I am following this tutorial for connecting Raspberry Pi to AWS IoT using Node.js SDK and I have done all the other steps but I am lost in the authentication and certificate step:
pi@raspberrypi:~ $ aws iot describe-endpoint
You must specify a region. You can also configure your region by running "aws configure".
pi@raspberrypi:~ $ aws configure
AWS Access Key ID [None]: 
AWS Secret Access Key [None]: 
Default region name [None]: 
Default output format [None]: 
pi@raspberrypi:~ $ ls

When I browse to https://A34SXNTM6AT7XH.iot.us-west-2.amazonaws.com/things/MyNewThing/shadow or https://A34SXNTM6AT7XH.iot.us-west-2.amazonaws.com I see Missing Authentication Token message: 
I am not sure how to get the last step working so I could see stuff in the URLs when I browse to them. Can someone help me figure which steps I am missing or is missing from the tutorial?
