+# !ninja ESlint Configuration
+
+[eslint-config-notninja](https://github.com/NotNinja/eslint-config-notninja) contains standard ESLint configurations for
+!ninja packages.
+
+[![License](https://img.shields.io/npm/l/eslint-config-notninja.svg?style=flat-square)](https://github.com/NotNinja/eslint-config-notninja/blob/master/LICENSE.md)
+[![Release](https://img.shields.io/npm/v/eslint-config-notninja.svg?style=flat-square)](https://www.npmjs.com/package/eslint-config-notninja)
+
+* [Install](#install)
+* [Configuration](#configuration)
+* [Bugs](#bugs)
+* [Contributors](#contributors)
+* [License](#license)
+
+## Install
+
+Install using `npm`:
+
+``` bash
+$ npm install --save-dev eslint-config-notninja
+```
+
+You'll need to have at least [Node.js](https://nodejs.org) installed.
+
+## Configuration
+
+Create an ESLint configuration file within your package that extends this configuration:
+
+``` json
+{
+  "extends": "notninja",
+  ...
+}
+```
+
+This will import the ECMAScript 5 configuration by default. This can also be done by extending `"notninja/es5"`. For
+ECMAScript 6 packages, please extend `"notninja/es6"` instead.
+
+## Bugs
+
+If you have any problems or would like to see changes currently in development you can do so
+[here](https://github.com/NotNinja/eslint-config-notninja/issues).
