Proxmox "Virtual Environment" (VE) is a Debian-based platform for running and managing virtual appliances, containers and virtual machines. The latest version of the distribution, Proxmox 4.3 "Virtual Environment", includes a number of upgrades to the project's documentation and improvements to the graphical interface. "The new reference documentation is created like the former Proxmox technical documentation: man pages are auto-generated based on the code, help content itself is written by the developers via comments in the code. Then for generating the docu the Proxmox VE project uses asciiDoc. To participate in the documentation project users can send a patch to the open source project for proposing new content. The former documentation, the Proxmox VE wiki, stays public, links to the reference documentation, and hosts all the how-tos, use cases, etc. The updated vertical GUI structure is one of the main advancements made to the GUI of Proxmox VE 4.3. Proxmox developers re-arranged some of the horizontal menus in the GUI framework Sencha ext JS 6 introduced with Proxmox version 4.2 and they are now vertical."
