 ====== Development Software ======
 To build the software into an image that's usable on the hardware, a collection of scripts and other software is used to try and make the process as automated as possible.
+These can be found under the ''build-tools''.
+==== Needed Packages ====
+On Debian/Ubuntu: ''sudo apt-get install git qemu-system-arm''
+===== Emulation =====
+To remove the dependency on having a hardware Pi setup, QEMU is used to provide an emulated system.
+''qemu-system-arm'' must be installed on the system.
+The script ''start.sh'' takes the filename of the Raspberry Pi image to boot off. However, since there is no Raspberry Pi emulation available for QEMU, it relies on a kernel being specifically compiled for QEMU to use instead of the Raspberry Pi image kernel.
+''download_raspbian.sh'' can be run to get the latest release of Rasbian.
+===== Kernel =====
+This contains the scripts for building the kernel for use with QEMU, cd into the ''kernel'' directory and run ''./setup.sh build'', it will download the toolchain, kernel source, and build the kernel.
