+
+This plugin can be used to quickly simulate nested style objects such as pseudo classes, media queries or attribute selectors.
+
+## Installation
+```sh
+yarn add fela-plugin-simulate
+```
+You may alternatively use `npm i --save fela-plugin-simulate`.
+
+
+## Usage
+Make sure to read the documentation on [how to use plugins](http://fela.js.org/docs/advanced/Plugins.html).
+
+```javascript
+import { createRenderer } from 'fela'
+import simulate from 'fela-plugin-simulate'
+
+const renderer = createRenderer({
+  plugins: [ simulate() ]
+})
+```
+
+## Example
+
+#### Input
+```javascript
+{
+  color: 'red',
+
+  '@media (min-height: 320px)': {
+    color: 'green',
+    backgroundColor: 'red'
+  },
+  ':hover': {
+    color: 'blue'
+  },
+  ':active': {
+    color: 'yellow'
+  }
+}
+```
+
+rendered with the following props
+```javascript
+{
+  simulate: {
+    ':hover': true,
+    ':active': false,
+    '@media (min-height: 320px)': true
+  }
+}
+```
+
+#### Output
+```javascript
+{
+  backgroundColor: 'red',
+  color: 'blue'
+}
+```
