+## Functions and Features:
+
+### Core Functions:
+
+- **Installing** of the Klipper Firmware to your Raspberry Pi or other Linux Distribution which makes use of init.d.
+- **Installing** of several different web interfaces such as Duet Web Control, Mainsail or OctoPrint including their dependencies.
+- **Installing** of the Moonraker API 
+- **Updating** of all the listed installations above excluding OctoPrint. For updating OctoPrint, please use the OctoPrint interface!
+- **Removing** of all the listed installations above.
+- **Backup** of all the listed installations above.
+
+What also is possible:
+- Build the Klipper Firmware
+- Flash the MCU 
+- Read ID of the currently connected printer (only one at the time)
+- Write necessary entries to your printer.cfg, some of them customizable right in the CLI.
+
+For a list of additional features and their descriptions please see:

-## Functions and Features:
-
-### Core Functions:
-
-- **Install:** Klipper Firmware, dwc2-for-klipper-socket + Duet Web Control, Moonraker + Mainsail, OctoPrint
-- **Update:** Klipper Firmware, dwc2-for-klipper-socket + Duet Web Control, Moonraker + Mainsail
-- **Backup:** Klipper Firmware, dwc2-for-klipper-socket + Duet Web Control, Moonraker + Mainsail, OctoPrint
-- **Remove:** Klipper Firmware, dwc2-for-klipper-socket + Duet Web Control, Moonraker + Mainsail, OctoPrint
-- Build Klipper Firmware
-- Flash MCU
-- Read ID of the currently connected printer (only one at the time)
-- Write several entries to your printer.cfg, some of them customizable right in the console
-  - Before writing to an existing printer.cfg the script will create a backup! (better safe than sorry!)
-
-### Features:
-
-- Automatic dependency check:
-  - If packages are missing on your machine but needed for the asked task, the script will automatically install them
-- Switch between Klipper Forks:
-  - [origin/master](https://github.com/KevinOConnor/klipper/tree/master), [scurve-shaping](https://github.com/dmbutyugin/klipper/tree/scurve-shaping), [scurve-smoothing](https://github.com/dmbutyugin/klipper/tree/scurve-smoothing), [moonraker](https://github.com/Arksine/klipper/tree/dev-moonraker-testing)
-  - 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
-- Preconfigure OctoPrint:
-  - When installing OctoPrint, a config is created which preconfigures your installation to be used with Klipper
-    - 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 and OctoPrint at the same time to prevent them interfering with each other
-- Set up reverse proxy for DWC2, Mainsail and OctoPrint and changing the hostname:
-
-  - The script can install and configure Nginx for the selected webinterface. This will allow you to make your webinterface reachable over an URL like `<hostname>.local`
-  - Example: If you name the host "mainsail" and set up a reverse proxy, type `mainsail.local` in your webbrowser to open the Mainsail webinterface
-
-  to be continued...
-
-## What this script can't do:
-
-- Updating OctoPrint -> Use OctoPrint for updating!
-- Setting up webcam related stuff:
-
-  - If you want to use a webcam you have to install the dependencies and configurations yourself. I can't test this stuff sufficient enough due to me not having/using a webcam and therefore it's just too much work for me to set up an installation script which works, at best, with the first try.
-
-    There are install instructions (at least in case of OctoPrint) available:
-    [Setting up OctoPrint on a Raspberry Pi running Raspbian](https://community.octoprint.org/t/setting-up-octoprint-on-a-raspberry-pi-running-raspbian/2337)
-    (look for "Optional: Webcam")
-
 ## Q&A
 
-**_Q: Can i install octoprint with this script?_**
-
-**A:** ~~Soon™~~ Yes :)
-
 **_Q: Can i use this script to install multiple instancec of Klipper on the same Pi? (Multisession?)_**
 
 **A:** No, and at the moment i don't plan to implement this function. For multisession installations take a look at this script manu7irl created: https://github.com/manu7irl/klipper-DWC2-installer . Keep in mind that klipper-DWC2-installer and KIAUH are **NOT** compatible with each other.
