-# Wine + .NET SDK Docker Image
-
-Ez a Docker image telepíti a Wine 64-bit verzióját és a Microsoft .NET SDK 9.0.301-et Windows-on keresztül.
-
-## Tartalom
-
-- Ubuntu 22.04 alapú image
-- Wine 64-bit (stable verzió)
-- .NET SDK 9.0.301 (Windows x64)
-
-## Build
-
-### Bash-sel (Git Bash, WSL, Linux, macOS):
-```bash
-chmod +x build.sh
-./build.sh
-```
-
-### Manuálisan:
-```bash
-docker build -t wine-dotnet:latest .
-```
-
-## Használat
-
-### Alapvető futtatás:
-```bash
-docker run -it --rm wine-dotnet:latest
-```
-
-### Projektekkel való munka (volume mounting):
-```bash
-docker run -it --rm -v $(pwd)/projects:/home/wineuser/projects wine-dotnet:latest
-```
-
-Windows PowerShell-ben:
-```powershell
-docker run -it --rm -v ${PWD}/projects:/home/wineuser/projects wine-dotnet:latest
-```
-
-## .NET használata a containerben
-
-A containerben belül használhatod a .NET SDK-t a speciális script segítségével:
-
-```bash
-# .NET verzió ellenőrzése
-./run-dotnet.sh --version
-
-# Új projekt létrehozása
-./run-dotnet.sh new console -n MyApp
-
-# Projekt build-elése
-cd MyApp
-../run-dotnet.sh build
-
-# Projekt futtatása
-../run-dotnet.sh run
-```
-
-Alternatívaként közvetlenül is használhatod:
-```bash
-# Virtual display indítása
-Xvfb :99 -screen 0 1024x768x16 &
-export DISPLAY=:99
-
-# .NET parancsok
-wine dotnet --version
-```
-
-## Megjegyzések
-
-- A container egy `wineuser` felhasználóval fut (nem root)
-- A Wine prefix előre konfigurálva van 64-bit módban
-- A .NET SDK csendben telepítve van virtual display segítségével
-- A projektek a `/home/wineuser/projects` könyvtárban tárolhatók
-- A `run-dotnet.sh` script automatikusan kezeli a virtual display-t
