- 1. Install the app from the Play Store
- 2. Click on the option to install MultiROM's bootloader (and patched kernel if yours doesn't have kexec)
- 3. Once the app has taken care of that for you, click on the other option in it to install Ubuntu.
It's all pretty automatic, nearly zero user knowledge needed. And then you can test it out for yourself instead of doing something both scandalous and in this case useless anyways like RTFA'ing. But no, seriously, if you're curious at all, it really is quite easy to set up, and I do think worth it since you'll far more easily discover what Ubuntu Phone (and any other Linux-based smartphone platform you feel like tinkering with, or other Android ROMs) really is and how you do or don't like it.
