+### Cross-Platform Building (Linux to Windows)
+
+If you are on Linux and want to build the Windows `.exe` and installer locally, you can use **Wine**.
+
+1. **Install Windows Python and Git inside Wine**:
+    ```bash
+    # Download Python installer
+    wget https://www.python.org/ftp/python/3.13.1/python-3.13.1-amd64.exe
+    # Install Python to a specific path
+    wine python-3.13.1-amd64.exe /quiet InstallAllUsers=1 TargetDir=C:\Python313 PrependPath=1
+
+    # Download Git installer
+    wget https://github.com/git-for-windows/git/releases/download/v2.52.0.windows.1/Git-2.52.0-64-bit.exe
+    # Install Git (quietly)
+    wine Git-2.52.0-64-bit.exe /VERYSILENT /NORESTART
+    ```
+
+2. **Install Build Dependencies in Wine**:
+    ```bash
+    wine C:/Python313/python.exe -m pip install cx_Freeze poetry
+    wine C:/Python313/python.exe -m pip install -r requirements.txt
+    ```
+
+3. **Run the Build Task**:
+    ```bash
+    # Build only the Windows portable exe
+    WINE_PYTHON="wine C:/Python313/python.exe" task build-exe-wine
+
+    # Or build everything (Linux + Windows) at once
+    WINE_PYTHON="wine C:/Python313/python.exe" task build-electron-all-wine
+    ```
+
