 If you find IntelliSense has stopped working, the language service may not be running. Try restarting VS Code and this should solve the issue. If you are still missing IntelliSense features after installing a language extension, open an issue in the repository of the language extension.
 
+> [!NOTE]
+> In very large workspaces, IntelliSense features may be partially disabled for
+> performance reasons. If this happens, try excluding large folders (such as
+> `node_modules` or build output directories) using the `setting(files.exclude)` or
