-# LuPPC
+# LuPI2
-Lua-based operating system, based on [LuPI2](https://github.com/Starchasers/LuPI2/), with a focus on PowerPC based Macintosh machines and an aim to support more OpenComputers-style components and mirror OpenComputers behavior more closely where practical.
+Second attempt at Lua based operating system, primarily aimed at RaspberryPi, but with ambition to support other boards as well. The main motivation is 
+fact that GNU/Linux + python solution isn't allays the best for people that haven't been programming ever, and Lua in one of the simplest, most 
+intuitive languages. It has only 6 types, very simple syntax, yet supports many advanced mechanisms.

 1. Clone this repository

 3. Get `xxd` utility (usually packaged with vim)
 4. Build dependencies using scripts/dependencies.sh script for your platform(s)
 5. Execute `make build`
-6. You will need to put some OS to `root` directory where you run the binary. For now you can get PsychOS2 from the [PsychOS build server](https://oc.shadowkat.net/psychos/psychos.cpio)
