 .SYNOPSIS
-Creates a local LIAM NTFS demo share structure with AGDLP groups and ACLs.
+Creates a local LIAM NTFS demo fixture with folders and ACL groups from a production log.
 
 .DESCRIPTION
-This script mirrors the LIAM NTFS demo configuration for the imagoverum.com
-environment:
+This script recreates the BRE.01.LEW/Projekte folder and ACL-group fixture from
+the diagnostic log in the local imagoverum.com demo environment:
 
 - local folder: C:\file_shares\share2
 - optional SMB share: \\<local-server>\file_shares\share2
@@ -12,6 +12,11 @@ environment:
 - group tags: FS for global groups, UG for domain-local groups
 - access tags: _O, _W, _R, _T
 
+By default the script creates the exact folders visible in the log and creates
+the logged ACL groups in the configured OU, then grants them Read permissions
+on the matching local folders. Expected LIAM groups can be created separately
+with -CreateExpectedLiamGroups.
+
 Run with -WhatIf first. The ActiveDirectory module is only required when
 AD group creation and ACL assignment are enabled.
