+# LuPI2
+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.
+
+Idea
+-----
+Design of system APIs is heavily influenced by [OpenComputers](https://github.com/MightyPirates/OpenComputers) minecraft mod. Some Lua code parts are 
+actually copied from there(all of the code is under the MIT License). Main advantage of the API is that it's event/component based, which provides great 
+level of abstraction. Custom components can be created and used with very little effort, being event-based simplifies code further, providing one unified 
+queue for events instead of multiple ways of handling them.
+```lua
+local component = require("component")
+
+--Create virtual LED component using built-in GPIO component
+local led = {}
+led.toggle = function() component.gpio.togglePin(27) end
+component.register(nil, "LED", led)
+
+--Blink the LED
+while true do
+  os.sleep(1)
+  component.led.toggle()
+end
+```
+
+Implementation
+-----
+On the low-level side LuPI will run on very stripped-down version of Linux kernel as init, it will be the only binary executable in system. Kernel will 
+only provide hardware drivers and abstract some of the things. Entire userspace is meant to be done using Lua. Security isn't the primary goal but still 
+needs to be considered.
