 You can switch from the pre-set Open VSX Registry by configuring the endpoints using the following solutions.
-These examples use the URLs for Microsoft's VS Code Marketplace, see [below](#howto-vscode-marketplace) for more information on that.
 
-With the following environment variables:
-- `VSCODE_GALLERY_SERVICE_URL='https://marketplace.visualstudio.com/_apis/public/gallery'`
-- `VSCODE_GALLERY_ITEM_URL='https://marketplace.visualstudio.com/items'`
-- `VSCODE_GALLERY_CACHE_URL='https://vscode.blob.core.windows.net/gallery/index'`
-- `VSCODE_GALLERY_CONTROL_URL=''`
+You can either use the following environment variables:
+- `VSCODE_GALLERY_SERVICE_URL`
+- `VSCODE_GALLERY_ITEM_URL`
+- `VSCODE_GALLERY_CACHE_URL`
+- `VSCODE_GALLERY_CONTROL_URL`
 
 Or by creating a custom `product.json` at the following location (replace `VSCodium` by `VSCodium - Insiders` if you use that):
 - Windows: `%APPDATA%\VSCodium` or `%USERPROFILE%\AppData\Roaming\VSCodium`
 - macOS: `~/Library/Application Support/VSCodium`

 The debugger provided with Microsoft's [C# extension](https://github.com/OmniSharp/omnisharp-vscode) as well as the (Windows) debugger provided with their [C++ extension](https://github.com/Microsoft/vscode-cpptools) are very restrictively licensed to only work with the official Visual Studio Code build.
