+## Type Support for `.vue` Imports in TS
 
-Ensure you have the correct node/npm version
+TypeScript cannot handle type information for `.vue` imports by default, so we replace the `tsc` CLI with `vue-tsc` for type checking. In editors, we need [TypeScript Vue Plugin (Volar)](https://marketplace.visualstudio.com/items?itemName=Vue.vscode-typescript-vue-plugin) to make the TypeScript language service aware of `.vue` types.
+
+If the standalone TypeScript plugin doesn't feel fast enough to you, Volar has also implemented a [Take Over Mode](https://github.com/johnsoncodehk/volar/discussions/471#discussioncomment-1361669) that is more performant. You can enable it by the following steps:
+
+1. Disable the built-in TypeScript Extension
+   1. Run `Extensions: Show Built-in Extensions` from VSCode's command palette
+   2. Find `TypeScript and JavaScript Language Features`, right click and select `Disable (Workspace)`
+2. Reload the VSCode window by running `Developer: Reload Window` from the command palette.
