+.Synopsis
+    Group Policy tools use administrative template files (.admx, .adml) to populate policy settings in the user interface.
+    This allows administrators to manage registry-based policy settings.
+    This script installs PSResourceGet Administrative Templates for Windows.
+.Notes
+    The PSResourceRepository.admx and PSResourceRepository.adml files are
+    expected to be at the location specified by the Path parameter with default value of the location of this script.
