Putting SmartTube on the device took about 15 minutes, most of that was finding a browser that would let me download a file without showing a million ads.

I just followed the instructions on the webpage, after installing the "Downloader" app from the Play Store. The hardest part was entering the SmartTube URL into Downloader using the on-screen keyboard and TV remote control. Kind of a pain, but totally worth it. After that, the SmartTube app can be updated inside the app easily.
