# WeCom Center — one-step installer for a new Zabbix frontend
#
# Usage:
#   ./install.sh                 # auto-detect a running zabbix-* web container
#   ./install.sh /path/to/modules# copy into a plain (non-docker) modules dir
#
# After this script finishes, open Zabbix -> Administration -> Modules,
# press "Scan directory", then Enable "WecomCenter". Then open the
# WeCom Center page and use the "First-time setup / Initialise" button.
