 My attempt at making a bootloader and kernel.
 
+## How to use
+
+To compile, you need:
+
+- `i686-elf-gcc` for cross-compiling the kernel
+- A system `gcc` for compiling the host-helpers
+- `nasm` for compiling the bootloader
+- `qemu-system-i386` for emulating (`qemu-system-x86_64` will probably work too, but that is not directly supported)
+
+If you run `make bin`, it will generate `target/boot.bin`, this is a binary file layed out as described in [the docs](docs/bootloader.md). To burn it on a USB drive, simply `dd if=target/boot.bin of=/dev/sdb` and the drive is bootable and contains an SFS filesystem with the files in `filesystem/`.

 ## Bootloader
 
 The bootloader is self-written, based on articles on [the OSDev wiki](https://wiki.osdev.org/). It's a single stage, ELF-loading bootloader in the most basic way possible.
