Register Amazon Alexa

First you need to obtain a set of credentials from Amazon to use the Alexa Voice service. Make a note of these credentials as you will be asked for them during the install process.

Login at https://developer.amazon.com and go to ALEXA, then Alexa Voice Service.
Register a Product Type > Device.
For the Device Type ID and Display Name use something like AlexaPi or whatever you want.
You are at Security Profile left tab.
From the drop-down menu choose Create a new profile.
Choose whatever for Security Profile Name and Security Profile Description. Hit Next.
Under Web Settings horizontal tab hit Edit and:
Allowed Origins - put there https://localhost:3000 and http://ALEXA.DEVICE.IP.ADDRESS:3000
Allowed Return URLs put https://localhost:3000/authresponse and http://ALEXA.DEVICE.IP.ADDRESS:3000/authresponse. You have to replace ALEXA.DEVICE.IP.ADDRESS with the IP (for example 192.168.1.123) of your AlexaPi device (for example Raspberry Pi). This is especially necessary when you are installing from another computer than AlexaPi is gonna run on.
