+
+> Critters is a plugin that inlines your app's [critical CSS] and lazy-loads the rest.
+
+## critters [![npm](https://img.shields.io/npm/v/critters-webpack-plugin.svg?style=flat)](https://www.npmjs.org/package/critters)
+
+It's a little different from [other options](#similar-libraries), because it **doesn't use a headless browser** to render content. This tradeoff allows Critters to be very **fast and lightweight**. It also means Critters inlines all CSS rules used by your document, rather than only those needed for above-the-fold content. For alternatives, see [Similar Libraries](#similar-libraries).
+
+Critters' design makes it a good fit when inlining critical CSS for prerendered/SSR'd Single Page Applications. It was developed to be an excellent compliment to [prerender-loader](https://github.com/GoogleChromeLabs/prerender-loader), combining to dramatically improve first paint time for most Single Page Applications.
+
+## Features
+
+- Fast - no browser, few dependencies
+- Integrates with Webpack [critters-webpack-plugin]
+- Supports preloading and/or inlining critical fonts
+- Prunes unused CSS keyframes and media queries
+- Removes inlined CSS rules from lazy-loaded stylesheets
+
+## Installation
+
+First, install Critters as a development dependency:
+
+```sh
+npm i -D critters
+```
+
+or
+
+```sh
+yarn add -D critters
+```
+
+## Usage
+
+```diff
++    const Critters = require('critters');
+
++    const c = new Critters({
++      // optional configuration (see below)
++    })
++    const res = c.process(html)
+```
+
+## Usage with webpack
+
+```diff
+// webpack.config.js
++const Critters = require('critters-webpack-plugin');
+
+module.exports = {
+  plugins: [
++    new Critters({
++      // optional configuration (see below)
++    })
+  ]
+}
+```
+
+That's it! The resultant html will have its critical CSS inlined and the stylesheets lazy-loaded.

+
+### Critters
+
+Create a Critters plugin instance with the given options.
+
+**Parameters**
+
+- `options` **Options** Options to control how Critters inlines CSS.
+
+**Examples**
+
+```javascript
+// webpack.config.js
+module.exports = {
+  plugins: [
+    new Critters({
+      // Outputs: <link rel="preload" onload="this.rel='stylesheet'">
+      preload: 'swap',
+
+      // Don't inline critical font-face rules, but preload the font URLs:
+      preloadFonts: true,
+    }),
+  ],
+};
+```
+
+### Critters
+
+All optional. Pass them to `new Critters({ ... })`.
+
+**Parameters**
+
+- `options`
+
+**Properties**
+
+- `external` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Inline styles from external stylesheets _(default: `true`)_
+- `inlineThreshold` **[Number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** Inline external stylesheets smaller than a given size _(default: `0`)_
+- `minimumExternalSize` **[Number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** If the non-critical external stylesheet would be below this size, just inline it _(default: `0`)_
+- `pruneSource` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Remove inlined rules from the external stylesheet _(default: `true`)_
+- `mergeStylesheets` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Merged inlined stylesheets into a
+  single \<style\> tag _(default: `true`)_
+- `additionalStylesheets` **[String[]](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** Glob for matching other stylesheets which should be used to evaluate critical CSS _(default: '')_
+- `preload` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** Which [preload strategy](#preloadstrategy) to use
+- `noscriptFallback` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Add `<noscript>` fallback to JS-based strategies
+- `inlineFonts` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Inline critical font-face rules _(default: `false`)_
+- `preloadFonts` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Preloads critical fonts _(default: `true`)_
+- `fonts` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Shorthand for setting `inlineFonts`+`preloadFonts`- Values:
+  - `true` to inline critical font-face rules and preload the fonts
+  - `false` to don't inline any font-face rules and don't preload fonts
+- `keyframes` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** Controls which keyframes rules are inlined.- Values:
+  - `"critical"`: _(default)_ inline keyframes rules used by the critical CSS
+  - `"all"` inline all keyframes rules
+  - `"none"` remove all keyframes rules
+- `compress` **[Boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)** Compress resulting critical CSS _(default: `true`)_
+- `logLevel` **[String](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)** Controls [log level](#loglevel) of the plugin _(default: `"info"`)_
+
+### LogLevel
+
+Controls log level of the plugin. Specifies the level the logger should use. A logger will
+not produce output for any log level beneath the specified level. Available levels and order
+are:
+
+- **"info"** _(default)_
+- **"warn"**
+- **"error"**
+- **"trace"**
+- **"debug"**
+- **"silent"**
+
+Type: (`"info"` \| `"warn"` \| `"error"` \| `"trace"` \| `"debug"` \| `"silent"`)
+
+### PreloadStrategy
+
+The mechanism to use for lazy-loading stylesheets.
+_[JS]_ indicates that a strategy requires JavaScript (falls back to `<noscript>`).
+
+- **default:** Move stylesheet links to the end of the document and insert preload meta tags in their place.
+- **"body":** Move all external stylesheet links to the end of the document.
+- **"media":** Load stylesheets asynchronously by adding `media="not x"` and removing once loaded. _[JS]_
+- **"swap":** Convert stylesheet links to preloads that swap to `rel="stylesheet"` once loaded. _[JS]_
+- **"js":** Inject an asynchronous CSS loader similar to [LoadCSS](https://github.com/filamentgroup/loadCSS) and use it to load stylesheets. _[JS]_
+- **"js-lazy":** Like `"js"`, but the stylesheet is disabled until fully loaded.
+
+Type: (default | `"body"` \| `"media"` \| `"swap"` \| `"js"` \| `"js-lazy"`)
+
