+# Primer Stylelint Config
+
+[![NPM version](http://img.shields.io/npm/v/stylelint-config-primer.svg)](https://www.npmjs.org/package/stylelint-config-primer)
+[![Build Status](https://travis-ci.org/primer/stylelint-config-primer.svg?branch=master)](https://travis-ci.org/primer/stylelint-config-primer)
+
+> A sharable stylelint config object that enforces GitHub's css rules
+
+## Install
+
+```
+$ npm install --save stylelint-config-primer
+```
+
+## Usage
+
+Within your [stylelint config object](http://stylelint.io/user-guide/configuration/#extends) You can extend this configuration. This will serve as a base for your config, then you can make overrides in your own config object.
+
+```json
+{
+  "extends": "stylelint-config-primer"
+}
+```
