+.PARAMETER ServerPath
+    The remote path on the Ubuntu server.
+    Default: /data/jingtian/BenjaminTeam
+    
+.PARAMETER LocalPath
+    The local BenjaminTeam folder path. If not specified, the script will
+    attempt to auto-detect or prompt the user.
+    
+.PARAMETER SyncInterval
+    Sync interval in minutes for the scheduled task.
+    Default: 5
+    
+.EXAMPLE
+    .\setup.ps1
