build the project
+dotnet run                      # Run the application
+dotnet build -c Release         # Build for release
+```
+
+### Debugging
+- Avalonia diagnostics are enabled in Debug builds only (BackSafe.csproj:22-25)
+- Use F12 or Ctrl+F12 within the running application to access DevTools in Debug mode
+
+## Architecture
+
+### UI Framework: Avalonia UI
+- Uses AXAML (Avalonia XAML) for UI definitions
+- Fluent theme is the default (App.axaml:13)
+- Compiled bindings enabled by default (BackSafe.csproj:8)
+
+### MVVM Pattern
+- **ViewModels**: Inherit from `ViewModelBase` (extends `ObservableObject` from CommunityToolkit.Mvvm)
+- **Views**: Located in `Views/` directory, defined with `.axaml` files and code-behind `.axaml.cs`
+- **ViewLocator**: Automatically maps ViewModels to Views by naming convention (ViewModel → View)
+  - Example: `MainWindowViewModel` → `MainWindow`
+  - Implementation in ViewLocator.cs:16
+
+### Application Entry Point
+- `Program.cs`: Standard .NET entry point
+  - Configures Avalonia with platform detection, Inter font, and trace logging
+- `App.axaml.cs`: Avalonia initialization
+  - Disables Avalonia's DataAnnotation validation to avoid conflicts with CommunityToolkit (App.axaml.cs:35-46)
+  - Sets MainWindow with MainWindowViewModel as DataContext
+
+### Key Dependencies
+- **Avalonia 11.3.6**: Cross-platform UI framework
+- **CommunityToolkit.Mvvm 8.2.1**: MVVM helpers (ObservableObject, commands, etc.)
+- **Avalonia.Fonts.Inter**: Default font package
+
+### Project Structure
+- `ViewModels/`: Contains all ViewModel classes
+- `Views/`: Contains AXAML view definitions and code-behind
+- `Models/`: Placeholder directory for data models
+- `Assets/`: Application resources (icons, etc.)
+- `app.manifest`: Windows application manifest
+
+## MVVM Conventions
+- ViewModels use partial classes to support MVVM Toolkit source generators
+- Properties in ViewModels should use `[ObservableProperty]` attribute for automatic INotifyPropertyChanged implementation
+- Views use `x:DataType` for compiled bindings (see MainWindow.axaml:8)
