+#### Enable/Disable Permissions
+
+A permission is enabled by default. It is possible to disable a permission. A disabled permission will be prohibited for everyone. You can still check for the permission, but it will always return prohibited.
+
+Example definition:
+
+````csharp
+myGroup.AddPermission("Author_Management", isEnabled: false);
+````
+
+You normally don't need to define a disabled permission (unless you temporary want disable a feature of your application). However, you may want to disable a permission defined in a depended module. In this way you can disable the related application functionality. See the "*Changing Permission Definitions of a Depended Module*" section below for an example usage.
+
+> Note: Checking an undefined permission will throw an exception while a disabled permission check simply returns prohibited (false).
+
 #### Child Permissions
 
 A permission may have child permissions. It is especially useful when you want to create a hierarchical permission tree where a permission may have additional sub permissions which are available only if the parent permission has been granted.

 A class deriving from the `PermissionDefinitionProvider` (just like the example above) can also get existing permission definitions (defined by the depended [modules](Module-Development-Basics.md)) and change their definitions.
 
+Example:
+
+````csharp
+context
+    .GetPermissionOrNull(IdentityPermissions.Roles.Delete)
+    .IsEnabled = false;
+````
+
+When you write this code inside your permission definition provider, it finds the "role deletion" permission of the [Identity Module](Modules/Identity.md) and disabled the permission, so no one can delete a role on the application.
+
+> Tip: It is better to check the value returned by the `GetPermissionOrNull` method since it may return null if the given permission was not defined.

 ## IAuthorizationService
 
 ASP.NET Core provides the `IAuthorizationService` that can be used to check for authorization. Once you inject, you can use it in your code to conditionally control the authorization.

 You can install any storage for Hangfire. The most common one is SQL Server (see the [Hangfire.SqlServer](https://www.nuget.org/packages/Hangfire.SqlServer) NuGet package).
 
 After you have installed these NuGet packages, you need to configure your project to use Hangfire.
 
 1.First, we change the `Module` class (example: `<YourProjectName>HttpApiHostModule`) to add Hangfire configuration of the storage and connection string in the `ConfigureServices` method:

+# How to Insert Scripts and Styles
+
+You can use the `DomInsertionService` in @abp/ng.core package in order to insert scripts and styles in an easy and explicit way.
+
+
+## Getting Started
+
+You do not have to provide the `DomInsertionService` at module or component level, because it is already **provided in root**. You can inject and start using it immediately in your components, directives, or services.
+
+```js
+import { DomInsertionService } from '@abp/ng.core';
+
+@Component({
+  /* class metadata here */
+})
+class DemoComponent {
+  constructor(private domInsertionService: DomInsertionService) {}
+}
+```
+
+## Usage
+
+You can use the `insertContent` method of `DomInsertionService` to create a `<script>` or `<style>` element with given content in the DOM at the desired position.
+
+
+### How to Insert Scripts
+
+The first parameter of `insertContent` method expects a `ContentStrategy`. If you pass a `ScriptContentStrategy` instance, the `DomInsertionService` will create a `<script>` element with given `content` and place it in the designated DOM position.
+
+```js
+import { DomInsertionService, CONTENT_STRATEGY } from '@abp/ng.core';
+
+@Component({
+  /* class metadata here */
+})
+class DemoComponent {
+  constructor(private domInsertionService: DomInsertionService) {}
+
+  ngOnInit() {
+    this.domInsertionService.insertContent(
+      CONTENT_STRATEGY.AppendScriptToBody('alert()')
+    );
+  }
+}
+```
+
+In the example above, `<script>alert()</script>` element will place at the **end** of `<body>`.
+
+Please refer to [ContentStrategy](./Content-Strategy.md) to see all available content strategies and how you can build your own content strategy.
+
+
+### How to Insert Styles
+
+If you pass a `StyleContentStrategy` instance as the first parameter of `insertContent` method, the `DomInsertionService` will create a `<style>` element with given `content` and place it in the designated DOM position.
+
+```js
+import { DomInsertionService, CONTENT_STRATEGY } from '@abp/ng.core';
+
+@Component({
+  /* class metadata here */
+})
+class DemoComponent {
+  constructor(private domInsertionService: DomInsertionService) {}
+
+  ngOnInit() {
+    this.domInsertionService.insertContent(
+      CONTENT_STRATEGY.AppendStyleToHead('body {margin: 0;}')
+    );
+  }
+}
+```
+
+In the example above, `<style>body {margin: 0;}</style>` element will place at the **end** of `<head>`.
+
+Please refer to [ContentStrategy](./Content-Strategy.md) to see all available content strategies and how you can build your own content strategy.

+# 如何为MVC / Razor页面应用程序自定义登录页面
+
+当你使用[应用程序启动模板](../Startup-Templates/Application.md)创建了一个新的应用程序, 登录页面的源代码并不在你的解决方案中,所以你不能直接更改. 它来自[账户模块](../Modules/Account.md),使用[NuGet包](https://www.nuget.org/packages/Volo.Abp.Account.Web)引用.
+
+本文介绍了如何为自己的应用程序自定义登录页面.
+
+## 创建登录 PageModel
+
+创建一个新的类继承账户模块的[LoginModel](https://github.com/abpframework/abp/blob/037ef9abe024c03c1f89ab6c933710bcfe3f5c93/modules/account/src/Volo.Abp.Account.Web/Pages/Account/Login.cshtml.cs).
+
+````csharp
+public class CustomLoginModel : LoginModel
+{
+    public CustomLoginModel(
+    Microsoft.AspNetCore.Authentication.IAuthenticationSchemeProvider schemeProvider,
+    Microsoft.Extensions.Options.IOptions<Volo.Abp.Account.Web.AbpAccountOptions> accountOptions)
+        : base(schemeProvider, accountOptions)
+        {
+        }
+}
+````
+
+> 在这里命令约定很重要. 如果你的类名不是以 `LoginModel` 结束,你需要手动在[依赖注入](../Dependency-Injection.md)系统替换 `LoginModel`.
+
+然后你可以覆盖任何方法并添加用户界面需要的新方法和属性.
+
+## 重写登录页面UI
+
+在 **Pages** 目录下创建名为 **Account** 的文件夹,并在这个文件夹中创建 `Login.cshtml` ,借助[虚拟文件系统](../Virtual-File-System.md)它会自动覆盖账户模块的页面文件.
+
+自定义页面一个很好的开始是复制它的源代码. [点击这里](https://github.com/abpframework/abp/blob/dev/modules/account/src/Volo.Abp.Account.Web/Pages/Account/Login.cshtml)找到登录页面的源码. 在编写本文档时,源代码如下:
