+## What is the purpose of this template:
+
+This template will automatically detect and supervise the temperature sensors of the machines.
+
+It's optimized to make only one request on the agent, and to proceed the data on the Zabbix server
+
+## How to setup:
+
+### On your servers :
+
+Make sure to install lm-sensors >= 3.5.0 and run the command `sensors-detect`
+
+copy the `userparameter_sensors.conf` file in the directory "/etc/zabbix/zabbix_agentd.d/" and restart your zabbix agent
