-## Usage
-
-I recommend using an optimized build matching your Node.js environment version, otherwise, the standard `require` would work just fine with any version of Node `>= v4.0` .
-
-```js
-/*
- * Node 7
- */
-const metalsmith-imagemin = require('metalsmith-imagemin/lib/node7')
-
-/*
- * Node 6
- */
-const metalsmith-imagemin = require('metalsmith-imagemin/lib/node6')
-
-/*
- * Node 4 (Default)
- * Note: additional ES2015 polyfills may be required
- */
-var metalsmith-imagemin = require('metalsmith-imagemin')
-```
-
 ## API
 
 Pass `options` to the imagemin plugin and pass it to Metalsmith with the `use` method:
 
 ```js
-var Metalsmith = require('metalsmith')
-var imagemin = require('metalsmith-imagemin');
+const Metalsmith = require('metalsmith')
+const imagemin = require('metalsmith-imagemin');
 
-var metalsmith = new Metalsmith(__dirname)

   .use(imagemin({
     optimizationLevel: 3,
     svgoPlugins: [{ removeViewBox: false }]
