When you run the cmdlet, Get-Help with another cmdlet as the argument, Get-Help fetches help information for the cmdlet that was passed as the argument; Get-Command in this case. We shall see in the later chapters how arguments are handled. For now, we're simply calling the help for an arbitrary cmdlet.

If you notice the output, you'd see the name of the cmdlet, the syntax to use with the cmdlet, the alias available for the cmdlet and more online help if required. Full and Examples are switches which tell PowerShell the level of help you need. These are mutually exclusive; you cannot run -Full and -Examples at the same time.
