 ## Geliştirme Akışı — Otomatik Build ve Kurulum
 
+### Linux
+1. Debug build: `flutter build linux --debug`
+2. Sisteme kurulum: `./install.sh` (debug bundle tercih edilir → `~/.local/lib/imajviewer/`)
+
+### Windows
+1. Ortam kurulumu: [windows-setup.md](windows-setup.md) rehberini takip edin
+2. Build + installer: `.\build-windows.ps1`
+3. Manuel kurulum (build çıktılarından): `.\install.ps1`
+4. Kaldırma: `.\uninstall.ps1`
+
 Projede değişiklik yapıldıktan sonra otomatik yapılır (ayrıca istenmez):
 1. Debug build: `flutter build linux --debug`
 2. Sisteme kurulum: `./install.sh` (debug bundle tercih edilir → `~/.local/lib/imajviewer/`)

+# Windows Development Ortam Kurulum Rehberi
+
+Bu doküman, ImajViewer Flutter projesini Windows üzerinde geliştirmek için gerekli ortamın sıfırdan kurulmasını adım adım anlatır.
+
+## Gereksinimler
+
+| Araç | Minimum Versiyon | Açıklama |
+|------|-----------------|----------|
+| Flutter SDK | 3.27+ (stable) | UI framework |
+| Visual Studio 2022 | Build Tools veya Community | C++ derleyici (MSVC) |
+| CMake | 3.14+ | Build sistemi |
+| Inno Setup | 6.x | Windows installer (.exe) oluşturma |
+
+## Adım 1: Flutter SDK Kurulumu
+
+### Yöntem A: Resmi kurulum (Önerilen)
+
+1. [Flutter SDK'yı indirin](https://docs.flutter.dev/get-started/install/windows)
+2. ZIP'i `C:\src\flutter` dizinine çıkarın
+3. PATH'e ekleyin:
+
+```powershell
+# PowerShell (Admin)
+[Environment]::SetEnvironmentVariable(
+  "PATH",
+  "$([Environment]::GetEnvironmentVariable("PATH", "Machine"))\;C:\src\flutter\bin",
+  "Machine"
+)
+```
+
+4. Yeni terminalde doğrulayın:
+
+```powershell
+flutter doctor
+```
+
+### Yöntem B: Winget ile kurulum
+
+```powershell
+winget install --id OpenFlutter.FlutterSDK
+```
+
+### Flutter doctor kontrolleri
+
+```powershell
+flutter doctor
+```
+
+Çıktıda `[✗]` işaretli bileşenler için önerilen adımları uygulayın. En azından şunlar `✓` olmalı:
+
+- Flutter
+- Android toolchain (opsiyonel, sadece mobile geliştirme için)
+- Visual Studio (eğer kuruluysa)
+- Connected device (Windows)
+
+## Adım 2: Visual Studio 2022 Build Tools Kurulumu
+
+Flutter Windows build'i için MSVC C++ derleyicisi gerekir.
+
+### Seçenek A: Visual Studio Build Tools (Sadece build araçları)
+
+1. [Visual Studio Build Tools 2022](https://visualstudio.microsoft.com/visual-cpp-build-tools/) indirin
+2. Kurulum sihirbazında **"Desktop development with C++"** workload'unu işaretleyin
+3. Aşağıdaki bileşenler otomatik seçilecektir:
+   - MSVC v143 - VS 2022 C++ x64/x86 build tools
+   - Windows 10/11 SDK
+   - CMake tools (opsiyonel ama önerilir)
+
+### Seçenek B: Visual Studio Community (Tam IDE)
+
+1. [Visual Studio Community 2022](https://visualstudio.microsoft.com/vs/community/) indirin
+2. Kurulumda **"Desktop development with C++"** workload'unu seçin
+
+### Doğrulama
+
+```powershell
+cl
+```
+
+Çıktıda `Microsoft (R) C/C++ Optimizing Compiler` görünmelidir.
+
+## Adım 3: CMake Kurulumu
+
+Visual Studio Build Tools ile birlikte gelir ancak bağımsız kurulum da yapılabilir.
+
+### Winget ile:
+
+```powershell
+winget install --id Kitware.CMake
+```
+
+### Doğrulama:
+
+```powershell
+cmake --version
+```
+
+## Adım 4: Inno Setup 6 Kurulumu
+
+Windows installer (.exe) oluşturmak için gereklidir.
+
+1. [Inno Setup 6](http://www.jrsoftware.org/isdl.php#stable) indirin (`is.exe`)
+2. Kurulumu tamamlayın (varsayılan: `C:\Program Files (x86)\Inno Setup 6`)
+
+### Doğrulama:
+
+```powershell
+Test-Path "C:\Program Files (x86)\Inno Setup 6\ISCC.exe"
+```
+
+## Adım 5: Projeyi Hazırlama
+
+```powershell
+cd C:\projects\imajviewer
+
+# Bağımlılıkları indir
+flutter pub get
+
+# Analiz et
+flutter analyze
+
+# Test çalıştır
+flutter test
+```
+
+## Adım 6: Windows Build
+
+### Debug build:
+
+```powershell
+flutter build windows --debug
+```
+
+Çıktı: `build\windows\x64\runner\Debug\`
+
+### Release build:
+
+```powershell
+flutter build windows --release
+```
+
+Çıktı: `build\windows\x64\runner\Release\`
+
+## Adım 7: Installer Oluşturma (Inno Setup)
+
+```powershell
+# Release build yapıldıktan sonra
+& "C:\Program Files (x86)\Inno Setup 6\ISCC.exe" windows\installer.iss
+```
+
+Çıktı: `dist\imajviewer_setup_1.1.0.exe`
+
+## Tek Komutla Her Şey
+
+Tüm build + installer pipeline'ını tek komutla çalıştırın:
+
+```powershell
+.\build-windows.ps1
+```
+
+Bu script:
+1. `flutter pub get`
+2. `flutter build windows --release`
+3. Inno Setup ile `.exe` installer oluşturur
+
+## Sorun Giderme
+
+### "Unable to find Visual Studio installation" hatası
+
+```powershell
+flutter config --enable-windows-desktop
+```
+
+Visual Studio 2022'nin doğru kurulduğunu `flutter doctor` ile kontrol edin.
+
+### CMake hataları
+
+CMake'in PATH'te olduğundan emin olun:
+
+```powershell
+$env:PATH += ";C:\Program Files\CMake\bin"
+cmake --version
+```
+
+### Inno Setup bulunamadı
+
+`build-windows.ps1` script'i otomatik arar. Manuel çalıştırmak için:
+
+```powershell
+& "C:\Program Files (x86)\Inno Setup 6\ISCC.exe" windows\installer.iss
+```
+
+### Flutter doctor'da Android SDK uyarısı
+
+Sadece desktop geliştirme yapıyorsanız bu uyarıları görmezden gelebilirsiniz.
+
+## Kurulum Sonrası
+
+Ortam hazır olduğunda:
+
+```powershell
+# Build + installer
+.\build-windows.ps1
+
+# Manuel kurulum (build çıktılarından)
+.\install.ps1
+
+# Uninstall
+.\uninstall.ps1
+```
+
+## Sistem Gereksinimleri (Minimum)
+
+- Windows 10 (1809) veya üzeri
+- 4 GB RAM (8 GB önerilir)
+- ~4 GB disk alanı (Flutter SDK + VS Build Tools + proje)
+- x64 mimari
