+### Building (Debian)
  - Clone the repository.
  - Ensure you have the `gcc-arm-none-eabi` cross compiler installed `# apt install gcc-arm-none-eabi`.
  - From the root of the directory, i.e. in `Jobbed`, execute `make -f Unix.mk`
  - The built image is found in `build/kernel7.img` and can be copied to the root of the Raspberry Pi SD card's first parition

+### Running
  - Ensure you have QEMU's ARM package installed on your system
  - Minimum command line arguments to run: `qemu-system-arm -M raspi2b -cpu cortex-a7 -m 1G -kernel build/kernel.elf`
  - When building `build/kernel7.img`, `build/kernel.elf` will also be built and is used to emulate the Raspberry Pi 2B

+## Building RTOS Applications
 RTOS Applications are written in the `usr/` directory.
 Jobbed, in `kernel/core.c` adds in the `main` function at the highest priority, expected to be defined in `usr/main.c`.
 This `main` function, can serve as the initialization function for the RTOS application.

 This testing suite outputs the tracing, thread switch, low and high priority thread creation, mutex creation, mutex destruction, mutex locking contention, mutex locking non-contention, mutex unlocking, semaphore waiting, semaphore signalling at zero, semaphore signalling non-zero timings to a 1920x1080 display output.
 Currently the graphics driver expects this resolution of display. If you have another resolution, this can be changed in `kernel/graphics/lfb.c` by modifying `SCR_WIDTH` and `SCR_HEIGHT`.
