+Blur admin uses [Angular UI router](https://github.com/angular-ui/ui-router) for navigation. 
+That means to create new page you need to basically configure `ui-router` state.
+
+We strongly recommend to follow pages structure in our application. 
+If it doesn't fit your needs please create a GitHub issue and tell us why. We would be glad to discuss. 
+
+Also we recommend to put pages to separate modules. 
+This will allow you to easily switch off some pages in the future if needed.
+
+## Page creation example
+
+0) Let's assume we want to create a blank page with title 'My New Page'
+
+1) Create new folder to contain `myNewPage` inside of `src/app/pages`. Let's call it `myNewPage` as well.
+
+2) Then let's create blank angular module to contain our page called 'myNewPage.module.js' inside of `src/app/pages/myNewPage`:
+
+```javascript
+(function () {
+  'use strict';
+
+  angular.module('BlurAdmin.pages.myNewPage', [])
+      .config(routeConfig);
+
+  /** @ngInject */
+  function routeConfig($stateProvider) {
+   
+  }
+
+})();
+```
+
+3) Then let's create empty html file called `my-new-page.html` inside of `src/app/pages/myNewPage`.
+
+4) Lastly let's create ui router state for this page. To do this we need to modify :
+```javascript
+(function () {
+  'use strict';
+
+  angular.module('BlurAdmin.pages.myNewPage', [])
+      .config(routeConfig);
+
+  /** @ngInject */
+  function routeConfig($stateProvider) {
+    $stateProvider
+        .state('myNewPage', {
+          url: '/myNewPage',
+          templateUrl: 'app/pages/myNewPage/my-new-page.html',
+          title: 'My New Page',
+          sidebarMeta: {
+            order: 800,
+          },
+        });
+  }
+
+})();
+```
+
+That's it! Your can now open your new page either from sidebar or through hash URL.
