 To send device-to-cloud telemetry messages using routes:
 
-* Use ModuleClient of the [Azure IoT SDK](https://github.com/Azure/azure-iot-sdks). Each module has *input* and *output* endpoints. 
-* Use the `ModuleClient.sendMessageAsync` method (or equivalent in your preferred language) to send messages on the output endpoint of your module. 
-* Configure a route in edgeHub to send this output endpoint to IoT Hub.
+* Use the Module Client class of the [Azure IoT SDK](https://github.com/Azure/azure-iot-sdks). Each module has *input* and *output* endpoints. 
+* Use a send message method from your Module Client class to send messages on the output endpoint of your module. 
+* Set up a route in the edgeHub module of your device to send this output endpoint to IoT Hub.
 
 To process messages using routes:
 
 * Set up a route to send messages coming from another endpoint (module or device) to the input endpoint of your module.
 * Listen for messages on the input endpoint of your module. Each time a new message comes back, a callback function is triggered by the Azure IoT SDK. 
 * Process your message with this callback function and (optionally) send new messages in your module endpoint queue.

 #### Twins
 
 Twins are one of the primitives provided by IoT Hub. There are JSON documents that store state information including metadata, configurations, and conditions. Each module or device has its own twin.
