 ## How Can I Contribute?

 If you want to contribute a new feature of fix a bug you can open a pull request. 
 
 Make sure you follow this procedure:
-
+* **Important!!!** if you itent to make a lot of changes in a pull request open an issue to discuss this with us first. The Radzen Blazor Components have a lot of
+moving parts and making big changes should be done with extra precautions. 
 * **Be sure that none of the existing tests** breaks after your changes. The test project is available [here](https://github.com/radzenhq/radzen-blazor/tree/master/Radzen.Blazor.Tests).
 * **If possible add new tests that verify your fix or new feature**. 
 * **Follow the existing coding style** (to be described in detail later).

+![Radzen Blazor Components](https://raw.githubusercontent.com/radzenhq/radzen-blazor/master/RadzenBlazorDemos/wwwroot/images/radzen-blazor-components.png)
+
+## Why choose Radzen Blazor Components?
+
+### :sparkles: Free
+
+Radzen Blazor Components are open source and free for commercial use. You can install them from [nuget](https://www.nuget.org/packages/Radzen.Blazor) or build your own copy from source.
+
+Paid support is available as part of the [Radzen Professional subscription](https://www.radzen.com/blazor-studio/pricing/).
+
+### :computer: Native
+
+The components are implemented in C# and take full advantage of the Blazor framework. They do not depend on or wrap existing JavaScript frameworks or libraries.
+
+Blazor Server and Blazor WebAssembly are fully supported.
+
+### :seedling: Growing
+
+We add new components and features on a regular basis.
+
+Short development cycle. We release as soon as new stuff is available. No more quarterly releases.
+

+
+### :dart: Dedicated Support
+
+The Radzen team monitors the forum threads, but does not guarantee a response to every question. For guaranteed responses you may consider the dedicated support option.
+
+Dedicated support for the Radzen Blazor Components is available as part of the [Radzen Professional subscription](https://www.radzen.com/blazor-studio/pricing/).
+
+Our flagship product [Radzen Blazor Studio](https://www.radzen.com/blazor-studio/) provides tons of productivity features for Blazor developers:
+- An industry-leading WYSIWYG Blazor design time canvas
+- Scaffolding a complete CRUD applications from a database
+- Built-in security - authentication and authorization
+- Visual Studio Code and Professional support
+- Deployment to IIS and Azure
+- Dedicated support with 24 hour guaranteed response time
+
+## Get started with Radzen Blazor Components
+
+### 1. Install
+
+Radzen Blazor Components are distributed as a [Radzen.Blazor nuget package](https://www.nuget.org/packages/Radzen.Blazor). You can add them to your project in one of the following ways
+- Install the package from command line by running `dotnet add package Radzen.Blazor`
+- Add the project from the Visual Nuget Package Manager
+- Manually edit the .csproj file and add a project reference
+
+### 2. Import the namespace
+
+Open the `_Imports.razor` file of your Blazor application and add this line `@using Radzen.Blazor`.
+
+### 3. Include a theme
+Radzen Blazor components come with five free themes: Material, Standard, Default, Dark, Software and Humanistic.
+
+To use a theme
+1. Pick a theme. The [online demos](https://blazor.radzen.com/colors) allow you to preview the available options via the theme dropdown located in the header. The Material theme is currently selected by default.
+1. Include the theme CSS file in your Blazor application. Open `Pages\_Layout.cshtml` (Blazor Server .NET 6), `Pages\_Host.cshtml` (Blazor Server .NET 7) or `wwwroot/index.html` (Blazor WebAssembly) and include a theme CSS file by adding this snippet
+   ```html
+   <link rel="stylesheet" href="_content/Radzen.Blazor/css/material-base.css">
+   ```
+
+To include a different theme (i.e. Standard) just change the name of the CSS file:
+```
+<link rel="stylesheet" href="_content/Radzen.Blazor/css/standard-base.css">
+```
+
+### 4. Include Radzen.Blazor.js
+
+Open `Pages\_Layout.cshtml` (Blazor Server .NET 6), `Pages\_Host.cshtml` (Blazor Server .NET 7) or `wwwroot/index.html` (Blazor WebAssembly) and include this snippet:
+
+```html
+<script src="_content/Radzen.Blazor/Radzen.Blazor.js"></script>
+```
+
+### 5. Use a component
+Use any Radzen Blazor component by typing its tag name in a Blazor page e.g.
+```html
+<RadzenButton Text="Hi"></RadzenButton>
+```
+
+#### Data-binding a property
+```razor
+<RadzenButton Text=@text />
+<RadzenTextBox @bind-Value=@text />
+@code {
+  string text = "Hi";
+}
+```
+
+#### Handing events
+
+```razor
+<RadzenButton Click="@ButtonClicked" Text="Hi"></RadzenButton>
+@code {
+  void ButtonClicked()
+  {
+
+  }
+}
+```
