Scoop is a command line installer for Windows. It is aimed at *nix developers who are disillusioned by other offerings. It doesn't require administrator access, and it avoids polluting your $PATH.
I am one of two main contributors and I have been using it for several years. It works in Windows 7+ and requires at least Powershell 3 (you should have it if you install Windows Updates)
How is Scoop different to Chocolately?
Installation
