Chocolatey is a machine-level package manager and installer for software packages, built for the Windows NT platform.
It is an execution engine using the NuGet packaging infrastructure and Windows PowerShell to provide an automation tool for installing software on Windows machines, designed to simplify the process from the user perspective.
The name is an extension on a pun of NuGet (from "nougat") "because everyone loves Chocolatey nougat".
