 ## Limitations/Known issues
 
+In version 0.1.14 of this module the alertmanager was configured to run as the service `alert_manager`. This has been changed in version 0.2.00 to be `alertmanager`.
+
 Do not use version 1.0.0 of Prometheus: https://groups.google.com/forum/#!topic/prometheus-developers/vuSIxxUDff8 ; it does break the compatibility with thus module!
 
 Even if the module has templates for several linux distributions, only RH family distributions were tested.
