+  📄️ 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 (32bit)` 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)`:
+<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.

 This document covers possible important changes to KIAUH.
 
+### 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.

+### "plain text format" and "disable smart quotes" in "Textedit > Preferences"
+
+### Configure which camera to use
+#
+# Available options are:
+# - auto: tries first usb webcam, if that's not available tries raspi cam
+# - usb: only tries usb webcam
+# - raspi: only tries raspi cam
+#
+# Defaults to auto
+#
+#camera="auto"
+
+### Additional options to supply to MJPG Streamer for the USB camera
+#
+# See https://faq.octoprint.org/mjpg-streamer-config for available options
+#
+# Defaults to a resolution of 640x480 px and a framerate of 10 fps
+#
+#camera_usb_options="-r 640x480 -f 10"
+
+### Additional webcam devices known to cause problems with -f
+#
+# Apparently there a some devices out there that with the current 
+# mjpg_streamer release do not support the -f parameter (for specifying 
+# the capturing framerate) and will just refuse to output an image if it 
+# is supplied.
+#
+# The webcam daemon will detect those devices by their USB Vendor and Product
+# ID and remove the -f parameter from the options provided to mjpg_streamer.
+#
+# By default, this is done for the following devices:
+#   Logitech C170 (046d:082b)
+#   GEMBIRD (1908:2310)
+#   Genius F100 (0458:708c)
+#   Cubeternet GL-UPC822 UVC WebCam (1e4e:0102)
+#
+# Using the following option it is possible to add additional devices. If
+# your webcam happens to show above symptoms, try determining your cam's
+# vendor and product id via lsusb, activating the line below by removing # and 
+# adding it, e.g. for two broken cameras "aabb:ccdd" and "aabb:eeff"
+#
+#   additional_brokenfps_usb_devices=("aabb:ccdd" "aabb:eeff")
+#
+#
+#additional_brokenfps_usb_devices=()
+
+### Additional options to supply to MJPG Streamer for the RasPi Cam
+#
+# See https://faq.octoprint.org/mjpg-streamer-config for available options
+#
+# Defaults to 10fps
+#
+#camera_raspi_options="-fps 10"
+
+### Configuration of camera HTTP output
+#
+# Usually you should NOT need to change this at all! Only touch if you
+# know what you are doing and what the parameters mean.
+#
+# Below settings are used in the mjpg-streamer call like this:
+#
+#   -o "output_http.so -w $camera_http_webroot $camera_http_options"
+#
+# Current working directory is the mjpg-streamer base directory.
+#
+#camera_http_webroot="./www-mainsail"
+#camera_http_options="-n"
+
+### EXPERIMENTAL
+# Support for different streamer types.
+#
+# Available options:
+#   mjpeg [default] - stable MJPG-streamer
+#camera_streamer=mjpeg
