At the time of writing, the ROM is an unofficial build and is in the testing phase, so you might occasionally come across a few bugs and issues. Moreover, as of now, the ROM has included GApps for testing [so you may skip Step 10 for now]. Once it moves over to the official build, it will only be a Vanilla build. So keep these points in mind while flashing it.
