 What is Proxmox Offline Mirror?
 -------------------------------
 
-With Proxmox Offline Mirror (POM) you can manage a local apt mirror for all Proxmox and Debian
-projects package updates. You can also export this mirror to a external medium to update systems
-that cannot connect to the repositories via HTTP, for example due to being completely air-gapped.
-Finally you can also manage subscription for such restricted hosts.
+With the Proxmox Offline Mirror tool, you can manage a local apt mirror for all package updates for
+Proxmox and Debian projects. From this local apt mirror you can create an external medium, for
+example a USB flash drive or a local network share, to update systems which cannot access the
+package repositories directly via the internet.  Such systems might be restricted by policies to
+access the public internet or are completely air-gapped.  Finally, you can also manage subscriptions
+for such restricted hosts.
