+
+> Reduce transform functions with PostCSS.
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-reduce-transforms) do:
+
+```
+npm install postcss-reduce-transforms --save
+```
+
+## Example
+
+This module will reduce transform functions where possible. For more examples,
+see the [tests](src/__tests__/index.js).
+
+### Input
+
+```css
+h1 {
+  transform: rotate3d(0, 0, 1, 20deg);
+}
+```
+
+### Output
+
+```css
+h1 {
+  transform: rotate(20deg);
+}
+```
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
