 - debug: attaches gdb to an instance of QEMU running REDACTED OS. The instance must be run with the `debug` argument as `./run debug` in order for gdb to attach and control its execution. It can support automatically running a command inside gdb such as adding a breakpoint by passing it as an argument as `./debug b kernel_main`
 - rundebug: a shortcut for running both the `run` and `debug` commands. It can pass arguments for the debug command, which in turn will pass them to gdb
 - createfs: creates a filesystem image for the system to read. The image does not contain kernel code and is not used to boot the system, but is still required to boot the system, and contains user processes. The script is written specifically for macOS, as it relies on the diskutil commands to create the image. There isn't a linux or windows version for it, but a filesystem image can be created manually and placed in the root directory with the name disk.img
-- Makefile: can compile and run the system. `make run` compiles the system, creates the filesystem image and executes the `./run` command. `make debug` compiles the system, creates the filesystem and executes the OS and gdb, through the `./rundebug` command. `make all` simply compiles and creates the filesystem image. `make clean` cleans compiled files.
+- Makefile: can compile and run the system. `make run` compiles the system for the virt board, passing MODE=virt/raspi specifies which board to compile for.
