+MQTT is a lightweight messaging protocol that is ideal for sending small packets of data to and from IoT devices via WiFi. You will need to get the mqtt library file from our [Pycom libraries](https://github.com/pycom/pycom-libraries/tree/master/lib) repository on GitHub and place it in the `lib` folder of your project. 
 
 The broker used in this example is the [IO Adafruit](https://io.adafruit.com) platform, which is free and allows for tinkering with MQTT.
 
 Visit [IO Adafruit](https://io.adafruit.com) and create an account. You'll need to get hold of an API Key as well as your credentials. Visit this [guide](https://learn.adafruit.com/adafruit-io/mqtt-api) for more information about MQTT and how to use it with Adafruit's Broker.
 
 This example will send a message to a topic on the Adafruit MQTT broker and then also subscribe to the same topic, in order to show how to use the subscribe functionality.
 
+In the Pybytes library, we use mqtt as well. If you want to use a separate mqtt connection in conjunction with Pybytes, you will need to rename the `class MQTTCLient:` in the `mqtt.py` file to (for example) `class MQTTClient_lib:`, and import using the commented statement to avoid a naming conflict.

 ```python
 from mqtt import MQTTClient
+# from mqtt import MQTTClient_lib as MQTTClient
 from network import WLAN
 import machine
 import time
