 ## Configuration
 
 Add the plugin to your _eleventy.js_ config and provide a [`URL`](https://developer.mozilla.org/en-US/docs/Web/API/URL) for all _top level_ custom element definitions you use.
 ```js
-const path = require('path');
-const { pathToFileURL } = require('url');

 ## Usage
 
 ### 1. Create a Custom Element
+
 Write a custom element like below.  In this case, we are using [Declarative Shadow DOM](https://web.dev/declarative-shadow-dom/).
+
 ```js
-// src/js/greeting.js
+// src/components/greeting.js
 const template = document.createElement('template');
 
 template.innerHTML = `
   <p>Hello from the greeting component!</p>
 `;

 }
 
-module.exports = GreetingComponent; // using module.exports!

 ```
 
-> **Note**: Since [Eleventy does not support ESM yet](https://github.com/11ty/eleventy/issues/836), you will need to use `module.exports = XXX` instead of `export default XXX` for your definitions.

 ### 2. Update Configuration
+
 Add your custom element paths to your _.eleventy.js_ config
+
 ```js
-const path = require('path');
-const { pathToFileURL } = require('url');
-const wccPlugin = require('eleventy-plugin-wcc');
+import { wccPlugin } from './src/index.js';
