+# Toto OS
+Toto OS is a small operating system written in rust. This README will guide you through the process of building and running Toto OS.
+
+## Prerequisites
+Before building Toto OS, make sure you have th following installed on your machine:
+- rust (nightly)
+- cargo
+
+If you are interested in running Toto OS with the `make run` command, you will need to install QEMU.
+
+## Getting started
+To build Toto OS, follow these steps:
+
+1. Clone the repository.
+	 ```BASH
+	 git clone https://github.com/juls0730/toto-os.git
+	 cd toto-os
+	 ```
+2. Build Toto OS using `make` command:
+	 ```BASH
+	 make build
+	 ```
+
+You will be able to find the built image in `bin/os-image`.
+
+<br/>
+
+If you instead want to build Toto OS & run it with qemu, you can simply run make like so:
+```BASH
+make run
+```
