+css-modules-require-hook
+========================
+
+Automatically compiles a CSS Module to a low-level interchange format called ICSS or [Interoperable CSS](https://github.com/css-modules/icss).
+
+One of the ways you can compile [CSS Modules](https://github.com/css-modules/css-modules) to the ICSS format is through the require hook. The require hook will bind itself to node's require and automatically compile files on the fly. This is similar to Babel's [babel/register](https://babeljs.io/docs/usage/require/).
+
+## Install
+
+```bash
+$ npm i css-modules-require-hook
+```
+
+## Usage
+
+```javascript
+require('css-modules-require-hook');
+```
+
+## Specifying options
+
+```javascript
+require('css-modules-require-hook')({
+  // Setting this allows you to specify custom PostCSS plugins
+  // You may use functions or strings, which match to the modules with the same name
+  use: [] // may use `u` for short
+});
+```
