+# Installing KIAUH
+
+In the following sections, you will be guided through the installation
+process step-by-step.
+
+To use KIAUH, it is enough to download the script and run it on your
+Raspberry Pi or other compatible device. If you need to know how to
+set up a Raspberry Pi or if you are unsure whether your current setup
+is sufficient, please refer to the [Raspberry Pi Installation Guide](raspberry-pi-setup.md)
+and follow the steps therein. Afterwards, you can return to this guide to install KIAUH.
+
+### Prerequisites
+Before you can download and run KIAUH, you need to ensure that ``git`` is
+installed on your system. Open a terminal and run the following command:
+
+```bash
+sudo apt-get update && sudo apt-get install git -y
+```
+
+### Downloading KIAUH
+After `git` was successfully installed, you can download KIAUH by
+cloning the repository from GitHub. It is recommended to clone it into
+your home directory. Run the following command in your terminal:
+```bash
+cd ~ && git clone https://github.com/dw-0/kiauh.git
+```
+
+### Running KIAUH
+Once the repository is cloned, you can start KIAUH. Make sure you are in
+your home directory and execute the script by running the following
+command:
+```bash
+./kiauh/kiauh.sh
+```
+
+After executing the command, you will be presented with the KIAUH menu,
+which allows you to install and manage various 3D printing software.
+For more information on how to use KIAUH, please refer to the
+[Usage Guide](usage.md).

+# Raspberry Pi Setup
+
+This guide will help you set up a Raspberry Pi for running Klipper and other,
+Klipper related 3D printing software. In case you are using a different single-board
+computer (SBC), please refer to the manufacturer's instructions for installing
+a compatible version of Linux on your device.
+
+It is assumed that you have at least a Raspberry Pi 3 or newer, along with a
+microSD card (at least 8GB, preferably 16GB or more) and a power supply.
+Additionally, you will need a computer with an SD card reader to prepare
+the microSD card.
+
+KIAUH requires a Linux operating system that has already been flashed to your
+Raspberry Pi's (or other SBC's) microSD card. As a result, you must ensure that you
+already have a functional Linux system on hand before you can proceed with
+installing KIAUH. `Raspberry Pi OS Lite` (either 32bit or 64bit) is a recommended Linux image
+if you are using a Raspberry Pi.
+
+---
+
+To flash `Raspberry Pi OS Lite` to your microSD card using the official [Raspberry Pi Imager](https://www.raspberrypi.com/software/),
+follow the steps below. If you encounter any issues or need further assistance, please refer to the [official Raspberry Pi documentation](https://www.raspberrypi.com/documentation/computers/getting-started.html).
+
+1. Open the Raspberry Pi Imager application on your computer.
+2. Click on `Choose OS` and select `Raspberry Pi OS (other)`.
+   ![OS selection](https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager1.png)
+3. Choose `Raspberry Pi OS Lite (32bit)` (or 64bit if desired).
+   ![Lite selection](https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager2.png)
+4. Insert the microSD card into your computer's SD card reader.
+5. In the main menu of the Imager, select the correct microSD card.
+6. Click the gear icon at the bottom left of the main menu to open advanced options.
+7. Enable SSH and enter your Wi-Fi credentials.
+
+    !!! info
+        Wi-Fi is only necessary if you want to connect to your Raspberry Pi over a wireless network. If you plan to use a wired Ethernet connection, you can skip this step. SSH is required for remote access to your Raspberry Pi, so make sure to enable it.
+
+8. Click `Save` to close the advanced options menu.
+9. Click `Write` to start flashing the image to the microSD card.
+
+    !!! warning
+        All data on the microSD card will be overwritten!
+
+10. Once the flashing process is complete, safely eject the microSD card from your computer.
+11. Insert the microSD card into your Raspberry Pi.
+12. Connect your Raspberry Pi to a power source to boot it up.
+13. Wait for a few minutes to allow the Raspberry Pi to complete its initial setup.
+14. You can now connect to your Raspberry Pi via SSH using the IP address assigned by your router. The default username is `pi` and the default password is `raspberry`.
+
+If you successfully connected to your Raspberry Pi via SSH, you can proceed to install KIAUH by following the instructions in the [Installation Guide](installation.md).
