 ## Using the Wizard
 
-#### Section 1: Choose How to Start the Project
+The **Create New Project** wizard generates a project that is based on the Microsoft template. The app includes some Telerik UI components and the [required NuGet package reference, static assets, localization service, and the `TelerikRootComponent`](slug:getting-started/what-you-need).
 
-The **Telerik UI for Blazor Template Wizard** provides two options to start you project:
+> Earlier versions of the wizard provided the **Admin**, **Dashboard**, **CRUD**, **Form**, and **Chart** templates which are now deprecated. You can find their source code in the [`blazor-ui` repo](https://github.com/telerik/blazor-ui/tree/master/common/legacy-project-templates).
 
-* **Start from Blank App**&mdash;allows you to create a blank project that is pre-configured for the Progress® Telerik® UI for Blazor components. You can select and add sample pages to get started (a Grid with CRUD operations form a service, a Form, Charts).
+The wizard contains the following sections:
 
-* **Start from Template** - the wizard provides a set of predefined project templates:
-    * **CRUD, Form, Chart**&mdash;A small app that showcases the Telerik UI Data Grid, Chart, and Form validation. The Data Grid also uses a basic CRUD service (a common pattern for data updates in production-ready applications).
-    * **Dashboard**&mdash;A basic dashboard that showcases the Telerik UI TileLayout component and how individual blocks (tiles) can fetch data.
-    * **Admin**&mdash;A small app that showcases a dashboard for administrators. The app uses some of the main Telerik UI components like the [Data Grid](slug:grid-overview), [Chart](slug:components/chart/overview), [TileLayout](slug:tilelayout-overview), [Form](slug:form-overview), and more.

-The available templates vary depending on the target framework and hosting model. All of the above templates are available for the Client and Server projects for .NET 6 and .NET 7. The Hybrid projects and the .NET 8 Web App support only the **Start from Blank App** option.
