+## Welcome to the .NET Compiler Platform ("Roslyn")
+
+The .NET Compiler Platform ("Roslyn") provides open-source C# and Visual Basic compilers 
+with rich code analysis APIs.  It enables building code analysis tools with the same APIs 
+that are used by Visual Studio.
+
+### Try new language and IDE features
+
+Just want to provide feedback on new [language features](https://roslyn.codeplex.com/wikipage?title=Language%20feature%20status&referringTitle=Home) 
+and [IDE features](http://blogs.msdn.com/b/visualstudio/archive/2014/11/12/the-c-and-visual-basic-code-focused-ide-experience.aspx)? 
+
+* Try out [Visual Studio 2015 Preview](http://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs), 
+which has the latest features built-in.
+
+    Want to keep your box clean? You can use 
+[prebuilt Azure VM images](http://blogs.msdn.com/b/visualstudioalm/archive/2014/06/04/visual-studio-14-ctp-now-available-in-the-virtual-machine-azure-gallery.aspx) 
+with VS 2015 Preview already installed.
+
+* You can also try April's [End User Preview](http://go.microsoft.com/fwlink/?LinkId=394641), 
+which installs on top of Visual Studio 2013. *(Note: The VS 2013 preview is quite out of date, and is no longer being updated.)*
+
+### Build tools that understand C# and Visual Basic
+
+Get started building diagnostics, code fixes, refactorings, and other code-aware tools!
+
+1. Set up a box with Visual Studio 2015 Preview. Either 
+[install  Visual Studio 2015 Preview](http://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs), 
+or grab a [prebuilt Azure VM image](http://blogs.msdn.com/b/visualstudioalm/archive/2014/06/04/visual-studio-14-ctp-now-available-in-the-virtual-machine-azure-gallery.aspx).
+2. Install the [Visual Studio 2015 Preview SDK](http://www.visualstudio.com/en-us/downloads/visual-studio-2015-downloads-vs). 
+You'll need to do this even if you're using the Azure VM image. 
+3. Install the [SDK Templates VSIX package](http://visualstudiogallery.msdn.microsoft.com/849f3ab1-05cf-4682-b4af-ef995e2aa1a5) 
+to get the Visual Studio project templates. 
+4. Install the [Syntax Visualizer VSIX package](http://visualstudiogallery.msdn.microsoft.com/70e184da-9b3a-402f-b210-d62a898e2887) 
+to get a [Syntax Visualizer tool window](https://roslyn.codeplex.com/wikipage?title=Syntax%20Visualizer&referringTitle=Home) 
+to help explore the syntax trees you'll be analyzing.
+
+Or, you can grab the latest [NuGet Roslyn compiler package](http://www.nuget.org/packages/Microsoft.CodeAnalysis). 
+From the NuGet package manager console:
+
+    Install-Package Microsoft.CodeAnalysis -Pre
