+# [postcss][postcss]-discard-duplicates
+
+> Discard duplicate rules in your CSS files with PostCSS.
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-discard-duplicates) do:
+
+```
+npm install postcss-discard-duplicates --save
+```
+
+## Example
+
+This module will remove all duplicate rules from your stylesheets. It works on
+at rules, normal rules and declarations. Note that this module does not have any
+responsibility for normalising declarations, selectors or whitespace, so that it
+considers these two rules to be different:
+
+```css
+h1, h2 {
+    color: blue;
+}
+
+h2, h1 {
+    color: blue;
+}
+```
+
+It has to assume that your rules have already been transformed by another
+processor, otherwise it would be responsible for too many things.
+
+### Input
+
+```css
+h1 {
+    margin: 0 auto;
+    margin: 0 auto
+}
+
+h1 {
+    margin: 0 auto
+}
+```
+
+### Output
+
+```css
+h1 {
+    margin: 0 auto
+}
+```
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
