+    .SYNOPSIS
+        Test-PSDCHyperVEnabled tests if Hyper-V is enabled
+
+    .DESCRIPTION
+        For the module to work properly the module needs Hyper-V to be enabled
+        The function tests is that's the case
+
+    .PARAMETER HostName
+        Hostname to check. The default is the current hostname
+
+    .PARAMETER EnableException
+        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
+        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
+        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
+
+    .PARAMETER WhatIf
+        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
+
+    .PARAMETER Confirm
+        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
