   ```sh
   npm i dynamsoft-barcode-reader-bundle@11.2.4000 -E
-  # Compared with using CDN, you need to set up more resources.
-  npm i dynamsoft-capture-vision-std@1.4.21 -E
-  npm i dynamsoft-image-processing@2.4.31 -E
   ```
 
   The resources are located at the path `node_modules/<pkg>`, without `@<version>`. You must copy "dynamsoft-xxx" packages elsewhere and add `@<version>`. The `<version>` can be obtained from `package.json` of each package. Another thing to do is to [specify the engineResourcePaths](#2-optional-specify-the-location-of-the-engine-files) so that the SDK can correctly locate the resources.
