+**`webpack-dashboard@^2.1.1` requires Node 8 or above.** Previous versions support down to Node 6.

 First, import the plugin and add it to your webpack config, or apply it to your compiler:
 
 ```js
 // Import the plugin:
-var DashboardPlugin = require('webpack-dashboard/plugin');
+var DashboardPlugin = require("webpack-dashboard/plugin");
 
 // If you aren't using express, add it to your webpack configs plugins section:
-plugins: [
-    new DashboardPlugin()
-]
+plugins: [new DashboardPlugin()];
 
 // If you are using an express based dev server, add it with compiler.apply
 compiler.apply(new DashboardPlugin());
 ```

 ```js
-plugins: [
-    new DashboardPlugin({ port: 3001 })
-]
+plugins: [new DashboardPlugin({ port: 3001 })];
 ```
