+1. Install the rust nightly toolchain for `armv7a-none-eabihf`:
+```shell
+rustup target add armv7a-none-eabihf --toolchain nightly
+rustup +nightly component add rust-src
+```
+
+Unfurtuantly `armv7a-none-eabihf` is a [tier3](https://doc.rust-lang.org/nightly/rustc/platform-support.html#tier-3) target for the Rust compiler so building for it requires the nightly toolchain - [source](https://stackoverflow.com/questions/67352828/how-to-build-for-tier-3-target-not-included-in-rustup-target-list)
+
+> **Notice** Verify that you install the `armv7a-none-eabihf` target and not the `armv7a-none-eabi` target, as the later doesn't have support for hardware floats.
+
+2. Install Cargo Binutils:
+```shell
+cargo install cargo-binutils
+rustup component add llvm-tools-preview
+```
+
+3. Edit the relevant settings in `configuration.rs`
+4. Run `build.sh` or `build.bat` which will compile and create an bootable image called `kernel7.img`

+### Raspberry Pi Baremetal
+
+Currently only Raspberry Pi 4 is supported using the following instructions:
+* Format a sd card and make a single `FAT32` partition called `boot`
+* Copy the file `config.txt` to the root dir of the sd card
+* Copy the following files from the [Raspberry Pi firmware repo](https://github.com/raspberrypi/firmware/tree/master/boot) onto the SD card:
+    - [fixup4.dat](https://github.com/raspberrypi/firmware/raw/master/boot/fixup4.dat)
+    - [start4.elf](https://github.com/raspberrypi/firmware/raw/master/boot/start4.elf)
+    - [bcm2711-rpi-4-b.dtb](https://github.com/raspberrypi/firmware/raw/master/boot/bcm2711-rpi-4-b.dtb)
+* Copy `kernel7.img` onto the SD card
+* Connect all the peripherals (ili9341 display and gpio buttons)
+* Insert the SD card to the RPI4 and boot it
+
+_**Note**: Should it not work on your RPi4, try renaming `start4.elf` to `start.elf` (without the 4)
+on the SD card._
+
+### QEMU
+
+Currently Qemu doesn't support RPI4 in 32 bit mode, so in order to test it I added support for RPI2 mapping.
+To change to RPI2 mode build with the `rpi2` feature and not the default `rpi4` feature.
+
+running with qemu:
+```shell
+qemu-system-arm.exe -M raspi2b -serial null -serial mon:stdio -kernel path_to_elf
+```
+
+_**Note** Qemu takes the path to the elf generated by cargo not the image generated by binutils_
+the UART output will be written to the console.
+
+I think that not all the peripherals I use are implemented in QEMU so I used this mainly to debug boot and CPU initialization problems
