First you need to install it on your Smartv, see the links below:
The first step to use this app is to change your Smartv's DNS in the network settings.
Change the DNS assignment to manual and enter one of the addresses below:
DNS: 51.222.156.94
or

In the IP field, it is not necessary to make any changes.
