+# [postcss][postcss]-normalize-url
+
+> [Normalize URLs](https://github.com/sindresorhus/normalize-url) with PostCSS.
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-normalize-url) do:
+
+```
+npm install postcss-normalize-url --save
+```
+
+## Example
+
+### Input
+
+```css
+h1 {
+    background: url("http://site.com:80/image.jpg")
+}
+```
+
+### Output
+
+```css
+h1 {
+    background: url(http://site.com/image.jpg)
+}
+```
+
+Note that this module will also try to normalize relative URLs, and is capable
+of stripping unnecessary quotes. For more examples, see the [tests](test.js).
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
+
+## API
+
+### normalize([options])
+
+Please see the [normalize-url documentation][docs]. By default,
+`normalizeProtocol`, `stripHash` & `stripWWW` are set to `false`.
