 # Citrix Optimizer Automation
+
+PowerShell module to automate the creation of Citrix Optimizer Templates using simple pre-build cmdlets such as:
+
+* New-CitrixTemplate
+* New-CitrixTemplateGroup
+* New-CitrixTemplateRegistry
+* New-CitrixTemplateService
+* New-CitrixTemplateTask
+
+The reason behind creating this module is the time is takes to build up the template files using the user interface. Often customers have various CSV files and JSON files with the settings you want applied to a master image, with this module you are able to parse those files and inject the settings automatically.
