+Some users prefer to download an extension once from the Marketplace and then install it to multiple VS Code instances from a local share. This is useful when there are connectivity concerns or if your development team wants to use a fixed set of extensions.
 
-To download an extension, navigate to the details page for the specific extension within the [Marketplace](https://marketplace.visualstudio.com/vscode). On that page, there is a **Download Extension** link in the **Resources** section, which is located on the right-hand side of the page.
+To download an extension, use the following command option:
+```
+code --download-extension <UniqueExtensionID> --location <Path>
+
+Example:
+code --download-extension ms-python.python --location ~/vscode/testing
+```
+You can copy the extension ID from the extension details page ![Copy Extension ID](./images/extension-marketplace/copy-extension-id.png).
 
 Once downloaded, you can then install the extension via the **Install from VSIX** command in the Extensions view command dropdown.
