+===========================================================================
+
+.SYNOPSIS
+The purpose of the script is to create simple Toast Notifications in Windows 10
+
+.DESCRIPTION
+Toast_Notify.ps1 will read an XML file so Toast Notifications can be changed "on the fly" without having to repackage an application. The CustomMessage.xml file can be hosted on a fileshare.
+To create a custom XML, copy CustomMessage.xml and edit the text you want to disaply in the toast notification. The following files should be present in the Script Directory
+
+Toast_Notify.ps1
+BadgeImage.jpg
+HeroImage.jpg
+CustomMessage.xml
+
+.PARAMETER XMLScriptDirSource
+Specify the name of the XML file to read. The XML file must exist in the same directory as Toast_Notify.ps1. If no parameter is passed, it is assumed the XML file is called CustomMessage.xml.
+
+.PARAMETER XMLOtherSource
+Specify the location of the Custom XML file used for the Toast when it is not in the saem directory as the Toast_Notify.ps1 script
+
+.EXAMPLE
+Toast_Notify.ps1 -XMLOtherSource "\\fileserverhome\xml\CustomMessage.xml"
+
+.EXAMPLE
+Toast_Notify.ps1 -XMLSciptDirSource "CustomMessage5.xml"
