* Includes 2 vital details to make Alexa work
I spent several hours trying to figure out why this guide didn't work for me and it overlooked two very important things that must be done.
1. either forward 443 requests or change your serving port to 443
2. add "alexa:" to your configuration file. otherwise, the .../api/alexa?api_password=xxxxxxxxx will not exist.
* Minor changes
