+## Desktop Integration
+
+### Adding "Open with Sago Multi Scrambler Puzzle II" to Context Menu
+
+#### Linux (GNOME/Nautilus, KDE/Dolphin, etc.)
+
+1. **Create a desktop entry file:**
+   
+   Create the file `~/.local/share/applications/sago-multi-scrambler-puzzle2.desktop`:
+   
+   ```ini
+   [Desktop Entry]
+   Version=1.0
+   Type=Application
+   Name=Sago Multi Scrambler Puzzle II
+   Comment=Image scrambling puzzle game
+   Exec=/full/path/to/sago_multi_scrambler_puzzle2 %f
+   Icon=/full/path/to/icon.png
+   Terminal=false
+   Categories=Game;LogicGame;
+   MimeType=image/jpeg;image/png;image/jpg;
+   ```
+
+   Replace `/full/path/to/sago_multi_scrambler_puzzle2` with the actual path to the executable.
+
+2. **Update the desktop database:**
+   
+   ```bash
+   update-desktop-database ~/.local/share/applications/
+   ```
+
+After this, right-clicking on an image file should show "Open With → Sago Multi Scrambler Puzzle II" in the context menu.
+
+#### Windows
+
+1. **Create a registry file** `sago-context-menu.reg`:
+   
+   ```reg
+   Windows Registry Editor Version 5.00
+
+   [HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\SagoMultiScramblerPuzzle]
+   @="Open with Sago Multi Scrambler Puzzle II"
+   "Icon"="C:\\path\\to\\sago_multi_scrambler_puzzle2.exe"
+
+   [HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\SagoMultiScramblerPuzzle\command]
+   @="\"C:\\path\\to\\sago_multi_scrambler_puzzle2.exe\" \"%1\""
+   ```
+
+   Replace `C:\\path\\to\\` with the actual path to the executable.
+
+2. **Import the registry file:**
+   
+   Double-click the `.reg` file and confirm the import.
+
+3. **To remove later** (create `sago-context-menu-remove.reg`):
+   
+   ```reg
+   Windows Registry Editor Version 5.00
+
+   [-HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\SagoMultiScramblerPuzzle]
+   ```
+
+After this, right-clicking on an image file will show "Open with Sago Multi Scrambler Puzzle II" in the context menu.
