+## Scrip to update all containers
+(compatible with all)
 
+This script updates all running Proxmox containers, skipping specified excluded containers, and generates a separate log file for each container.
+The script first updates the Proxmox host system, then iterates through each container, updates the container, and reboots it if necessary.
+Each container's log file is stored in $log_path and the main script log file is named container-upgrade-main.log.
 
+### Install
+```
+wget https://github.com/Meliox/PVE-mods/blob/main/updateallcontainers.sh
+```
+Can be added to cron for e.g. monthly update: ```0 6 1 * * /root/scripts/updateallcontainers.sh```
