+### Lazy Loaded Routes/Modules (Angular 2.4.4, Angular CLI 1.0.0-beta.26)
+```javascript
+// app/home/home.module.ts
+import { NgModule } from '@angular/core';
+import { CommonModule } from '@angular/common';
+import { RouterModule, Routes } from '@angular/router';
+import { HomeComponent } from './home.component';
+
+const routes: Routes = [
+  {
+    path: '',
+    component: HomeComponent,
+  },
+];
+
+@NgModule({
+  imports: [
+    CommonModule,
+    RouterModule.forChild(routes),
+  ],
+  exports: [ HomeComponent ],
+  declarations: [ HomeComponent ],
+})
+export class HomeModule { }
+```
+```javascript
+// app/app-routing.module.ts
+import { NgModule } from '@angular/core';
+import { RouterModule, Routes } from '@angular/router';
+
+const routes: Routes = [
+  {
+    path: '',
+    loadChildren: './home/home.module#HomeModule',
+  },
+];
+
+@NgModule({
+  imports: [ RouterModule.forRoot(routes) ],
+  exports: [ RouterModule ]
+})
+export class AppRoutingModule {}
+```
+
+
+## Method of adding modules in the main app-routing.module.ts
+```javascript
+import { NgModule }             from '@angular/core';
+import { RouterModule, Routes } from '@angular/router';
+
+// import { CanActivateViaAuthGuard } from './services';
+import { ErrorComponent } from './error/error.component';
+
+
+const routes: Routes = [
+  {
+    path: '',
+    loadChildren: 'app/home/home.module#HomeModule',
+    // canActivate: [ CanActivateViaAuthGuard ],  // auth protection
+  },
+  {
+    path: 'login',
+    loadChildren: 'app/login/login.module#LoginModule',
+  },
+  {
+    path: 'careers',
+    loadChildren: 'app/careers/careers.module#CareersModule',
+  },
+  {
+    path: 'contact',
+    loadChildren: 'app/contact/contact.module#ContactModule',
+  },
+  {
+    path: 'press',
+    loadChildren: 'app/press/press.module#PressModule',
+  },
+  {
+    path: 'team',
+    loadChildren: 'app/team/team.module#TeamModule',
+  },
+  {
+    path: '**',
+    component: ErrorComponent,
+    data: { title: 'Page Not Found'},  // because title str should differ from path str
+  },
+];
+
+
+@NgModule({
+  imports: [ RouterModule.forRoot(routes) ],
+  exports: [ RouterModule ]
+})
+export class AppRoutingModule {}
