 # BlankOS
 
-Rewritten monolithic, ring 0, lower-half, singletasking kernel for the x86 processor architecture, using GRUB (eltorito) as bootloader. Emulation was tested on QEMU using Arch Linux 6.9.7-arch1-1, and on real hardware too.
+Rewritten monolithic, ring 0, lower-half, singletasking kernel for the x86 processor architecture, using GRUB 2 as bootloader. Emulation was tested on QEMU using Arch Linux 6.9.7-arch1-1, and on real hardware too.
 The long-term goal of this OS is to be capable of running user programs and having its own complete kernel C library so that users can write their own C programs and expand the system!
 
-## Features
-
-- Serial port driver (output & debug)
-- Framebuffer driver (output)
-- PS/2 Keyboard and PIC driver (input)
-- PIT (system clock/timer) driver
-- Working IDT, GDT, ISRs, and IRQs
-- Kernel panicking (exception handling)
-- A kernel-space shell
-- Cool color output!!
-- Some small working kernel-space programs, such as...
-- A brainfuck interpreter
-- An arithmetic calculator
-- ROT13 and Morse cipher programs
-- Conway's Game of Life
-- And some more...

 Replace `sdX` with your USB drive name (you can find it by doing `sudo fdisk -l`).
 Tada! You now have a working BlankOS USB stick. Go ahead and try it out!
 
-## Debugging (QEMU w/ GDB)

 ## Documentation
 
 Two other documents are available to help you understand the project better. One is the User's Manual, labelled [USERS.md](docs/USERS.md), and the other one is the Developer's Manual, labelled [DEVELOPERS.md](docs/DEVELOPERS.md). They are full of useful resources around Blank OS. You'll learn how to use the system and how to contribute to it. *(The docs might not always be up-to-date)*
