+## KDMqtt
+
+KDMqtt provides a cross-platform MQTT client solution, based on [mosquitto](https://mosquitto.org/).
+
+You get a thin wrapper around libmosquitto that
+
+* seamlessly integrates into KDFoundation's `CoreAppliation`
+* comes with an API featuring properties and signals using [KDBindings](https://github.com/KDAB/KDBindings)
+
+For now, we don't support building mosquitto from source so you need to have it installed on your machine.
+
+You can find setup instructions and download links at
+
+<https://mosquitto.org/download/>
