From the site:
Let’s get Chocolatey! Chocolatey NuGet is a Machine Package Manager, somewhat like apt-get, but built with Windows in mind. Easy Install! To install chocolatey now, open a command prompt and paste some text
To install simply paste the following into a command prompt:
@powershell -NoProfile -ExecutionPolicy unrestricted -Command “iex ((new-object net.webclient).DownloadString(‘http://bit.ly/psChocInstall’))” && SET PATH=%PATH%;%systemdrive%\chocolatey\bin
Don’t feel comfortable running commands you found on some random blog? I don’t blame you. Head over to their site to learn more about Chocolatey NuGet.
