-## **🛠️ Instructions:**
+<hr>
 
-For downloading this script it is necessary to have git installed.\
-If you haven't, please run `sudo apt-get install git -y` to install git first.\
-After git is installed, use the following commands in the given order to download and execute the script:
+<h2 align="center">
+  📄️ Instructions 📄

-```shell
-cd ~
+### 📋 Prerequisites
+KIAUH is a script that assists you in installing Klipper on a Linux operating system that has
+already been flashed to your Raspberry Pi's (or other SBC's) SD card. As a result, you must ensure
+that you have a functional Linux system on hand. `Raspberry Pi OS Lite (either 32bit or 64bit)` is a recommended Linux image
+if you are using a Raspberry Pi. The [official Raspberry Pi Imager](https://www.raspberrypi.com/software/)
+is the simplest way to flash an image like this to an SD card.
 
-git clone https://github.com/th33xitus/kiauh.git
+* Once you have downloaded, installed and launched the Raspberry Pi Imager,
+select `Choose OS -> Raspberry Pi OS (other)`: \
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager1.png" alt="KIAUH logo" height="350">
+</p>
 
-./kiauh/kiauh.sh
-```
+* Then select `Raspberry Pi OS Lite (32bit)` (or 64bit if you want to use that instead):
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager2.png" alt="KIAUH logo" height="350">
+</p>
+
+* Back in the Raspberry Pi Imager's main menu, select the corresponding SD card to which
+you want to flash the image.
+
+* Make sure to go into the Advanced Option (the cog icon in the lower left corner of the main menu)
+and enable SSH and configure Wi-Fi.
+
+* If you need more help for using the Raspberry Pi Imager, please visit the [official documentation](https://www.raspberrypi.com/documentation/computers/getting-started.html).
+
+These steps **only** apply if you are actually using a Raspberry Pi. In case you want
+to use a different SBC (like an Orange Pi or any other Pi derivates), please look up on how to get an appropriate Linux image flashed
+to the SD card before proceeding further (usually done with Balena Etcher in those cases). Also make sure that KIAUH will be able to run
+and operate on the Linux Distribution you are going to flash. You likely will have the most success with
+distributions based on Debian 11 Bullseye. Read the notes further down below in this document.
+
+### 💾 Download and use KIAUH
 **📢 Disclaimer: Usage of this script happens at your own risk!**
 
+* **Step 1:** \
+To download this script, it is necessary to have git installed. If you don't have git already installed, or if you are unsure, run the following command:
+```shell

+
+## 📄 使用说明
+
+### 📋 系统要求
+KIAUH 是一个帮助您在 Linux 系统上安装 Klipper 的脚本工具，
+它需要一个已经写入树莓派（或其他单板计算机）SD 卡的 Linux 系统。
+如果您使用树莓派，推荐使用 `Raspberry Pi OS Lite (32位或64位)` 系统镜像。
+[官方 Raspberry Pi Imager](https://www.raspberrypi.com/software/) 是将此类镜像写入 SD 卡的最简单方式。
+
+* 下载、安装并启动 Raspberry Pi Imager 后，
+选择 `Choose OS -> Raspberry Pi OS (other)`:
+
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager1.png" alt="KIAUH logo" height="350">
+</p>
+
+* 然后选择 `Raspberry Pi OS Lite (32位)` (或如果您想使用64位版本):
+
+<p align="center">
+  <img src="https://raw.githubusercontent.com/dw-0/kiauh/master/resources/screenshots/rpi_imager2.png" alt="KIAUH logo" height="350">
+</p>
+
+* 返回 Raspberry Pi Imager 主界面，选择对应的 SD 卡作为写入目标。
+
+* 确保点击左下角的齿轮图标（在主菜单中）
+启用 SSH 并配置 Wi-Fi。
+
+* 如果您需要更多关于使用 Raspberry Pi Imager 的帮助，请访问 [官方文档](https://www.raspberrypi.com/documentation/computers/getting-started.html)。

 This document covers possible important changes to KIAUH.
 
+### 2024-08-31 (v6.0.0-alpha.1)
+Long time no see, but here we are again!
+A lot has happened in the background, but now it is time to take it out into the wild.
+
+#### KIAUH has now reached version 6! Well, at least in an alpha state...
+
+The project has seen a complete rewrite of the script from scratch in Python.
+It requires Python 3.8 or newer to run. Because this update is still in an alpha state, bugs may or will occur.
+During startup, you will be asked if you want to start the new version 6 or the old version 5.
+As long as version 6 is in a pre-release state, version 5 will still be available. If there are any critical issues
+with the new version that were overlooked, you can always switch back to the old version.
+
+In case you selected not to get asked about which version to start (option 3 or 4 in the startup dialog) and you want to
+revert that decision, you will find a line called `version_to_launch=` within the `.kiauh.ini` file in your home directory.
+Just delete that line, save the file and restart KIAUH. KIAUH will then ask you again which version you want to start.
+
+Here is a list of the most important changes to KIAUH in regard to version 6:
+- The majority of features available in KIAUH v5 are still available; they just got migrated from Bash to Python.
+- It is now possible to add new/remove instances to/from existing multi-instance installations of Klipper and Moonraker
+- KIAUH now has an Extension-System. This allows contributors to add new installers to KIAUH without having to modify the main script.
+    - You will now find some of the features that were previously available in the Installer-Menu in the Extensions-Menu.
+    - The current extensions are:
+        - G-Code Shell Command (previously found in the Advanced-Menu)
+        - Mainsail Theme Installer (previously found in the Advanced-Menu)
+        - Klipper-Backup (new in v6!)
+        - Moonraker Telegram Bot (previously found in the Installer-Menu)
+        - PrettyGCode for Klipper (previously found in the Installer-Menu)
+        - Obico for Klipper (previously found in the Installer-Menu)
+    - The following additional extensions are planned, but not yet available:
+        - Spoolman (available in v5 in the Installer-Menu)
+        - OctoApp (available in v5 in the Installer-Menu)
+- KIAUH has its own config file now
+    - The file has some default values for the currently supported options
+    - There might be more options in the future
+    - It is located in KIAUH's root directory and is called `default.kiauh.cfg`
+        - DO NOT EDIT the default file directly, instead make a copy of it and call it `kiauh.cfg`
+        - Settings changed via the Advanced-Menu will be written to the `kiauh.cfg`
+- Support for OctoPrint was removed
+
+Feel free to give version 6 a try and report any bugs or issues you encounter! Every feedback is appreciated.
+
+### 2023-06-17
+KIAUH has now added support for installing Mobileraker's companion!
+Mobileraker is a free and Open Source Android and iOS App for Klipper, utilizing the Moonraker API, allowing you
+to control your printer. Thank you to [Clon1998](https://github.com/Clon1998) for adding this feature!
+
+### 2023-02-03
+The installer for MJPG-Streamer got replaced by crowsnest. It is an improved webcam service, utilizing ustreamer.
+Please have a look here for additional info about crowsnest and how to configure it: https://github.com/mainsail-crew/crowsnest \
+It's unsure if the previous MJPG-Streamer installer will be updated and make its way back into KIAUH.
+A big thanks to [KwadFan](https://github.com/KwadFan) for writing the crowsnest implementation.
+
+### 2022-10-31
+Some functions got updated, though not all of them.
+
+The following functions are still currently unavailable:
+- Installation of: MJPG-Streamer
+- All backup functions and the Log-Upload

 * The way how KIAUH interacts and writes to the users printer.cfg got changed. Usually KIAUH wrote everything directly into the printer.cfg. The way it will work from now on is, that a new file called `kiauh.cfg` will be created if there is something that needs to be written to the printer.cfg and everything gets written to `kiauh.cfg` instead. The only thing which then gets written to the users printer.cfg is `[include kiauh.cfg]`. This line will be located at the very top of the existing printer.cfg with a little comment as a note. The user can then decide to either keep the `kiauh.cfg` or take its content, places it into the printer.cfg directly and remove the `[include kiauh.cfg]`.

+# 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).
