    If your Next.js project is not at the root directory where you are running the commands, for example if you are using a monorepo, you can specify the location of the next.config.js as an argument to the script:
 
    ```json
-   "export": "next build && next export && next-image-export-optimizer --nextConfigPath path/to/my/next.config.js"
+   "export": "next build && next-image-export-optimizer --nextConfigPath path/to/my/next.config.js"
    ```
 
    If you want to specify the path to the output folder, you can either do so by setting the `nextImageExportOptimizer_exportFolderPath` environment variable in your **next.config.js** file or by passing the `--exportFolderPath` argument to the script:
 
    ```json
-    "export": "next build && next export && next-image-export-optimizer --exportFolderPath path/to/my/export/folder"
+    "export": "next build && next-image-export-optimizer --exportFolderPath path/to/my/export/folder"
    ```
 
 4. Change the **\<Image />** component to the **\<ExportedImage />** component of this library.
