### Remarks

Use the `PatchPackage` option in your build script to rebuild and deploy project changes. Patching an existing deployment can be significantly faster than rebuilding the entire application. Only [BuildOptions.Development](/engine/6000.6/script-reference/unityeditor/buildoptions/development.md) builds can be patched.

To patch a package, build the project using the following options in your build script: `BuildOptions.PatchPackage` or [BuildOptions.Development](/engine/6000.6/script-reference/unityeditor/buildoptions/development.md). Alternatively, you can click the **Patch** or **Patch And Run** buttons on the **Build Settings** window.

This option will implicitly change some options to enhance performance of deployment. The application will not be split using expansion files (such as OBB).
