-**iceOS** is a x86 monolithic kernel written in C from scratch.  
-This project doesn't aim to be a fully functional operating system
-with tons of drivers and graphical applications, it's just a learning tool to teach myself concepts like Operating Systems, Computer Architecture and Digital Electronics.
+**iceOS** is a x86 monolithic kernel written in C from scratch following the UNIX philosophy. This project is just a student learning tool to know more about operating systems, do not expect nothing more than a toy.

 ## Installation
 ### Requirements
-Before generating an ISO you have to compile a [cross compiler](https://wiki.osdev.org/GCC_Cross-Compiler) and you also have to install those packets:
+Before building this project you need to setup a [cross compiler](https://wiki.osdev.org/GCC_Cross-Compiler). Also install the following packages:  
 
 - nasm
 - bochs
 - grub
-- mtools(if you are on Arch Linux)
+- mtools(only for Arch Linux)
 
-Then you can run these commands:
+After that, you can build iceOS just by running the command listed below.  
 1. Type `make all` to compile the system and to create an ISO
 2. Type `make run` to start it in QEMU or `make bochs` to start it with bochs(only for debug purposes).
 
-Otherwise you can download an already compiled ISO file 
+You can also find a ISO file 
 [here](https://github.com/ice-bit/iceOS/raw/master/imgs/iceOS.iso)(md5sum: `342691301699a73102fa6a57abea6989`)

-- [x] Bare metal booting;
-- [x] VGA driver;
-- [x] Interrupts implementation;
-- [x] PIC & PIT implementation;
-- [x] PS/2 driver;
-- [x] Heap implementation;
-- [ ] Virtual File System
-- [x] Support for x86 architecture;
-- [x] GRUB as bootloader;
+iceOS has the following features:  
+- [x] VGA driver
