 ## About
 Kern is a 32-bit OS based on the x86 architecture written in NASM Assembly and C. 
+I'm working on a basic command line as well as a custom filesystem (filetable for now).
 
-It supports a basic command line and has a custom filesystem.
+_Since 32-bit switch, a lot of features have been removed because they were dependent on BIOS interrupts_
-
-_Note: The filesystem is currently a basic filetable._
 
 ## Usage
 If you want to try kern for some reason, you can.

 For building, you'll need these tools:
 - [NASM](https://www.nasm.us/)
+- [GCC](https://gcc.gnu.org/) on linux
+- A cross compiler on mac (installation `$ brew tap nativeos/i386-elf-toolchain && brew install i386-elf-binutils i386-elf-gcc`)
 - [QEMU](https://www.qemu.org/) (for emulation)
 
+Then just run `./build.sh` and it should build and run qemu.
+
 I personally wouldn't recommend running this on real hardware, because it's untested and will just probably break you pc, but if you really want to, you can try it, but don't blame me if something goes wrong.
 
 If you don't know how to do something, try the 'help' command!
