+# postcss-minify-font-values [![Build Status][ci-img]][ci]
+
+> Minify font declarations with PostCSS.
+
+This module will try to minimise the `font-family`, `font-weight` and `font` shorthand
+properties; it can unquote font families where necessary, detect & remove
+duplicates, and cut short a declaration after it finds a keyword. For more
+examples, see the [tests](test).
+
+```css
+h1 {
+  font:bold 2.2rem/.9 "Open Sans Condensed", sans-serif;
+}
+
+p {
+  font-family: "Helvetica Neue", Arial, sans-serif, Helvetica;
+  font-weight: normal;
+}
+```
+
+```css
+h1 {
+  font:700 2.2rem/.9 Open Sans Condensed,sans-serif
+}
+
+p {
+  font-family: Helvetica Neue,Arial,sans-serif;
+  font-weight: 400;
+}
+```
+
+## API
+
+### minifyFontValues([options])
+
+#### options
+
+##### removeAfterKeyword
+
+Type: `boolean`
+Default: `false`
+
+Pass `true` to remove font families after the module encounters a font keyword,
+for example `sans-serif`.
+
+##### removeDuplicates
+
+Type: `boolean`
+Default: `true`
+
+Pass `false` to disable the module from removing duplicated font families.
+
+##### removeQuotes
+
+Type: `boolean`
+Default: `true`
+
+Pass `false` to disable the module from removing quotes from font families.
+Note that oftentimes, this is a *safe optimisation* & is done safely. For more
+details, see [Mathias Bynens' article][mathias].
+
+## Usage
+
+```js
+postcss([ require('postcss-minify-font-values') ])
+```
+
+See [PostCSS] docs for examples for your environment.
