+Description
+-----------
+
+This script is supposed to run from IPv6 DHCP client as lease script. On a
+DHCP leasse it runs each script containing the following line, where `##` is
+a decimal number for ordering:
+
+    # provides: dhcpv6-client-lease, order=##
+
+The lease script is started with some variables injected, but these are not
+available in child scripts. However this script makes these variables
+available with a global variable. This code is required in child script:
+
+    :global EitherOr;
+    
+    :global DHCPv6ClientLeaseVars;
+    
+    :local NaAddress [ $EitherOr $"na-address" ($DHCPv6ClientLeaseVars->"na-address") ];
+    :local NaValid [ $EitherOr $"na-valid" ($DHCPv6ClientLeaseVars->"na-valid") ];
+    :local PdPrefix [ $EitherOr $"pd-prefix" ($DHCPv6ClientLeaseVars->"pd-prefix") ];
+    :local PdValid [ $EitherOr $"pd-valid" ($DHCPv6ClientLeaseVars->"pd-valid") ];
+    :local Options [ $EitherOr $"options" ($DHCPv6ClientLeaseVars->"options") ];
+
+The values are available under different name then, use `$PdPrefix` instead
+of `$"pd-prefix"`, and so on. The resulting script supports both, being a
+lease script itself or being run as child.
+
+Currently it runs if available, in order:
+
+* [ipv6-update](ipv6-update.md)
+
+Requirements and installation
+-----------------------------
+
+Just install the script:
+
+    $ScriptInstallUpdate dhcpv6-client-lease;
+
+... and add it as `lease-script` to your dhcp client:
+
+    /ipv6/dhcp-client/set lease-script="dhcpv6-client-lease" [ find ];

 server. You can add more information to the comment, separated by comma. In
 this example the server is called `hotspot-to-wpa`.

 access-list. The default is four weeks.

-> ℹ️ **Info**: This script can not be used on its own but requires the base
-> installation. See [main README](../README.md) for details.
-
-Description
------------
-
-This script is supposed to run from dhcp server as lease script. On a dhcp
-lease it runs each script containing the following line, where `##` is a
-decimal number for ordering:
-
-    # provides: lease-script, order=##
-
-Currently it runs if available, in order:
-
-* [dhcp-to-dns](dhcp-to-dns.md)
-* [collect-wireless-mac](collect-wireless-mac.md)
-* [dhcp-lease-comment](dhcp-lease-comment.md)
-* `hotspot-to-wpa-cleanup`, which is an optional cleanup script
-  of [hotspot-to-wpa](hotspot-to-wpa.md)
-
-Requirements and installation
------------------------------
-
-Just install the script:
-
-    $ScriptInstallUpdate lease-script;
-
-... and add it as `lease-script` to your dhcp server:
-
-    /ip/dhcp-server/set lease-script=lease-script [ find ];
