 In many cases, your engine code may be served from a static server, typically a CDN; this server will probably not share the same root location as your application. In order to specify the location to get the engine assets, you can implement a `generateURI` function in the host application's `ember-cli-build.js` file:
 
 ```js
 // host-app/ember-cli-build.js
 let app = new EmberApp(defaults, {
   assetLoader: {
-    generateURI: function(filePath) {
+    generateURI(filePath) {
       if (EmberApp.env() === 'production') {
-        return 'https://production.cdn.com/' + filePath;
+        return `https://production.cdn.com/${filePath}`;
       } else {
-        return 'local/static/' + filePath;
+        return `local/static/${filePath}`;
       }
     }
   }
 });
 ```
 
 The `generateURI` function receives the `filePath` for each asset and must return a string of the asset's location. For more info, see the [ember-asset-loader documentation](https://github.com/ember-engines/ember-asset-loader#generating-custom-uris).

+### Fastboot
+
+Ember Engines is perfect for combining with Server-side rendering solution and works with [FastBoot](https://ember-fastboot.com/) out of the box.
+
+All Engine builds (regardless of lazy loading or not) will generate a `engines-dist/engine-name/config/environment.js` file. This is because we need to load that file in FastBoot for both eager and lazy engines.
