+### Packaging & Building
+
+To package and compile **Dekupai** into standalone production binaries or installers for Windows and macOS, we use the integrated `electron-builder` engine:
+
+*   **Build for Windows (NSIS Standalone Installer .exe)**:
+    ```bash
+    npm run build:win
+    ```
+    *Compiles a single-file executable setup installer inside the `dist/` directory.*
+
+*   **Build for macOS (Standalone DMG Volume .dmg)**:
+    ```bash
+    npm run build:mac
+    ```
+    *Compiles the installer package for Apple Systems inside the `dist/` directory. (Note: You can compile macOS builds on Windows using target overrides, but native signed builds are best run on a macOS host).*
+
+*   **Compile for Both Platforms Simultaneously**:
+    ```bash
+    npm run build:all
+    ```
