+This module is based on [Microsoft's Identity library](https://docs.microsoft.com/en-us/aspnet/core/security/authentication/identity) and the [Identity Module](Identity.md). It has [IdentityServer](https://github.com/IdentityServer) integration (based on the [IdentityServer Module](IdentityServer.md)) to provide **single sign-on**, access control and other advanced authentication features.
+
+## How to Install

+This module comes as pre-installed (as NuGet/NPM packages) when you [create a new solution](https://abp.io/get-started) with the ABP Framework. You can continue to use it as package and get updates easily, or you can include its source code into your solution (see `get-source` [CLI](../CLI.md) command) to develop your custom module.

 ## Social/External Logins
 
-The [Account Module](../Modules/Account.md) has already configured to handle social or external logins out of the box. You can follow the ASP.NET Core documentation to add a social/external login provider to your application.

-### Other UI Types
-
-Beginning from the v3.1, the [Angular UI](../UI/Angular/Quick-Start.md) uses authorization code flow (as a best practice) to authenticate the user by redirecting to the MVC UI login page. So, even if you are using the Angular UI, social/external login integration is same as explained above and it will work out of the box. As similar, The [Blazor UI](../UI/Blazor/Overall.md) also uses the MVC UI to logic.
