+.SYNOPSIS
+    PowerShell script for managing Windows static routes
+
+.DESCRIPTION
+    This script is used to add or remove static route entries in Windows systems.
+    It supports using full subnet mask (Mask) or subnet mask length (MaskLen) to specify the mask.
+    The script will automatically request administrator privileges to modify the system routing table.
+
+.PARAMETER Add
+    Used to add a new route record
+
+.PARAMETER Remove
+    Used to remove an existing route record
+
+.PARAMETER Target
+    Destination network address
+
+.PARAMETER Mask
+    Full format subnet mask (e.g.: 255.255.255.0)
+
+.PARAMETER MaskLen
+    Subnet mask length (e.g.: 24 represents 255.255.255.0)
+
+.PARAMETER Gateway
+    Gateway address
+
+.EXAMPLE
+    RouteManager.ps1 -Add -Target 192.168.12.0 -Mask 255.255.255.0 -Gateway 192.168.31.9
+    
+.EXAMPLE
+    RouteManager.ps1 -Add -Target 192.168.12.0 -MaskLen 24 -Gateway 192.168.31.9
+    
+.EXAMPLE
+    RouteManager.ps1 -Remove -Target 192.168.12.0 -Mask 255.255.255.0 -Gateway 192.168.31.9
