+### Generating a Certificate Signing Request
 
 As mentioned, AWS IoT Core requires devices that connect to it using the MQTT protocol to use X.509 certificates for authentication. We'll use an example sketch from the `ArduinoECCX08` library to generate a Certificate Signing Request (CSR) from an Opta™ device and then upload this CSR in the AWS console to create an X.509 certificate.
 
 Open the `ECCX08CSR` example sketch by navigating to **File > Examples > ArduinoECCX08 > Tools**. To upload the code to your Opta™ device, click the **Verify** button to compile the sketch and check for errors; then click the **Upload** button to program the device with the sketch.

You will upload this file to the AWS console next.
