-       -Prefix 'Mam' `
-       -Author 'Jane Doe' `
-       -Description 'Does awesome things' `
-       -ProjectUri 'https://github.com/janedoe/MyAwesomeModule'

+       ModuleName  = 'MyAwesomeModule'
+       Prefix      = 'Mam'
+       Author      = 'Jane Doe'
+       Description = 'Does awesome things'
+       ProjectUri  = 'https://github.com/janedoe/MyAwesomeModule'
+   }
+   ./Initialize-Template.ps1 @templateParameters
    ```
