+## MQTT support
+
+[MQTT](https://mqtt.org) is a lightweight, robust, publish-subscribe (pub-sub) protocol used in the IoT sector and elsewhere.
+It's very easy to use and makes it trivial to send data from one source system to any number of destination systems ("subscribers") that are interested in this particular data.
+
+Butler CW can be configured to send a MQTT message every time an app is cache warmed.  
+The configuration is done in the `mqttConfig` section of the main config file:
+
+```YAML
+# MQTT config parameters
+mqttConfig:
+  out: 
+    enable: true              # Should info about cache run/warming events be sent as MQTT messages?
+    baseTopic: butler-cw/     # Topic to send cache run events to. Should end with /
+    tzFormat: UTC             # LOCAL or UTC. Default is UTC
+  broker:                     # MQTT server/broker config
+    uri: mqtt://<MQTT server ip/FQDN>:<port>      ## Port is usually 1883
