The Orion SDK can now be installed through the Chocolatey package manager. "Chocolatey NuGet is a Machine Package Manager, somewhat like apt-get, but built with Windows in mind." To download and install the Orion SDK using this method, just run "choco install orionsdk". When we post new versions of the Orion SDK, "choco update all" will upgrade you.
This does not replace the way we normally distribute the SDK - it is just there for your convenience.
