 ## Options
 
-### Configuration
-
-To use your own PostCSS configuration, you'll need to create _two (2)_ config files in the root of your project, by which you can provide your own custom plugins / settings that you've installed.
-- _postcss.config.js_
-- _postcss.config.mjs_
-
-Example:
-
-```javascript
-// postcss.config.js
-module.exports = {
-  plugins: [
-    require('postcss-nested')
-  ]
-};
-
-// postcss.config.mjs
-export default {
-  plugins: [
-    (await import('postcss-nested')).default
-  ]
-};
-```
-
-_Eventually once [PostCSS adds support for ESM configuration files](https://github.com/postcss/postcss-cli/issues/387), then this will drop to only needing one file._
-
 ### Extend Config
 
 If you would like to _extend_ the default configuration with your own custom _postcss.config.js_, you can enable the `extendConfig` option of this plugin
