+
+> Selector parser with built in methods for working with selector strings.
+
+## Install
+
+With [npm](https://npmjs.com/package/postcss-selector-parser) do:
+
+```
+npm install postcss-selector-parser
+```
+
+## Quick Start
+
+```js
+const parser = require('postcss-selector-parser');
+const transform = selectors => {
+    selectors.walk(selector => {
+        // do something with the selector
+        console.log(String(selector))
+    });
+};
+
+const transformed = parser(transform).processSync('h1, h2, h3');
+```
+
+To normalize selector whitespace:
+
+```js
+const parser = require('postcss-selector-parser');
+const normalized = parser().processSync('h1, h2, h3', {lossless: false});
+// -> h1,h2,h3
+```
+
+Async support is provided through `parser.process` and will resolve a Promise
+with the resulting selector string.
