+# Set up your machine to use the latest FluentUI-Blazor package
+
+These instructions will get you set up with the latest build of **FluentUI-Blazor**.
+
+Each time a commit is pushed into the `main` ou `dev`, the **Core** package is published on a special NuGet repository.
+Install the latest [Visual Studio 2022 Preview version](https://visualstudio.microsoft.com/vs/preview/) for the tooling.
+
+**This package is a preliminary version and are not intended for production use.
+It is intended to be used to test the latest feature and bug fix.** 
+
+If you just want the last final release of **FluentUI-Blazor**, the packages are on [NuGet.org](https://www.nuget.org/packages/Microsoft.FluentUI.AspNetCore.Components).
+
+## Add necessary NuGet feed
+
+The latest builds are pushed to a special feed, which you need to add:
+```sh
+dotnet nuget add source --name dotnet8 https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet8/nuget/v3/index.json
+```
+
+As usual this will add the feed to any existing NuGet.config in the directory or above,
+or else in the global NuGet.config. See [configuring NuGet behavior](https://learn.microsoft.com/en-us/nuget/consume-packages/configuring-nuget-behavior) to read more about that.
+
+Alternatively, if you are using Visual Studio, you can [Install and manage packages in Visual Studio](https://learn.microsoft.com/nuget/consume-packages/install-use-packages-visual-studio#package-sources)
+and add the feed `https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet8/nuget/v3/index.json` there.
+
+## Documentation
+
+The documentation for this preliminary version is available at [https://preview.fluentui-blazor.net/](https://preview.fluentui-blazor.net/).
