 Configuration
 -------------
 
-All configurations are stored in consul's KV with the prefix: `consul-alerts/config/`. The daemon is using default values and the KV entries will only override the defaults.
+To assure consistencty between instances all configurations are stored in consul's KV with the prefix: `consul-alerts/config/`. The daemon is using default values and the KV entries will only override the defaults. Configuration may be set manually through consul UI or API, using configuration management tools such as chef, puppet or Ansible, or backed up and restored using [consulate](https://github.com/gmr/consulate).  
+Example:  
+```
+consulate kv backup consul-alerts/config -f consul-alerts-config.json
+consulate kv restore consul-alerts/config -f consul-alerts-config.json --prune
+```
