+### Proxmox
+1. Download the script onto the desired host (the host must be added to LibreNMS devices)
+`wget https://github.com/librenms/librenms-agent/blob/master/agent-local/proxmox -o /usr/local/bin/proxmox`
+2. Make the script executable: `chmod +x /usr/local/proxmox`
+3. Edit your snmpd.conf file (usually `/etc/snmp/snmpd.conf`) and add:
+`extend proxmox /usr/local/bin/proxmox`
+(Note: if your snmpd doesn't run as root, you might have to invoke the script using sudo. `extend proxmox /usr/bin/sudo /usr/local/bin/proxmox`)
+4. Restart snmpd on your host
+5. On the device page in Librenms, edit your host and check `Proxmox` on the Applications tab.
