+# MQTT -- An API for using MQTT over multiple transports
+
+This library originated from https://os.mbed.com/teams/mqtt/code/MQTT/ but has been modified to allow you to select different transports by
+modifing the mbed_app.json file. 
+
+## Specifying the connectivity method
+
+Add the following to your `mbed_app.json` file:
+
+```json
+{
+    "config": {
+        "mqtt-interface":{
+            "help": "options are MQTT_ETHERNET, MQTT_WNC14A2A, MQTT_BG96"
+            "value": "MQTT_ETHERNET"
+        }
+    }
+}
+```
