 The native app serves `ui/dist` when it exists, otherwise it falls back to the source UI directory during development.
 
+## Package
+
+Build the UI, build the native Release target, then install into a portable runtime folder:
+
+```powershell
+cd ui
+npm ci
+npm run build
+cd ..
+cmake --preset vs2022-x64-release
+cmake --build --preset build-release
+cmake --install build/vs2022-x64-release --config Release --prefix dist/VideoShader
+```
+
+The package folder will contain:
+
+```text
+dist/VideoShader/
+  LoopThroughWithOpenGLCompositing.exe
+  dvp.dll
+  config/
+  shaders/
+  ui/dist/
+  runtime/templates/
+```
+
+You can run `LoopThroughWithOpenGLCompositing.exe` directly from that folder. In packaged mode, the app resolves `config/`, `shaders/`, `ui/dist/`, and `runtime/templates/` relative to the exe folder. In development mode, it still falls back to repo-root discovery.
+
+Create a zip for distribution:
+
+```powershell
+Compress-Archive -Path dist/VideoShader/* -DestinationPath dist/VideoShader.zip -Force
+```
+
