 ## Usage
 
-Because of the complexity of this config, it is exported as a factory function that takes an options object and returns an ESLint configuration object.
+Because of the complexity of the configurations, this package exports several utilities:
 
-This package exports 2 utility functions:
-
-- `defineConfig`, as a re-export of the [`config` function from `typescript-eslint`](https://typescript-eslint.io/packages/typescript-eslint#config).
-- `createConfig`, used for creating an ESLint configuration array that extends from the [`typescript-eslint` shared configs](https://typescript-eslint.io/users/configs).
+- `defineConfigWithVueTs`, a utility function whose type signature is the same as the [`config` function from `typescript-eslint`](https://typescript-eslint.io/packages/typescript-eslint#config), but will modify the given ESLint config to work with Vue.js + TypeScript.
+- `vueTsConfigs`, contains all the [shared configruations from `typescript-eslint`](https://typescript-eslint.io/users/configs) (in camelCase, e.g. `vueTsConfigs.recommendedTypeChecked`), and applies to `.vue` files in addition to TypeScript files.
+- a Vue-specific config factory: `configureVueProject({ scriptLangs, rootDir })`. More info below.
 
 ### Minimal Setup
 
 ```js
 // eslint.config.mjs
 import pluginVue from 'eslint-plugin-vue'
 import {
-  defineConfig,
-  createConfig as vueTsEslintConfig,
+  defineConfigWithVueTs,
+  vueTsConfigs,
 } from '@vue/eslint-config-typescript'
 
-export default defineConfig(
+export default defineConfigWithVueTs(
   pluginVue.configs['flat/essential'],
-  vueTsEslintConfig(),
+  vueTsConfigs.recommended,
 )
 ```
 
 The above configuration enables [the essential rules for Vue 3](https://eslint.vuejs.org/rules/#priority-a-essential-error-prevention) and [the recommended rules for TypeScript](https://typescript-eslint.io/rules/?=recommended).
 
-All the `<script>` blocks in `.vue` files _MUST_ be written in TypeScript (should be either `<script setup lang="ts">` or `<script lang="ts">`).

 Instead, you can start by extending from the `recommendedTypeChecked` configuration and then turn on/off the rules you need.

+## Use As a Normal Shared ESLint Config (Not Recommended)
+
+You can use this package as a normal ESLint config, without the `defineConfigWithVueTs` helper. But in this case, overriding the rules for `.vue` files would be more difficult and comes with many nuances. Please be cautious.
+
+You can check [the documentation for 14.1 and earlier versions](https://github.com/vuejs/eslint-config-typescript/tree/v14.1.4#usage) for more information.

+
+## Recommended IDE Setup
+
+[VSCode](https://code.visualstudio.com/) + [Volar](https://marketplace.visualstudio.com/items?itemName=Vue.volar) (and disable Vetur).
+
+## Type Support for `.vue` Imports in TS
+
+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 [Volar](https://marketplace.visualstudio.com/items?itemName=Vue.volar) to make the TypeScript language service aware of `.vue` types.
+
+## Customize configuration
+
+See [Vite Configuration Reference](https://vite.dev/config/).
+
+## Project Setup
+
+```sh
+npm install
+```
+
+### Compile and Hot-Reload for Development
+
+```sh
+npm run dev
+```
+
+### Type-Check, Compile and Minify for Production
+
+```sh
+npm run build
+```
+
+### Run Unit Tests with [Vitest](https://vitest.dev/)
+
+```sh
+npm run test:unit
+```
+
+### Run End-to-End Tests with [Cypress](https://www.cypress.io/)
+
+```sh
+npm run test:e2e:dev
+```
+
+This runs the end-to-end tests against the Vite development server.
+It is much faster than the production build.
+
+But it's still recommended to test the production build with `test:e2e` before deploying (e.g. in CI environments):
+
+```sh
+npm run build
+npm run test:e2e
+```
+
+### Lint with [ESLint](https://eslint.org/)
+
+```sh
+npm run lint
+```
