 the V2 menu:
 
     tapm V2
+
+To change the TA-ProxMenu `origin` URL on every installed node in the current
+Proxmox cluster, either select `G` in the legacy menu or run:
+
+    tapm git-url
+
+The command prompts for the new repository URL, discovers cluster nodes with
+`pvecm`, verifies that each node can read the new repository's `main` branch,
+and only then changes that node's `origin`. A URL can also be supplied:
+
+    tapm git-url https://git.example.com/organization/TA-ProxMenu.git
+
+Add `--yes` as the third argument for a non-interactive confirmation:
+
+    tapm git-url https://git.example.com/organization/TA-ProxMenu.git --yes
+
+Private repositories require read credentials to be configured on every node
+before migration. Repository credentials must not be embedded in the URL.
