+**Notes**
+To build and test Visual F# IDE Tools, you must use [Visual Studio "vNext" (aka "Dev15")](https://www.visualstudio.com/en-us/downloads/visual-studio-next-downloads-vs.aspx). This is the one after Visual Studio 2015 (aka "Dev 14").  You must also install Visual Studio SDK (also called _Visual Studio Extensibility SDK_ on the Visual Studio installer) before building Visual F# IDE Tools.
+Please ensure that the Visual Studio SDK version is matched with your current Visual Studio to ensure successful builds. For example: Visual Studio 2015 Update 1 requires Visual Studio 2015 SDK Update 1. Any installation of Visual Studio 2015 and later provides Visual Studio SDK as part of the installation of Visual Studio 2015 as feature installation.
