 Windows ships with a powerful scripting language called [PowerShell](https://en.wikipedia.org/wiki/Windows_PowerShell).
 
 Type in `powershell` in the search or run window in Windows. You may see two options - `PowerShell` and `PowerShell ISE`. The first is the regular PowerShell command prompt window. The second is the Interactive Scripting Environment. Feel free to choose either one. Here's [more](http://www.powershellpro.com/powershell-tutorial-introduction/tutorial-windows-powershell-console/) on getting started with PowerShell. Paste and run the following script and you're ready to go. This downloads Chocolatey, sets the environment path variable, and installs the exercism CLI.
