 ### Multiple-target probes
 
-mysql_exporter now support multi-target probes using the `/probe` route. To enable this feature, set `serviecMonitor.multipleTarget.enabled` to `true` and define your targets in `serviceMonitor.multipleTarget.targets`.
-Credentials for each target should be referenced in the associate config file. Target name should match the entry in the config file.
