+
+[PostCSS Environment Variables] lets you use `env()` variables in CSS,
+following the [CSS Environment Variables] specification.
+
+```pcss
+@media (max-width: env(--branding-small)) {
+  body {
+    padding: env(--branding-padding);
+  }
+}
+
+/* becomes */
+
+@media (min-width: 600px) {
+  body {
+    padding: 20px;
+  }
+}
+
+/* when the `importFrom` option is: {
+  "environmentVariables": {
+    "--branding-small": "600px",
+    "--branding-padding": "20px"
+  }
+} */
+```
+
+## Usage
+
+Add [PostCSS Environment Variables] to your project:
+
+```bash
+npm install postcss-env-function --save-dev
+```
+
+Use [PostCSS Environment Variables] to process your CSS:
+
+```js
+const postcssEnvFunction = require('postcss-env-function');
+
+postcssEnvFunction.process(YOUR_CSS /*, processOptions, pluginOptions */);
+```
+
+Or use it as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssEnvFunction = require('postcss-env-function');
+
+postcss([
+  postcssEnvFunction(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Environment Variables] 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
+
+### importFrom
+
+The `importFrom` option specifies sources where Environment Variables can be
+imported from, which might be JS and JSON files, functions, and directly passed
+objects.
+
+```js
+postcssCustomProperties({
+  importFrom: 'path/to/file.js' /* module.exports = {
+      environmentVariables: {
+        '--branding-padding': '20px',
+        '--branding-small': '600px'
+      }
+    } */
+});
+```
+
+```pcss
+@media (max-width: env(--branding-small)) {
+  body {
+    padding: env(--branding-padding);
+  }
+}
+
+/* becomes */
+
+@media (min-width: 600px) {
+  body {
+    padding: 20px;
+  }
+}
+```
+
+Multiple sources can be passed into this option, and they will be parsed in the
+order they are received. JavaScript files, JSON files, functions, and objects
+will need to namespace Custom Properties using the `environmentVariables` or
+`variables-variables` key.
+
+```js
+postcssCustomProperties({
+  importFrom: [
+    'path/to/file.js', // module.exports = { environmentVariables: { '--branding-padding': '20px' } }
+    'and/then/this.json', // { "environment-variables": { "--branding-padding": "20px" } }
+    {
+      environmentVariables: { '--branding-padding': '20px' }
+    },
+    () => {
+      const environmentVariables = { '--branding-padding': '20px' };
+
+      return { environmentVariables };
+    }
+  ]
+});
+```

+[JSON](test/import-variables.json).
