Install Chocolatey with script directly from Chocolatey.Server. Script will determine if Chocolatey.nupkg is locally cached or not and provide a proper url for download. This script is meant to be used in the same way as it is done from https://chocolatey.org/install (the instructions are the same, the url is different).
