+# 2.0.4
+
+* Now compiled with Babel 6.
+
+# 2.0.3
+
+* Fixes an issue where comments that were removed from selectors were replaced
+  by a single space.
+
+# 2.0.2
+
+* Fixes an integration issue where comments inside values transformed by other
+  processors had their values reset to their original state before the
+  comments were removed.
+
+# 2.0.1
+
+* Replaces a dependency on node-balanced with internal comments parser.
+
+# 2.0.0
+
+* Upgraded to PostCSS 5 (thanks to @avanes).
+
+# 1.2.1
+
+* Improved performance by iterating the AST in a single pass.
+
+# 1.2.0
+
+* Adds support for user-directed removal of comments, with the `remove`
+  option (thanks to @dmitrykiselyov).
+* `removeAllButFirst` now operates on each CSS tree, rather than the first one
+  passed to the plugin.
+* Fixes to pass the PostCSS plugin guidelines.
+
+# 1.1.3
+
+* As PostCSS handles the source map content, there is no need to check for
+  the existence of a '#' at position 0 of the comment. This patch fixes this
+  behaviour.
+
+# 1.1.2
+
+* Fixes an issue where comment separated values were being incorrectly
+  transformed to not have spaces separating them instead, in `decl.value`.
+  e.g. `10px/*test*/20px` became `10px20px` in `decl.value` but not
+  `decl._value.raw`.
+
+# 1.1.1
+
+* Fixes a bug where non-special comments, with an exclamation mark in any part
+  of the text, were not being removed.
+
+# 1.1.0
+
+* Now uses the PostCSS `4.1` plugin API.
+* Adds support for transforming comments inside `!important` values.
+
+# 1.0.2
+
+* Adds a JSHint config, tidy up unnecessary lines of code.
+
+# 1.0.1
+
+* Fixed a bug which affected initializing the plugin with no options.
+* Stopped the plugin from trying to match comments in empty strings.
+
+# 1.0.0
+
+* Initial release.

+# [postcss][postcss]-discard-comments [![Build Status](https://travis-ci.org/ben-eb/postcss-discard-comments.svg?branch=master)][ci] [![NPM version](https://badge.fury.io/js/postcss-discard-comments.svg)][npm] [![Dependency Status](https://gemnasium.com/ben-eb/postcss-discard-comments.svg)][deps]
+
+> Discard comments in your CSS files with PostCSS.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-discard-comments) do:
+
+```
+npm install postcss-discard-comments --save
+```
+
+
+## Example
+
+### Input
+
+```css
+h1/* heading */{
+    margin: 0 auto
+}
+```
+
+### Output
+
+```css
+h1 {
+    margin: 0 auto
+}
+```
+
+This module discards comments from your CSS files; by default, it will remove
+all regular comments (`/* comment */`) and preserve comments marked as important
+(`/*! important */`).
+
+Note that this module does not handle source map comments because they are not
+available to it; PostCSS handles this internally, so if they are removed then
+you will have to [configure source maps in PostCSS][maps].
+
+[maps]: https://github.com/postcss/postcss/blob/master/docs/source-maps.md
+
+
+## API
+
+### comments([options])
+
+#### options
+
+##### remove(function)
+
+Type: `function`
+Return: `boolean`
+Variable: `comment` contains a comment without `/**/`
+
+For each comment, return true to remove, or false to keep the comment.
+
+```js
+function(comment) {}
+```
+
+```js
+var css = '/* headings *//*@ h1 */h1{margin:0 auto}/*@ h2 */h2{color:red}';
+console.log(postcss(comments({
+    remove: function(comment) { return comment[0] == "@"; }
+})).process(css).css);
+//=> /* headings */h1{margin:0 auto}h2{color:red}
+```
+**NOTE:** If you use the `remove` function other options will not be available.
+
+##### removeAll
+
+Type: `boolean`
+Default: `false`
+
+Remove all comments marked as important.
+
+```js
+var css = '/*! heading */h1{margin:0 auto}/*! heading 2 */h2{color:red}';
+console.log(postcss(comments({removeAll: true})).process(css).css);
+//=> h1{margin:0 auto}h2{color:red}
+```
+
+##### removeAllButFirst
+
+Type: `boolean`
+Default: `false`
+
+Remove all comments marked as important, but the first one.
+
+```js
+var css = '/*! heading */h1{margin:0 auto}/*! heading 2 */h2{color:red}';
+console.log(postcss(comments({removeAllButFirst: true})).process(css).css);
+//=> /*! heading */h1{margin:0 auto}h2{color:red}
+```
+
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
