Instructions on how to install nuget provider in powershell

[DiegoSSJ]

When running the gulp task from a newly installed windows machine, it will complain that the nuget provider is not installed and apparently install it. But it doesn't really work. It looks like this:

[12:24:52] Starting 'install-packages'...
[12:24:52] Builder: Installing packages
Powershell - running: C:\websites\LiuSitecore\node_modules@pentia\sitecore-package-manager\powershell-scripts\Install-packages.ps1 -packagesFileLocation 'C:\website

Getting Sitecore.Full Package

The provider 'nuget v2.8.5.208' is not installed.
nuget may be manually downloaded from https://oneget.org/Microsoft.PackageManagement.NuGetProvider-2.8.5.208.dll and installed.
Would you like PackageManagement to automatically download and install 'nuget' now?

One needs to run
Register-PackageSource -Name "NuGet" -Location https://api.nuget.org/v3/index.json -ProviderName "NuGet"

To get the same question and make it work. Then one can remove the additionally added "NuGet" source and run the task again and it works.

This could be stated in the documentation as a help for new users.
