Can't figure out how to install it on my onn Google box

Hi. I got the onn Google box a few days ago and found the Channels DVR software but cannot figure out how to install it. It asked for an IP address but I don't know for what. It also mentioned my DVR server couldn't be found. What server? I thought this would be simple to get running and test out for it's recording capabilities, but I'm getting nowhere fast. I use Tivimate with so-so success and CosmiTV with nearly zero recording success. I hope you can help and that this app will solve my recording issues.
Thank you.

You'll need a server. Check out the docs
