+  The minimum requirement for developing Angular 2 applications with Visual Studio is Update 3.
+  Earlier versions do not follow the best practices for developing applications with TypeScript.
+  To view your version of Visual Studio 2015, go to `Help | About Visual Studio`.
+  
+  If you don't have it, install **[Visual Studio 2015 Update 3](https://www.visualstudio.com/en-us/news/releasenotes/vs2015-update3-vs)**.
+  Or use `Tools | Extensions and Updates` to update to Update 3 directly from Visual Studio 2015.

+h2#prereq3 Prerequisite: Configure External Web tools
 :marked
-  Ensure you have the latest version of Visual Studio 2015 installed. 
-  Then open Visual Studio and install the latest set of TypeScript tools as follows:
+  Configure Visual Studio to use the global external web tools instead of the tools that ship with Visual Studio:
 
-  * Open `Tools` | `Extensions and Updates`.
-  * Select `Online` in the tree on the left.
-  * Search for `TypeScript` using the search box in the upper right.
-  * Select the most current available TypeScript version.
-  * Download and install the package.
+    * Open the **Options** dialog with `Tools` | `Options`
+    * In the tree on the left, select `Projects and Solutions` | `External Web Tools`.
+    * On the right, move the `$(PATH)` entry above the `$(DevEnvDir`) entries. This tells Visual Studio to
+      use the external tools (such as npm) found in the global path before using its own version of the external tools.
+    * Click OK to close the dialog.
+    * Restart Visual Studio for this change to take effect.
+
+  Visual Studio will now look first for external tools in the current workspace and 
+  if not found then look in the global path and if it is not found there, Visual Studio
+  will use its own versions of the tools.

+h2#prereq4 Prerequisite: Install TypeScript 2 for Visual Studio 2015
+:marked
+  While Visual Studio Update 3 ships with TypeScript support out of the box, it currently doesn’t ship with TypeScript 2, 
+  which you need to develop Angular 2 applications.
+
+  To install TypeScript 2:
+   * Download and install **[TypeScript 2.0 for Visual Studio 2015](http://download.microsoft.com/download/6/D/8/6D8381B0-03C1-4BD2-AE65-30FF0A4C62DA/TS2.0.3-TS-release20-nightly-20160921.1/TypeScript_Dev14Full.exe)**
+   * OR install it with npm: `npm install -g [email protected]`.
+
+  You can find out more about TypeScript 2 support in Visual studio **[here](https://blogs.msdn.microsoft.com/typescript/2016/09/22/announcing-typescript-2-0/)**
+
+  At this point, Visual Studio is ready. It’s a good idea to close Visual Studio and 
+  restart it to make sure everything is clean.
