+
+```bash

+
+## Usage
+
+Use [PostCSS Clamp] as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssClamp = require('postcss-clamp');
+
+postcss([
+  postcssClamp(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Clamp] runs in all Node environments, with special instructions for:
+
+| [Node](INSTALL.md#node) | [PostCSS CLI](INSTALL.md#postcss-cli) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |

+
+## Options
+
+### precalculate
+
+The `precalculate` option determines whether values with the same unit
+should be precalculated. By default, these are not precalculation.
+
+```js
+postcssColorHexAlpha({
+  precalculate: true
+});
+```
+
+The second and third value has the same unit (`px`):
+
+```css
+.foo {
+  width: clamp(10em, 4px, 10px);
+}
+
+/* becomes */
+
+.foo {
+  width: max(10em, 14px);
+}
+```
+
+Here all values have the same unit:
+
+```css
+.foo {
+  width: clamp(10px, 4px, 10px);
+}
+
+/* becomes */
+
+.foo {
+  width: 24px;
+}
+```
