 ng add ngx-tailwind --tailwindVersion 1.9.6 --ngxBuildPlusVersion 10.1.1 --postcssVersion 7.0.35 --postcssImportVersion 12.0.1 --postcssLoaderVersion 4.0.4 --postcssScssVersion 3.0.4
 ```
 
+By default, `cross-env` is added to the `build:prod` script to be able to set `NODE_ENV=prod` cross-platform.
+If you want to override the default behavior, you can set the flag `--installCrossPlatform` to `false`:
+
+```bash
+ng add ngx-tailwind --installCrossPlatform false
+```
