Your best bet will be to use PowerShell's "Get-Help" function to display the syntax for a given cmdlet. If you'd like to get all of the methods/properties associated with a cmdlet, you can run the cmdlet and then pipe it to Get-Member like this:
Get-NcCifsSessionFile | Get-Member
This will return all of the names, types, and definitions of the data collected by the cmdlet. As far as I know, this documentation only exists within the Toolkit itself and isn't documented elsewhere.
