+## How to build and debug the Microsoft CppTools Extension  
+  
+These steps will allow you to debug the TypeScript code that is part of the Microsoft CppTools extension for Visual Studio Code.  
+  
+Prerequisite steps:  
+  * Clone [this](https://github.com/Microsoft/vscode-cpptools) repository.  
+  * Install [npm](https://nodejs.org).  
+  * From a command line, run the following commands from the **Extension** folder in the root of the repository:  
+      * `npm install -g vsce` will install `vsce` globally to create the vsix package.  
+      * `npm install` will install the dependencies needed to build the extension.  
+  * Set an environment variable `CPPTOOLS_DEV=1`.  
+    * This enables the local developer workflow, copying dependencies from the **node_modules** folder.  
+  * Open the **Extension** folder in Visual Studio Code and F5.  
+  * Read the [contributing guidelines](https://github.com/Microsoft/vscode-cpptools/blob/master/CONTRIBUTING.md).
