+  📄️ Instructions 📄
+</h2>
+
+### 📋 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.
+
+* 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>
+
+* 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.
+

+
+## 📄 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)。
+
+这些步骤**仅适用于**您实际使用树莓派的情况。如果您想使用其他单板计算机（如香橙派或其他 Pi 衍生产品），
+请查找如何将合适的 Linux 镜像写入 SD 卡（通常使用 Balena Etcher）。
+同时确保 KIAUH 能够在您要安装的 Linux 发行版上运行。
+您在使用基于 Debian 11 Bullseye 的系统时可能会获得最佳体验。
+请阅读本文档下方的注意事项。
+
+### 💾 下载并使用 KIAUH
+
+**📢 免责声明：使用此脚本的风险由您自行承担！**
+
+* **第一步：**
+要下载此脚本，需要先安装 git。
+如果您不确定是否已安装 git，请运行以下命令：
+```shell
+sudo apt-get update && sudo apt-get install git -y
+```
+
+* **第二步：**
+安装完 git 后，
+使用以下命令将 KIAUH 下载到您的主目录：
+
+```shell
+cd ~ && git clone https://github.com/dw-0/kiauh.git
+```
+
+* **第三步：**
+最后，通过运行以下命令启动 KIAUH：
+
+```shell
+./kiauh/kiauh.sh
+```
+
+* **第四步：**
+您现在应该会看到 KIAUH 的主菜单。
+根据您的选择，
+您会看到几个可选操作。
+要选择某个操作，只需在 "Perform action" 提示后输入对应的数字并按回车键确认。
+
+## ❗ 注意事项
+
+### **📋 请查看 [更新日志](docs/changelog.md) 以了解可能的重要更新！**
+
+- 主要在 Raspberry Pi OS Lite (Debian 10 Buster / Debian 11 Bullseye) 上测试
+    - 其他基于 Debian 的发行版（如 Ubuntu 20 到 22）也可能正常工作
+    - 据报告在 Armbian 上也可用，但未进行详细测试
+- 在使用此脚本的过程中，
+您会被要求输入 sudo 密码。
+因为有几个功能需要 sudo 权限。

 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
+
+### 2022-10-20
+KIAUH has now reached major version 5 !
+
+Recently Moonraker introduced some changes which makes it necessary to change the folder structure of printer setups.
+If you are interested in the details, check out this PR: https://github.com/Arksine/moonraker/pull/491 \
+Although Moonraker has some mechanics available to migrate existing setups to the new file structure with the use of symlinks, fresh and clean installs
+should be considered.
+
+The version jump of KIAUH to v5 is a breaking change due to those major changes! That means v4 and v5 are not compatible with each other!
+This is also the reason why you will currently be greeted by a yellow notification in the main menu of KIAUH leading to this changelog.
+I decided to disable a few functions of the script and focus on releasing the required changes to the core components of this script.
+I will work on updating the other parts of the script piece by piece during the next days/weeks.
+So I am already sorry in advance if one of your desired components you wanted to install or use temporarily cannot be installed or used right now.
+
+The following functions are currently unavailable:
+- Installation of: KlipperScreen, Obico, Octoprint, MJPG-Streamer, Telegram Bot and PrettyGCode
+- All backup functions and the Log-Upload
+
+**So what is working?**\
+Installation of Klipper, Moonraker, Mainsail and Fluidd. Both, single and multi-instance setups work!\
+As already said, the rest will follow in the near future. Updating and removal of already installed components should continue to work.
+
+**What was removed?**\
+The option to change Klippers configuration directory got removed. From now on it will not be possible anymore to change
+the configuration directory from within KIAUH and the new filestructure is enforced.
+
+**What if I don't have an existing Klipper/Moonraker install right now?**\
+Nothing important to think about, install Klipper and Moonraker. KIAUH will install both of them with the new filestructure.
+
+**What if I have an existing Klipper/Moonraker install?**\
+First of all: Backups! Please copy all of your config files and the Moonraker database (it is a hidden folder, usually `~/.moonraker_database`) to a safe location.
+After that, uninstall Klipper and Moonraker with KIAUH. You can then proceed and re-install both of them with KIAUH again. It is important that you are on KIAUH v5 for that!
+Once everything is installed again, you need to manually copy your configuration files from the old `~/klipper_config` folder to the new `~/printer_data/config` folder.
+Previous, by Moonraker created symlinks to folder of the old filestructure will not work anymore, you need to move the files to their new location now!
+Do the same with the two files inside of `~/.moonraker_database`. Move/copy them into `~/printer_data/database`. If `~/printer_data/database` is already populated with a `data.mdb` and `lock.mdb`
+delete them or simply overwrite them. Nothing should be lost as those should be empty database files. Anyway, you made backups, right?
+You can now proceed and restart Moonraker. Either from within Mainsail or Fluidd, or use SSH and execute `sudo systemctl restart moonraker`.
+If everything went smooth, you should be good to go again. If you see some Moonraker warnings about deprecated options in the `moonraker.conf`, go ahead and resolve them.
+I will not cover them in detail here. A good source is the Moonraker documentation: https://moonraker.readthedocs.io/en/latest/configuration/
+
+**What if I have an existing Klipper/Moonraker multi-instance install?**\
+Pretty much the same steps that are required for single instance installs apply to multi-instance setups. So please go ahead and read the previous paragraph if you didn't already.
+Make backups of everything first. Then remove and install the desired amount of Klipper and Moonraker instances again.
+Now you need to move all config and database files to their new locations.\
+Example with an instance called `printer_1`:\
+The config files go from `~/klipper_config/printer_1` to `~/printer_1_data/config`.
+The database files go from `~/.moonraker_database_1` to `~/printer_1_data/database`.
+Now restart all Moonraker services. You can restart all of them at once if you launch KIAUH, and in the main menu type `restart moonraker` and hit Enter.
+
+I hope I have covered the most important things. In case you need further support, the official Klipper Discord is a good place to ask for help.
+
+### 2022-08-15
+Support for "Obico for Klipper" was added! Huge thanks to [kennethjiang](https://github.com/kennethjiang) for helping me with the implementation!
+
+### 2022-05-29
+KIAUH has now reached major version 4 !
+* feat: Klipper can be installed under Python3 (still considered as experimental)
+* feat: Klipper can be installed from custom repositories / inofficial forks
+* feat: Custom instance name for multi instance installations of Klipper
+  * Any other multi instance will share the same name given to the corresponding Klipper instance
+  * E.g. klipper-voron2 -> moonraker-voron2 -> moonraker-telegram-bot-voron2
+* feat: Option to allow installation of / updating to unstable Mainsail and Fluidd versions
+  * by default only stable versions get installed/updated
+* feat: Multi-Instance OctoPrint installations now each have their own virtual python environment
+  * allows independent installation of plugins for each instance
+* feat: Implementing the use of shellcheck during development
+* feat: Implementing a simple logging mechanic
+* feat: Log-upload function now also allows uploading other logfiles (kiauh.log, webcamd.log etc.)
+* feat: added several new help dialogs which try to explain various functions
+* fix: During Klipper installation, checks for group membership of `tty` and `dialout` are made
+* refactor: rework of the settings menu for better control the new KIAUH features
+* refactor: Support for DWC and DWC-for-Klipper has been removed
+* refactor: The backup before update settings were moved to the KIAUH settings menu
+* refactor: Switch branch function has been removed (was replaced by the custom Klipper repo feature)
+* refactor: The update manager sections for Mainsail, Fluidd and KlipperScreen were removed from the moonraker.conf template
+  * They will now be individually added during installation of the corresponding interface
+* refactor: The rollback function was reworked and now also allows rollbacks of Moonraker
+  * It now takes numerical inputs and reverts the corresponding repository by the given amount instead
+  * KIAUH does not save previous states to its config anymore like it did with the previous approach
+
+
 ### 2022-01-29
 * Starting from the 28th of January, Moonraker can make use of PackageKit and PolicyKit.\

-# Feature List:
-
-- **Automatic dependency check:**\
-If packages are missing but needed for the asked task, the script will automatically install them
-- **Switch between different Klipper Forks:**\
-[origin/master](https://github.com/KevinOConnor/klipper/tree/master) or [scurve-shaping](https://github.com/dmbutyugin/klipper/tree/scurve-shaping) or [scurve-smoothing](https://github.com/dmbutyugin/klipper/tree/scurve-smoothing)\
-The update function of the script will always update the currently selected/active fork!
-- **Toggle auto-create backups before updating:**\
-When enabled, a backup of the installation you want to update is made prior updating
-- **Rollback:**\
-When updating Klipper, KIAUH saves the current commit hash to a local ini-file. In case of an unsuccesfull update you can use this function to quickly revert back to the commit with the hash you updated from.
-- **Preconfigure OctoPrint:**\
-When installing OctoPrint, a config is created which preconfigures your installation to be used with Klipper.\
-That means:
-  - adding the restart/shutdown commands for OctoPrint
-  - adding the serial port `/tmp/printer`
-  - set the behavior to "Cancel any ongoing prints but stay connected to the printer"
-- **Enable/Disable OctoPrint Service:**\
-Usefull when using DWC2/Mainsail/Fluidd and OctoPrint at the same time to prevent them interfering with each other
-
-- **Installing a G-Code Shell Command extension:**\
-For further information about that extension please see the  [G-Code Shell Command Extension Doc](gcode_shell_command.md)
-
-- **Uploading logfiles:**\
-You can directly upload logfiles like klippy.log, moonraker.log and dwc2.log from the KIAUH main menu for providing them for troubleshooting purposes.

 The following short example shows storing the extruder temperature into a variable, passing that value with a parameter to a `gcode_shell_command`, which then, 
 once the gcode_macro runs and the gcode_shell_command gets called, executes the `script.sh`. The script then echoes a message to the console (if `verbose: True`) 
 and writes the value of the parameter into a textfile called `test.txt` located in the home directory.

+### Additional webcam devices known to cause problems with -f

+# Apparently there a some devices out there that with the current

+# The webcam daemon will detect those devices by their USB Vendor and Product

+#
+# Using the following option it is possible to add additional devices. If
+# your webcam happens to show above symptoms, try determining your cam's
