+
+> Reduce [custom identifiers][idents] with PostCSS.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/postcss-reduce-idents) do:
+
+```
+npm install postcss-reduce-idents --save
+```
+
+
+## Example
+
+### Input
+
+This module will rename custom identifiers in your CSS files; it does so by
+converting each name to a index, which is then encoded into a legal identifier.
+A legal custom identifier in CSS is case sensitive and must start with a
+letter, but can contain digits, hyphens and underscores. There are over 3,000
+possible two character identifiers, and 51 possible single character identifiers
+that will be generated.
+
+```css
+@keyframes whiteToBlack {
+    0% {
+        color: #fff
+    }
+    to {
+        color: #000
+    }
+}
+
+.one {
+    animation-name: whiteToBlack
+}
+```
+
+### Output
+
+```css
+@keyframes a {
+    0% {
+        color: #fff
+    }
+    to {
+        color: #000
+    }
+}
+
+.one {
+    animation-name: a
+}
+```
+
+Note that this module does not handle identifiers that are not linked together.
+The following example will not be transformed in any way:
+
+```css
+@keyframes fadeOut {
+    0% { opacity: 1 }
+    to { opacity: 0 }
+}
+
+.fadeIn {
+    animation-name: fadeIn;
+}
+```
+
+It works for `@keyframes`, `@counter-style`, custom `counter` values and grid area definitions. See the
+[documentation][idents] for more information, or the [tests](src/__tests__) for more
+examples.
+
+
+## Usage
+
+See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
+examples for your environment.
