+AnotterKiosk
 =============================
 
-### I have hacked this about alot from the main branch, mainly Raspberry Pi changes
- - Removed the RO filesystem
- - Added scheduled screen on/off
- - Added scheduled chrome page refresh
- - Rpi3 Overclock settings
- - Disabled KMS driver for HW screen rotation (screen rotated portrait by default)
-
 ### Overview
 Another kiosk browser OS? Yes, this one is a little bit opinionated :)
