 To configure the Dart MCP server with Copilot or any other AI agent that supports the
 [VS Code MCP API](https://code.visualstudio.com/api/extension-guides/mcp), add the following
-to your VS Code user settings:
+to your VS Code user settings (Command Palette > **Preferences: Open User Settings (JSON)**):
 ```json
 "dart.mcpServer": true
 ```
 
 By adding this setting, the Dart VS Code extension will register the Dart MCP Server
 configuration with VS Code so that you don't have to manually configure the server.
 Copilot will then automatically configure the Dart MCP server on your behalf. This is
-a global setting.
-
-Alternatively, you can click the "Add to VS Code" button below to manually configure the server
-in your VS Code user settings.
