 A custom OS written in Rust
 
+## Running the OS
+
+You can start running the OS by executing:
+
+```bash
+cargo run
+```
+
+This assumes that you have a rust environment setup and cargo is available, the easiest way to do this is with [rustup](https://rustup.rs/).
+
+### Dependencies
+
+You should have the command `qemu-system-x86_64` available on your system to run the OS through an emulator, although it is also possible to flash it on an USB-drive and boot it directly.
+For debian users you can install the [`qemu-system-x86`](https://packages.debian.org/sid/qemu-system-x86) package and that will make sure all dependencies for the emulator are correctly installed.
+
+### Install to USB-drive
+
+To install it to an USB-drive you can use the following command if you are on a linux system.
+
+```bash
+sudo dd if=<path-to-project>/target/<config>/FerrOS of=/dev/sdX bs=1M status=progress
+```
