 .SYNOPSIS
-
 New-DscResourcePowerShellHelp generates PowerShell compatible help files for a DSC
 resource module
 
 .DESCRIPTION
-
 The New-DscResourcePowerShellHelp cmdlet will review all of the MOF based resources
-in a specified module directory and will inject PowerShell help files for each resource
-in to the resource's subdirectory. These help files include details on the property types for
-each resource, as well as a text description and examples where they exist.
-a README.md with a text description must exist in the resource's subdirectory for the
+in a specified module directory and will inject PowerShell help files for each resource.
+These help files include details on the property types for each resource, as well as a text
+description and examples where they exist.
+
+The help files are output to the OutputPath directory if specified, or if not, they are
+output to the releveant resource's 'en-US' directory.
+
+A README.md with a text description must exist in the resource's subdirectory for the
 help file to be generated.
+
 These help files can then be read by passing the name of the resource as a parameter to Get-Help.
 
 .PARAMETER ModulePath
-
 The path to the root of the DSC resource module (where the PSD1 file is found, not the folder for
 each individual DSC resource)

 This example shows how to generate help for a specific module
