 When localizing a Blazor app, make sure you are familiar with the way localization works in the framework. You can start from the following resources:
 
-* [Localization in Blazor](https://docs.microsoft.com/en-us/aspnet/core/blazor/components?view=aspnetcore-3.0#localization)
+* [Globalization and Localization in Blazor](https://docs.microsoft.com/en-us/aspnet/core/blazor/globalization-localization?view=aspnetcore-3.1)
 * [Localization in ASP.NET Core](https://docs.microsoft.com/en-us/aspnet/core/fundamentals/localization?view=aspnetcore-3.0)
 
+>tip You can find sample runnable projects for both server-side Blazor and for WebAssembly in the [Telerik Blazor UI Samples Repo](https://github.com/telerik/blazor-ui/tree/master/common/localization/).
+>
+>You can also find an example server-side implementation in our offline demos project that are available your Telerik UI for Blazor installation (both [msi]({%slug installation/msi%}) and [zip]({%slug installation/zip%})).

+### Walkthrough - How to Add Globalization and Localization to a Server-side Blazor App
+
+This section will show a tutorial on how to add globalization and localization to a server-side Blazor app. For a WebAssemly app, chek out the [ClientLocalizationResx sample project](https://github.com/telerik/blazor-ui/tree/master/common/localization/ClientLocalizationResx).
+
 The necessary steps are to:
 
 1. Enable the .NET Core localization services.
 1. Implement the UI culture storage (for example, a cookie).
 1. Optionally, add UI that will let the user change the culture so you can test how this works (for example, a dropdownlist that will redirect to the appropriate controller). Alternatively, you can hardcode the `options.DefaultRequestCulture` in the `ConfigureServices` method inside `Startup.cs` when generating the options for the framework localization service.
 1. Implement a service for localizing the Telerik components - it must return the desired string based on the current culture and the requested key (see the explanations above).
 
->note The code snippets below will showcase a sample implementation for a server-side app. For a client-side app, some framework configurations my differ and you cannot use `.resx` files because the framework does not support them.

->note When following this tutorial to add localization to an existing app, make sure to compare the configuration you are copying so that you do not remove configuration necessary for your app.
