+This creates a `customers` folder having the new lazy-loadable feature module `CustomersModule` defined in the `customers.module.ts` file and the routing module `CustomersRoutingModule` defined in the `customers-routing.module.ts` file. The command automatically declares the `CustomersComponent` and imports `CustomersRoutingModule` inside the new feature module.
 
 Because the new module is meant to be lazy-loaded, the command does NOT add a reference to the new feature module in the application's root module file, `app.module.ts`.
 Instead, it adds the declared route, `customers` to the `routes` array declared in the module provided as the `--module` option.
