+# Nuxt ESLint Config
+
+[ESlint](https://eslint.org/) config used for Nuxt.js
+
+## Usage
+
+Do you want to add the config to your own projects? There you go:
+
+1. Add this package to your devDependencies (`npm i -D @nuxtjs/eslint-config` or `yarn add -D @nuxtjs/eslint-config`)
+2. Add the [`peerDependencies`](./package.json) to your project
+
+`npm i -D eslint eslint-config-standard eslint-plugin-import eslint-plugin-jest eslint-plugin-node eslint-plugin-promise eslint-plugin-standard eslint-plugin-vue`
+
+3. Create a `.eslintrc.js` file
+
+4. Extend our config (you can use just the scope name as ESLint will assume the `eslint-config` prefix):
+
+```json
+{
+  "extends": [
+    "@nuxtjs"
+  ]
+}
+```
