Including a package provider in a command can make dynamic parameters available to a cmdlet. Dynamic parameters are specific to a package provider. The Get-Help cmdlet lists a cmdlet's parameter sets and includes the provider's parameter set. For example, Get-Package has the PowerShellGet parameter set that includes -NoPathUpdate, AllowClobber, and SkipPublisherCheck.
