+# Buffer From
+
+A [ponyfill](https://ponyfill.com) for `Buffer.from`, uses native implementation if available.
+
+## Installation
+
+```sh
+npm install --save buffer-from
+```
+
+## Usage
+
+```js
+const bufferFrom = require('buffer-from')
+
+console.log(bufferFrom([1, 2, 3, 4]))
+//=> <Buffer 01 02 03 04>
+
+const arr = new Uint8Array([1, 2, 3, 4])
+console.log(bufferFrom(arr.buffer, 1, 2))
+//=> <Buffer 02 03>
+
+console.log(bufferFrom('test', 'utf8'))
+//=> <Buffer 74 65 73 74>
+
+const buf = bufferFrom('test')
+console.log(bufferFrom(buf))
+//=> <Buffer 74 65 73 74>
+```
+
+## API
+
+### bufferFrom(array)
+
+- `array` &lt;Array&gt;
+
+Allocates a new `Buffer` using an `array` of octets.
+
+### bufferFrom(arrayBuffer[, byteOffset[, length]])
+
+- `arrayBuffer` &lt;ArrayBuffer&gt; The `.buffer` property of a TypedArray or ArrayBuffer
+- `byteOffset` &lt;Integer&gt; Where to start copying from `arrayBuffer`. **Default:** `0`
+- `length` &lt;Integer&gt; How many bytes to copy from `arrayBuffer`. **Default:** `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a TypedArray instance, the
+newly created `Buffer` will share the same allocated memory as the TypedArray.
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+### bufferFrom(buffer)
+
+- `buffer` &lt;Buffer&gt; An existing `Buffer` to copy data from
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+### bufferFrom(string[, encoding])
+
+- `string` &lt;String&gt; A string to encode.
+- `encoding` &lt;String&gt; The encoding of `string`. **Default:** `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `string`. If
+provided, the `encoding` parameter identifies the character encoding of
+`string`.

+# Node.js version support
+
+clean-css requires Node.js 4.0+ (tested on Linux, OS X, and Windows)
+
+# Install
+
+```
+npm install --save-dev clean-css
+```
+
+# Use
+
+```js
+var CleanCSS = require('clean-css');
+var input = 'a{font-weight:bold;}';
+var options = { /* options */ };
+var output = new CleanCSS(options).minify(input);
+```
+
+## Important: 4.0 breaking changes
+
+clean-css 4.0 introduces some breaking changes:
+
+* API and CLI interfaces are split, so API stays in this repository while CLI moves to [clean-css-cli](https://github.com/jakubpawlowicz/clean-css-cli);
+* `root`, `relativeTo`, and `target` options are replaced by a single `rebaseTo` option - this means that rebasing URLs and import inlining is much simpler but may not be (YMMV) as powerful as in 3.x;
+* `debug` option is gone as stats are always provided in output object under `stats` property;
+* `roundingPrecision` is disabled by default;
+* `roundingPrecision` applies to **all** units now, not only `px` as in 3.x;
+* `processImport` and `processImportFrom` are merged into `inline` option which defaults to `local`. Remote `@import` rules are **NOT** inlined by default anymore;
+* splits `inliner: { request: ..., timeout: ... }` option into `inlineRequest` and `inlineTimeout` options;
+* remote resources without a protocol, e.g. `//fonts.googleapis.com/css?family=Domine:700`, are not inlined anymore;
+* changes default Internet Explorer compatibility from 9+ to 10+, to revert the old default use `{ compatibility: 'ie9' }` flag;
+* renames `keepSpecialComments` to `specialComments`;
+* moves `roundingPrecision` and `specialComments` to level 1 optimizations options, see examples;
+* moves `mediaMerging`, `restructuring`, `semanticMerging`, and `shorthandCompacting` to level 2 optimizations options, see examples below;
+* renames `shorthandCompacting` option to `mergeIntoShorthands`;
+* level 1 optimizations are the new default, up to 3.x it was level 2;
+* `keepBreaks` option is replaced with `{ format: 'keep-breaks' }` to ease transition;
+* `sourceMap` option has to be a boolean from now on - to specify an input source map pass it a 2nd argument to `minify` method or via a hash instead;
+* `aggressiveMerging` option is removed as aggressive merging is replaced by smarter override merging.
+
+## What's new in version 4.1
+
+clean-css 4.1 introduces the following changes / features:
+
+* `inline: false` as an alias to `inline: ['none']`;
+* `multiplePseudoMerging` compatibility flag controlling merging of rules with multiple pseudo classes / elements;
+* `removeEmpty` flag in level 1 optimizations controlling removal of rules and nested blocks;
+* `removeEmpty` flag in level 2 optimizations controlling removal of rules and nested blocks;
+* `compatibility: { selectors: { mergeLimit: <number> } }` flag in compatibility settings controlling maximum number of selectors in a single rule;
+* `minify` method improved signature accepting a list of hashes for a predictable traversal;
+* `selectorsSortingMethod` level 1 optimization allows `false` or `'none'` for disabling selector sorting;
+* `fetch` option controlling a function for handling remote requests;
+* new `font` shorthand and `font-*` longhand optimizers;
+* removal of `optimizeFont` flag in level 1 optimizations due to new `font` shorthand optimizer;
+* `skipProperties` flag in level 2 optimizations controlling which properties won't be optimized;
+* new `animation` shorthand and `animation-*` longhand optimizers;
+* `removeUnusedAtRules` level 2 optimization controlling removal of unused `@counter-style`, `@font-face`, `@keyframes`, and `@namespace` at rules;
+* the [web interface](https://jakubpawlowicz.github.io/clean-css) gets an improved settings panel with "reset to defaults", instant option changes, and settings being persisted across sessions.
+
+## What's new in version 4.2
+
+clean-css 4.2 introduces the following changes / features:
+
+* Adds `process` method for compatibility with optimize-css-assets-webpack-plugin;
+* new `transition` property optimizer;
+* preserves any CSS content between `/* clean-css ignore:start */` and `/* clean-css ignore:end */` comments;
+* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
+* adds configurable line breaks via `format: { breakWith: 'lf' }` option.
+
+## Constructor options
+
+clean-css constructor accepts a hash as a parameter with the following options available:
+
+* `compatibility` - controls compatibility mode used; defaults to `ie10+`; see [compatibility modes](#compatibility-modes) for examples;
+* `fetch` - controls a function for handling remote requests; see [fetch option](#fetch-option) for examples (since 4.1.0);
+* `format` - controls output CSS formatting; defaults to `false`; see [formatting options](#formatting-options) for examples;
+* `inline` - controls `@import` inlining rules; defaults to `'local'`; see [inlining options](#inlining-options) for examples;
+* `inlineRequest` - controls extra options for inlining remote `@import` rules, can be any of [HTTP(S) request options](https://nodejs.org/api/http.html#http_http_request_options_callback);
+* `inlineTimeout` - controls number of milliseconds after which inlining a remote `@import` fails; defaults to 5000;
+* `level` - controls optimization level used; defaults to `1`; see [optimization levels](#optimization-levels) for examples;
+* `rebase` - controls URL rebasing; defaults to `true`;
+* `rebaseTo` - controls a directory to which all URLs are rebased, most likely the directory under which the output file will live; defaults to the current directory;
+* `returnPromise` - controls whether `minify` method returns a Promise object or not; defaults to `false`; see [promise interface](#promise-interface) for examples;
+* `sourceMap` - controls whether an output source map is built; defaults to `false`;
+* `sourceMapInlineSources` - controls embedding sources inside a source map's `sourcesContent` field; defaults to false.
+
+## Compatibility modes
+
+There is a certain number of compatibility mode shortcuts, namely:
+
+* `new CleanCSS({ compatibility: '*' })` (default) - Internet Explorer 10+ compatibility mode
+* `new CleanCSS({ compatibility: 'ie9' })` - Internet Explorer 9+ compatibility mode
+* `new CleanCSS({ compatibility: 'ie8' })` - Internet Explorer 8+ compatibility mode
+* `new CleanCSS({ compatibility: 'ie7' })` - Internet Explorer 7+ compatibility mode
+
+Each of these modes is an alias to a [fine grained configuration](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/options/compatibility.js), with the following options available:
+
+```js
+new CleanCSS({
+  compatibility: {
+    colors: {
+      opacity: true // controls `rgba()` / `hsla()` color support
+    },
+    properties: {
+      backgroundClipMerging: true, // controls background-clip merging into shorthand
+      backgroundOriginMerging: true, // controls background-origin merging into shorthand

+      colors: true, // controls color optimizations
+      ieBangHack: false, // controls keeping IE bang hack
+      ieFilters: false, // controls keeping IE `filter` / `-ms-filter`
+      iePrefixHack: false, // controls keeping IE prefix hack
+      ieSuffixHack: false, // controls keeping IE suffix hack
+      merging: true, // controls property merging based on understandability
+      shorterLengthUnits: false, // controls shortening pixel units into `pc`, `pt`, or `in` units
+      spaceAfterClosingBrace: true, // controls keeping space after closing brace - `url() no-repeat` into `url()no-repeat`
+      urlQuotes: false, // controls keeping quoting inside `url()`
+      zeroUnits: true // controls removal of units `0` value
+    },
+    selectors: {
+      adjacentSpace: false, // controls extra space before `nav` element
+      ie7Hack: true, // controls removal of IE7 selector hacks, e.g. `*+html...`
+      mergeablePseudoClasses: [':active', ...], // controls a whitelist of mergeable pseudo classes
+      mergeablePseudoElements: ['::after', ...], // controls a whitelist of mergeable pseudo elements
+      mergeLimit: 8191, // controls maximum number of selectors in a single rule (since 4.1.0)
+      multiplePseudoMerging: true // controls merging of rules with multiple pseudo classes / elements (since 4.1.0)
+    },
+    units: {
+      ch: true, // controls treating `ch` as a supported unit
+      in: true, // controls treating `in` as a supported unit

+      vmin: true // controls treating `vmin` as a supported unit
+    }
+  }
+})
+```
+
+You can also use a string when setting a compatibility mode, e.g.
+
+```js
+new CleanCSS({
+  compatibility: 'ie9,-properties.merging' // sets compatibility to IE9 mode with disabled property merging
+})
+```
+
+## Fetch option
+
+The `fetch` option accepts a function which handles remote resource fetching, e.g.
+
+```js
+var request = require('request');
+var source = '@import url(http://example.com/path/to/stylesheet.css);';
+new CleanCSS({
+  fetch: function (uri, inlineRequest, inlineTimeout, callback) {
+    request(uri, function (error, response, body) {
+      if (error) {
+        callback(error, null);
+      } else if (response && response.statusCode != 200) {
+        callback(response.statusCode, null);
+      } else {
+        callback(null, body);
+      }
+    });
+  }
+}).minify(source);
+```
+
+This option provides a convenient way of overriding the default fetching logic if it doesn't support a particular feature, say CONNECT proxies.
+
+Unless given, the default [loadRemoteResource](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/reader/load-remote-resource.js) logic is used.
+
+## Formatting options
+
+By default output CSS is formatted without any whitespace unless a `format` option is given.
+First of all there are two shorthands:
+
+```js
+new CleanCSS({
+  format: 'beautify' // formats output in a really nice way
+})
+```
+
+and
+
+```js
+new CleanCSS({
+  format: 'keep-breaks' // formats output the default way but adds line breaks for improved readability
+})
+```
+
+however `format` option also accept a fine-grained set of options:
+
+```js
+new CleanCSS({
+  format: {
+    breaks: { // controls where to insert breaks
+      afterAtRule: false, // controls if a line break comes after an at-rule; e.g. `@charset`; defaults to `false`
+      afterBlockBegins: false, // controls if a line break comes after a block begins; e.g. `@media`; defaults to `false`
+      afterBlockEnds: false, // controls if a line break comes after a block ends, defaults to `false`
+      afterComment: false, // controls if a line break comes after a comment; defaults to `false`
+      afterProperty: false, // controls if a line break comes after a property; defaults to `false`
+      afterRuleBegins: false, // controls if a line break comes after a rule begins; defaults to `false`
+      afterRuleEnds: false, // controls if a line break comes after a rule ends; defaults to `false`
+      beforeBlockEnds: false, // controls if a line break comes before a block ends; defaults to `false`
+      betweenSelectors: false // controls if a line break comes between selectors; defaults to `false`
+    },
+    breakWith: '\n', // controls the new line character, can be `'\r\n'` or `'\n'` (aliased as `'windows'` and `'unix'` or `'crlf'` and `'lf'`); defaults to system one, so former on Windows and latter on Unix
+    indentBy: 0, // controls number of characters to indent with; defaults to `0`
+    indentWith: 'space', // controls a character to indent with, can be `'space'` or `'tab'`; defaults to `'space'`
+    spaces: { // controls where to insert spaces
+      aroundSelectorRelation: false, // controls if spaces come around selector relations; e.g. `div > a`; defaults to `false`
+      beforeBlockBegins: false, // controls if a space comes before a block begins; e.g. `.block {`; defaults to `false`
+      beforeValue: false // controls if a space comes before a value; e.g. `width: 1rem`; defaults to `false`
+    },
+    wrapAt: false // controls maximum line length; defaults to `false`
+  }
+})
+```
+
+## Inlining options
+
+`inline` option whitelists which `@import` rules will be processed, e.g.
+
+```js
+new CleanCSS({
+  inline: ['local'] // default; enables local inlining only
+})
+```
+
+```js
+new CleanCSS({
+  inline: ['none'] // disables all inlining
+})
+```
+
+```js
+// introduced in clean-css 4.1.0
+
+new CleanCSS({
+  inline: false // disables all inlining (alias to `['none']`)
+})
+```
+
+```js
+new CleanCSS({
+  inline: ['all'] // enables all inlining, same as ['local', 'remote']
+})
+```
+
+```js
+new CleanCSS({
+  inline: ['local', 'mydomain.example.com'] // enables local inlining plus given remote source
+})
+```
+
+```js
+new CleanCSS({
+  inline: ['local', 'remote', '!fonts.googleapis.com'] // enables all inlining but from given remote source
+})
+```
+
+## Optimization levels
+
+The `level` option can be either `0`, `1` (default), or `2`, e.g.
+
+```js
+new CleanCSS({
+  level: 2
+})
+```
+
+or a fine-grained configuration given via a hash.
+
+Please note that level 1 optimization options are generally safe while level 2 optimizations should be safe for most users.
+
+### Level 0 optimizations
+
+Level 0 optimizations simply means "no optimizations". Use it when you'd like to inline imports and / or rebase URLs but skip everything else.
+
+### Level 1 optimizations
+
+Level 1 optimizations (default) operate on single properties only, e.g. can remove units when not required, turn rgb colors to a shorter hex representation, remove comments, etc
+
+Here is a full list of available options:
+
+```js
+new CleanCSS({
+  level: {
+    1: {
+      cleanupCharsets: true, // controls `@charset` moving to the front of a stylesheet; defaults to `true`
+      normalizeUrls: true, // controls URL normalization; defaults to `true`
+      optimizeBackground: true, // controls `background` property optimizations; defaults to `true`
+      optimizeBorderRadius: true, // controls `border-radius` property optimizations; defaults to `true`
+      optimizeFilter: true, // controls `filter` property optimizations; defaults to `true`
+      optimizeFont: true, // controls `font` property optimizations; defaults to `true`
+      optimizeFontWeight: true, // controls `font-weight` property optimizations; defaults to `true`
+      optimizeOutline: true, // controls `outline` property optimizations; defaults to `true`
+      removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
+      removeNegativePaddings: true, // controls removing negative paddings; defaults to `true`
+      removeQuotes: true, // controls removing quotes when unnecessary; defaults to `true`
+      removeWhitespace: true, // controls removing unused whitespace; defaults to `true`
+      replaceMultipleZeros: true, // contols removing redundant zeros; defaults to `true`
+      replaceTimeUnits: true, // controls replacing time units with shorter values; defaults to `true`
+      replaceZeroUnits: true, // controls replacing zero values with units; defaults to `true`
+      roundingPrecision: false, // rounds pixel values to `N` decimal places; `false` disables rounding; defaults to `false`
+      selectorsSortingMethod: 'standard', // denotes selector sorting method; can be `'natural'` or `'standard'`, `'none'`, or false (the last two since 4.1.0); defaults to `'standard'`
+      specialComments: 'all', // denotes a number of /*! ... */ comments preserved; defaults to `all`
+      tidyAtRules: true, // controls at-rules (e.g. `@charset`, `@import`) optimizing; defaults to `true`
+      tidyBlockScopes: true, // controls block scopes (e.g. `@media`) optimizing; defaults to `true`
+      tidySelectors: true, // controls selectors optimizing; defaults to `true`,
+      semicolonAfterLastProperty: false, // controls removing trailing semicolons in rule; defaults to `false` - means remove
+      transform: function () {} // defines a callback for fine-grained property optimization; defaults to no-op
+    }
+  }
+});
+```
+
+There is an `all` shortcut for toggling all options at the same time, e.g.
+
+```js
+new CleanCSS({
+  level: {
+    1: {
+      all: false, // set all values to `false`
+      tidySelectors: true // turns on optimizing selectors
+    }
+  }
+});
+```
+
+### Level 2 optimizations
+
+Level 2 optimizations operate at rules or multiple properties level, e.g. can remove duplicate rules, remove properties redefined further down a stylesheet, or restructure rules by moving them around.
+
+Please note that if level 2 optimizations are turned on then, unless explicitely disabled, level 1 optimizations are applied as well.
+
+Here is a full list of available options:
+
+```js
+new CleanCSS({
+  level: {
+    2: {
+      mergeAdjacentRules: true, // controls adjacent rules merging; defaults to true
+      mergeIntoShorthands: true, // controls merging properties into shorthands; defaults to true
+      mergeMedia: true, // controls `@media` merging; defaults to true
+      mergeNonAdjacentRules: true, // controls non-adjacent rule merging; defaults to true
+      mergeSemantically: false, // controls semantic merging; defaults to false
+      overrideProperties: true, // controls property overriding based on understandability; defaults to true
+      removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
+      reduceNonAdjacentRules: true, // controls non-adjacent rule reducing; defaults to true
+      removeDuplicateFontRules: true, // controls duplicate `@font-face` removing; defaults to true
+      removeDuplicateMediaBlocks: true, // controls duplicate `@media` removing; defaults to true
+      removeDuplicateRules: true, // controls duplicate rules removing; defaults to true
+      removeUnusedAtRules: false, // controls unused at rule removing; defaults to false (available since 4.1.0)
+      restructureRules: false, // controls rule restructuring; defaults to false
+      skipProperties: [] // controls which properties won't be optimized, defaults to `[]` which means all will be optimized (since 4.1.0)
+    }
+  }
+});
+```
+
+There is an `all` shortcut for toggling all options at the same time, e.g.
+
+```js
+new CleanCSS({
+  level: {
+    2: {
+      all: false, // sets all values to `false`
+      removeDuplicateRules: true // turns on removing duplicate rules
+    }
+  }
+});
+```
+
+## Minify method
+
+Once configured clean-css provides a `minify` method to optimize a given CSS, e.g.
+
+```js
+var output = new CleanCSS(options).minify(source);
+```
+
+The output of the `minify` method is a hash with following fields:
+
+```js
+console.log(output.styles); // optimized output CSS as a string
+console.log(output.sourceMap); // output source map if requested with `sourceMap` option
+console.log(output.errors); // a list of errors raised
+console.log(output.warnings); // a list of warnings raised
+console.log(output.stats.originalSize); // original content size after import inlining
+console.log(output.stats.minifiedSize); // optimized content size
+console.log(output.stats.timeSpent); // time spent on optimizations in milliseconds
+console.log(output.stats.efficiency); // `(originalSize - minifiedSize) / originalSize`, e.g. 0.25 if size is reduced from 100 bytes to 75 bytes
+```
+
+The `minify` method also accepts an input source map, e.g.
+
+```js
+var output = new CleanCSS(options).minify(source, inputSourceMap);
+```
+
+or a callback invoked when optimizations are finished, e.g.
+
+```js
+new CleanCSS(options).minify(source, function (error, output) {
+  // `output` is the same as in the synchronous call above
+});
+```
+
+## Promise interface
+
+If you prefer clean-css to return a Promise object then you need to explicitely ask for it, e.g.
+
+```js
+new CleanCSS({ returnPromise: true })
+  .minify(source)
+  .then(function (output) { console.log(output.styles); })
+  .catch(function (error) { // deal with errors });
+```
+
+## CLI utility
+
+Clean-css has an associated command line utility that can be installed separately using `npm install clean-css-cli`. For more detailed information, please visit https://github.com/jakubpawlowicz/clean-css-cli.
+
+# FAQ
+
+## How to optimize multiple files?
+
+It can be done either by passing an array of paths, or, when sources are already available, a hash or an array of hashes:
+
+```js
+new CleanCSS().minify(['path/to/file/one', 'path/to/file/two']);
+```
+
+```js
+new CleanCSS().minify({
+  'path/to/file/one': {
+    styles: 'contents of file one'
+  },
+  'path/to/file/two': {
+    styles: 'contents of file two'
+  }
+});
+```
+
+```js
+new CleanCSS().minify([
+  {'path/to/file/one': {styles: 'contents of file one'}},
+  {'path/to/file/two': {styles: 'contents of file two'}}
+]);
+```
+
+Passing an array of hashes allows you to explicitly specify the order in which the input files are concatenated. Whereas when you use a single hash the order is determined by the [traversal order of object properties](http://2ality.com/2015/10/property-traversal-order-es6.html) - available since 4.1.0.
+
+Important note - any `@import` rules already present in the hash will be resolved in memory.
+
+## How to process remote `@import`s correctly?
+
+In order to inline remote `@import` statements you need to provide a callback to minify method as fetching remote assets is an asynchronous operation, e.g.:
+
+```js
+var source = '@import url(http://example.com/path/to/remote/styles);';
+new CleanCSS({ inline: ['remote'] }).minify(source, function (error, output) {
+  // output.styles
+});
+```
+
+If you don't provide a callback, then remote `@import`s will be left as is.
+
+## How to apply arbitrary transformations to CSS properties?
+
+If clean-css doesn't perform a particular property optimization, you can use `transform` callback to apply it:
+
+```js
+var source = '.block{background-image:url(/path/to/image.png)}';
+var output = new CleanCSS({
+  level: {
+    1: {
+      transform: function (propertyName, propertyValue, selector /* `selector` available since 4.2.0-pre */) {
+        if (propertyName == 'background-image' && propertyValue.indexOf('/path/to') > -1) {
+          return propertyValue.replace('/path/to', '../valid/path/to');
+        }
+      }
+    }
+  }
+}).minify(source);
+
+console.log(output.styles); # => .block{background-image:url(../valid/path/to/image.png)}
+```
+
+Note: returning `false` from `transform` callback will drop a property.
+
+## How to specify a custom rounding precision?
+
+The level 1 `roundingPrecision` optimization option accept a string with per-unit rounding precision settings, e.g.
+
+```js
+new CleanCSS({
+  level: {
+    1: {
+      roundingPrecision: 'all=3,px=5'
+    }
+  }
+}).minify(source)
+```
+
+which sets all units rounding precision to 3 digits except `px` unit precision of 5 digits.
+
+## How to keep a CSS fragment intact?
+
+Note: available in the current master, to be released in 4.2.0.
+
+Wrap the CSS fragment in special comments which instruct clean-css to preserve it, e.g.
+
+```css
+.block-1 {
+  color: red
+}
+/* clean-css ignore:start */
+.block-special {
+  color: transparent
+}
+/* clean-css ignore:end */
+.block-2 {
+  margin: 0
+}
+```
+
+Optimizing this CSS will result in the following output:
+
+```css
+.block-1{color:red}
+.block-special {
+  color: transparent
+}
+.block-2{margin:0}
+```
+
+## How to preserve a comment block?
+
+Use the `/*!` notation instead of the standard one `/*`:
+
+```css
+/*!
+  Important comments included in optimized output.
+*/
+```
+
+## How to rebase relative image URLs?
+
+clean-css will handle it automatically for you in the following cases:
+
+* when full paths to input files are passed in as options;
+* when correct paths are passed in via a hash;
+* when `rebaseTo` is used with any of above two.
+
+## How to work with source maps?
+
+To generate a source map, use `sourceMap: true` option, e.g.:
+
+```js
+new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
+  .minify(source, function (error, output) {
+    // access output.sourceMap for SourceMapGenerator object
+    // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
+});
+```
+
+You can also pass an input source map directly as a 2nd argument to `minify` method:
+
+```js
+new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
+  .minify(source, inputSourceMap, function (error, output) {
+    // access output.sourceMap to access SourceMapGenerator object
+    // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
+});
+```
+
+or even multiple input source maps at once:
+
+```js
+new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory }).minify({
+  'path/to/source/1': {
+    styles: '...styles...',
+    sourceMap: '...source-map...'
+  },
+  'path/to/source/2': {
+    styles: '...styles...',
+    sourceMap: '...source-map...'
+  }
+}, function (error, output) {
+  // access output.sourceMap as above
+});
+```
+
+## How to apply level 1 & 2 optimizations at the same time?
+
+Using the hash configuration specifying both optimization levels, e.g.
+
+```js
+new CleanCSS({
+  level: {
+    1: {
+      all: true,
+      normalizeUrls: false
+    },
+    2: {
+      restructureRules: true
+    }
+  }
+})
+```
+
+will apply level 1 optimizations, except url normalization, and default level 2 optimizations with rule restructuring.
+
+## What level 2 optimizations do?
+
+All level 2 optimizations are dispatched [here](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/optimizer/level-2/optimize.js#L67), and this is what they do:
+
+* `recursivelyOptimizeBlocks` - does all the following operations on a nested block, like `@media` or `@keyframe`;
+* `recursivelyOptimizeProperties` - optimizes properties in rulesets and flat at-rules, like @font-face, by splitting them into components (e.g. `margin` into `margin-(bottom|left|right|top)`), optimizing, and restoring them back. You may want to use `mergeIntoShorthands` option to control whether you want to turn multiple components into shorthands;
+* `removeDuplicates` - gets rid of duplicate rulesets with exactly the same set of properties, e.g. when including a Sass / Less partial twice for no good reason;
+* `mergeAdjacent` - merges adjacent rulesets with the same selector or rules;
+* `reduceNonAdjacent` - identifies which properties are overridden in same-selector non-adjacent rulesets, and removes them;
+* `mergeNonAdjacentBySelector` - identifies same-selector non-adjacent rulesets which can be moved (!) to be merged, requires all intermediate rulesets to not redefine the moved properties, or if redefined to have the same value;
+* `mergeNonAdjacentByBody` - same as the one above but for same-selector non-adjacent rulesets;
+* `restructure` - tries to reorganize different-selector different-rules rulesets so they take less space, e.g. `.one{padding:0}.two{margin:0}.one{margin-bottom:3px}` into `.two{margin:0}.one{padding:0;margin-bottom:3px}`;
+* `removeDuplicateFontAtRules` - removes duplicated `@font-face` rules;
+* `removeDuplicateMediaQueries` - removes duplicated `@media` nested blocks;
+* `mergeMediaQueries` - merges non-adjacent `@media` at-rules by the same rules as `mergeNonAdjacentBy*` above;
+
