 # lucicOS

 lucicOS is an educational, UNIX-like operating system built from scratch using
 the following resources:
   * [OSdev](https://wiki.osdev.org/Expanded_Main_Page)
   * [Little OS Book](https://littleosbook.github.io/)
   * [JamesM kernel development tutorial](http://www.jamesmolloy.co.uk/tutorial_html/)
-  * [OS from 0 to 1](https://github.com/tuhdo/os01)
+  * [Intel manuals](http://web.eecs.umich.edu/~farnam/482/Winter99/intarch.html)
+  * [BrokenThron](http://www.brokenthorn.com/Resources/OSDevIndex.html)
+
+At the moment it is not aimed to be portable or support multiple architectures.
+It is just my attempt to learn some important concepts about operating systems
+and develop my coding techniques.
+
+It only supports x86 architecture.
+
+## Building the project
 
 It can be built using the following command: `./build.sh`. To run the OS in
 bochs, just run `./bochs.sh`, the same applies to qemu, just run `./qemu.sh`.
 
+For building, running and testing, I use the following tools:
+  * i686-elf-gcc (GCC) 8.2.0
+  * GNU ld (GNU Binutils) 2.31.1
+  * GNU ar (GNU Binutils) 2.31.1
+  * QEMU emulator version 2.11.
+  * Bochs ??

+## Features
+
 At this moment there is still a lot of work to do in order to call this a real
-Operating System. It has some modules for writing to VGA, for writing to
-a serial port and it has support for entering in protected mode.
+Operating System. 
+These are some features that I managed to understand and implement:
+    * VGA (writing on screen)
+    * Serial (writing on serial ports)
+    * Keyboard (reading characters/shortcuts from keyboard)
+    * Timer (Receiving data from Programmable Interval Timer)
+    * Physical and Virtual Memory Mangers
+    * Interrupt request and Interrupt Service Routines
+    * Global Descriptor Table and Protected Mode
+
+What I am currently working at:
+    * Moving the kernel in the Higher Half
+    * Writing a consistent Page Allocator
+    * Making a tutorial out of this project

+## Notes
 
 The only supported architecture is x86 because it has the richest documentation
 and all the tutorials on the internet are x86 oriented.
