+# Chroma
+The Chromatic OS
+
+## About
+Chroma is an x86_64 kernel, soon to be Operating System.  
+It uses the [bootboot](https://gitlab.com/bztsrc/bootboot) bootloader.
+
+## Features
+It can currently: 
+ - [x] read keyboard input
+ - [x] draw to the screen, including text and basic images.
+ - [x] output audio over the PC Speaker
+ - [x] manage physical memory
+ - [ ] manage virtual memory
+ - [ ] switch to ring 3
+ - [ ] switch tasks
+ - [ ] schedule tasks
+ - [ ] handle processes and threads
+ - [ ] handle mouse input
+ - [ ] display a basic 3D object
+ - [ ] display a basic 3D world
+ - [ ] display a basic 3D world *in VR*
+
+Once we reach this point... well, the world is our oyster.
+
+## Building
+
+Chroma can be built on Windows or Linux.
+
+### Windows
+I (Curle) use Windows for developing Chroma.  
+Simply have an [x86_64-elf-gcc](https://github.com/lordmilko/i686-elf-tools) and ld (included!) in your PATH, and run setup.bat.  
+You will need to use WSL to generate the iso; copy the created kernel.elf file to iso/boot/ as `initrd`, and run `grub-mkrescue -o chroma.iso iso/`.  
+A new system is in the works for creating this ISO natively on Windows.  
+
+The generated ISO works in QEMU, or on a physical test device (unlike a lot of other hobby OSes!)
+
+### Linux
+
+The system for linux is a lot easier, but you *do* need an x86_64-elf-gcc cross compiler. You can get one from the AUR on Arch-based distros (like Manjaro), or make one yourself using [the OSDev Wiki guide](https://wiki.osdev.org/GCC_Cross-Compiler)  
+Simply run the `init.sh` to generate a makefile, then `make` to create the kernel.elf file.  
+Same thing applies as Windows now - copy the kernel.elf file to iso/boot/ as `initrd` and run `grub-mkrescue -o chroma.iso iso/`.
