-## New Targets
+## New targets
 
 *   [.NET Core](https://www.dotnetfoundation.org/netcore): Has a modular design, employs side-by-side, and targets cross-platform scenarios. Side-by-side allows you to adopt new .NET Core versions without breaking other apps.
 *   [ASP.NET Core](https://www.dotnetfoundation.org/aspnet-core): is a modern web-framework built on .NET Core thus giving developers the same benefits.
 *   [.NET Native](https://blogs.msdn.microsoft.com/dotnet/2014/04/24/net-native-performance): Improve performance of your Windows Store apps that run on x64 and ARM machines by using .NET Native’s static compilation.

+## How to use Portability Analyzer
 
-To begin using the .NET Portability Analyzer, download the extension from the Visual Studio Gallery. You can configure it in Visual Studio via **Tools > Options > .NET Portability Analyzer** and select your Target Platforms. For now, use ASP.NET Core as a proxy for all .NET Core-based platforms (for example, [Windows 10 .NET UAP apps](http://blogs.windows.com/buildingapps/2015/03/02/a-first-look-at-the-windows-10-universal-app-platform/)).

 After running the analysis, you will see your .NET Portability Report. Only types that are unsupported by a target platform will appear in the list and you can review recommendations in the **Messages** tab in the **Error List**. You can also jump to problem areas directly from the **Messages** tab.
