+Manual
+======
+
+Each script `${FULL_SCRIPTNAME}.sh` has it's corresponding manual here:
+ - `manuals/${FULL_SCRIPTNAME}.sh.md`
+
+According to the rule above, this directory `manuals/core/*`  
+has the same structure as `../core/*` and contains all manuals explaining the core functionality.
+
+And this directory `manuals/script/*`  
+has the same structure as `../script/*` and contains all manuals explaining the purpose of each script.
+
+
+
+Core functionality
+------------------
+
+This set of scripts is the absolute minimum to provide the core functionality:
+ - `setupCoreOntoThisHost.sh` bootstraps an empty new host, after the scripts repository was cloned  
+   [Read this for further details](./setupCoreOntoThisHost.sh.md)
+ - `setupCoreOntoThisHost.sh` needs [`../core/addAndCheckGitRepository.sh`](./core/addAndCheckGitRepository.sh.md)
+ - `setupCoreOntoThisHost.sh` needs [`../core/addNormalUser.sh`](./core/addNormalUser.sh.md)
+ - `setupCoreOntoThisHost.sh` needs [`../core/addToCrontabEveryHour.sh`](./core/addToCrontabEveryHour.sh.md)

-Monitoring - How it works
+How to setup a monitoring dashboard
-=========================
+===================================
 
-Basics
+Inspired by: https://pimylifeup.com/ubuntu-chromium-kiosk/
-------
 
-You have to set up the monitoring host first. That host will monitor your other machines.
+Steps
-Execute `/cis/script/monitor/setupMonitoringHost.sh` to start the process.
+-----
 
-As usual you can configure this feature via definitions.
+
-```
+
-# Path of this feature's scripts       : '/cis/script                 /monitor'
+### 1.) Install Ubuntu Server (no desktop) on your computer than set hostname and timezone.
-# Path of the corresponding definitions: '/cis/definitions/YOUR.DOMAIN/monitor'
+
-ls -lha '/cis/script/monitor'
+```sh
-ls -lha '/cis/definitions/YOUR.DOMAIN/monitor'
+hostnamectl set-hostname check.local
+timedatectl set-timezone Europe/Berlin
 ```
 
-You can modify the appearance and place your own `check.css` or `logo.png` into the definitions folder:
 
- - /cis/definitions/YOUR.DOMAIN/monitor/check.css
- - /cis/definitions/YOUR.DOMAIN/monitor/logo.png
 
-After the change, you have to call `/cis/script/monitor/setupMonitoringHost.sh` again,  
+### 2.) Install minimal GUI and Tools.
-because it creates links in '/var/www/html/' and gives the definitions priority over the script.  
+
-Additional you need to configure a webserver to publish the site. 
+```sh
+apt install ubuntu-desktop-minimal
+apt install language-pack-gnome-de
+apt install xdotool
+apt install dbus-x11
+```
 
 
 
-Dashboard
+### 3.) Create a kiosk user with home-directory.
----------
 
-You can set up an dashboard following this manual [SETUP_DASHBOARD.md](SETUP_DASHBOARD.md)
+```sh
+useradd -m kiosk
+```
+
+and disable Welocme-Screen
+```sh
+echo "yes" > /home/kiosk/.config/gnome-initial-setup-done
+```
+
+
+
+### 4.) Edit following file `nano /etc/gdm3/custom.conf` to turn of wayland and turn on autologin for user 'kiosk'.
+
+```
+[daemon]
+# Uncomment the line below to force the login screen to use Xorg
+#WaylandEnable=false
+
+WaylandEnable=false
+
+# Enabling automatic login
+#  AutomaticLoginEnable = true
+#  AutomaticLogin = user1
+
+AutomaticLoginEnable = true
+AutomaticLogin = kiosk
+```
+
+
+
+### 5.) Configure GUI of user kiosk to prevent monitor from sleeping
+
+```sh
+#gsettings list-recursively
+
+# Does not work
+#sudo -u kiosk gsettings set org.gnome.desktop.session idle-delay 0
+
+# Set idle-delay from "uint32 300" to "uint32 0", needs 'apt install dbus-x11'
+# You can check the value in "GUI-Session of kiosk -> Settings -> Power"
+sudo -u kiosk dbus-launch dconf write /org/gnome/desktop/session/idle-delay "uint32 0"
+```
+
+
+
+### 6.) Create custom service to start firefox loading the page.
+
+Therefore create a file `/etc/systemd/system/kiosk.service` with this content:
+
+```
+[Unit]
+Description=Firefox Kiosk
+Wants=graphical.target
+After=graphical.target
+
+[Service]
+Environment=DISPLAY=:0
+# Set firefox language, needs 'apt install language-pack-gnome-de' 
+Environment=LANG=de_DE.UTF-8
+Type=simple
+# Always a fresh firefox ('-' allow error if common does not exist)
+ExecStartPre=-/usr/bin/rm -r /home/kiosk/snap/firefox/common
+# Move Mouse (should also work on small screens), needs 'apt install dbus-x11'
+ExecStartPre=/usr/bin/xdotool mousemove 4096 2160
+# See: https://wiki.mozilla.org/Firefox/CommandLineOptions (just -kiosk URL => Start-Assistant, so use -url too)
+ExecStart=/usr/bin/firefox -fullscreen -kiosk -url http://monitor.example.net/check.html
+Restart=always
+RestartSec=30
+User=kiosk
+Group=kiosk
+
+[Install]
+WantedBy=graphical.target
+```
+
+
+
+### 7.) Enable the service and reboot
+
+```sh
+systemctl enable kiosk
+reboot
+```
+
+
+
+Troubleshouting
+---------------
+
+```
+systemctl disable pd-mapper.service
+apt purge cloud-init -y && apt autoremove --purge -y
+```

-### 3.) Create a kiosk user with home-directory.
-
-```sh
-useradd -m kiosk
-```
-
-and disable Welocme-Screen
-```sh
-echo "yes" > /home/kiosk/.config/gnome-initial-setup-done
-```
-
-
-
-### 4.) Edit following file `nano /etc/gdm3/custom.conf` to turn of wayland and turn on autologin for user 'kiosk'.
-
-```
-[daemon]
-# Uncomment the line below to force the login screen to use Xorg
-#WaylandEnable=false
-
-WaylandEnable=false
-
-# Enabling automatic login
-#  AutomaticLoginEnable = true
-#  AutomaticLogin = user1
-
-AutomaticLoginEnable = true
-AutomaticLogin = kiosk
-```
-
-
-
-### 5.) Configure GUI of user kiosk to prevent monitor from sleeping
-
-```sh
-#gsettings list-recursively
-
-# Does not work
-#sudo -u kiosk gsettings set org.gnome.desktop.session idle-delay 0
-
-# Set idle-delay from "uint32 300" to "uint32 0", needs 'apt install dbus-x11'
-# You can check the value in "GUI-Session of kiosk -> Settings -> Power"
-sudo -u kiosk dbus-launch dconf write /org/gnome/desktop/session/idle-delay "uint32 0"
-```
-
-
-
-### 6.) Create custom service to start firefox loading the page.
-
-Therefore create a file `/etc/systemd/system/kiosk.service` with this content:
-
-```
-[Unit]
-Description=Firefox Kiosk
-Wants=graphical.target
-After=graphical.target
-
-[Service]

-# Always a fresh firefox ('-' allow error if common does not exist)
-ExecStartPre=-/usr/bin/rm -r /home/kiosk/snap/firefox/common
-# Move Mouse (should also work on small screens), needs 'apt install dbus-x11'
-ExecStartPre=/usr/bin/xdotool mousemove 4096 2160
-# See: https://wiki.mozilla.org/Firefox/CommandLineOptions (just -kiosk URL => Start-Assistant, so use -url too)
-ExecStart=/usr/bin/firefox -fullscreen -kiosk -url http://monitor.example.net/check.html
-Restart=always
-RestartSec=30
-User=kiosk
-Group=kiosk
-
-[Install]
-WantedBy=graphical.target
-```
-
-
-
-### 7.) Enable the service and reboot
-
-```sh
-systemctl enable kiosk
-reboot
-```
-
-
-
-Troubleshouting

-Issuing SSL certificates
-========================
-There are two modes you can use the script `renewCerts.sh`.
-
-1. dns
-2. http
-
-
-
-Dns mode
---------
-This mode is meant to use inside a docker container defined by the `Dockerfile`.
-To configure, build and run the Container there is a file `docker-compose.yml.template`.
-You can copy this file to `docker-compose.yml` and set the needed environment variables there.
-
-- __AUTOACME_CONTAINER_HOSTNAME__  
-  is used to enable the use of the host name within the container.
-  For example, for meaningful commit messages.
-- __AUTOACME_GIT_REPOSITORY_VIA_SSH__ (optional)  
-  is used to specify a Git repository to which the keys and certificates are transferred.
-  Therefore, SSH keys are generated on first launch (`docker compose up -d`) and the repository is cloned to `~/acmeResults/`.
-  The public key must be granted __write access__ to the repository  
-  (e.g. as repository's deploy key).
-  The key can be viewed via `docker compose logs`.
-- __AUTOACME_PATH_IN_GIT_REPOSITORY__  (optional)  
-  specifies a path inside the repository were the certiticates are saved.  
-  (e.g. AUTOACME_PATH_IN_GIT_REPOSITORY="/foo/bar/" => /root/autoACME/foo/bar/your-domain.net/fullchain.crt)
-- __AUTOACME_DNS_PROVIDER__  
-  sets the provider modul of acme.sh used to communicate with your domain provider.  
-  (For further information see: https://github.com/acmesh-official/acme.sh/wiki/dnsapi)
-
-You may have to set additional environment variables depending on your provider...
-
-
-
-### Manual docker commands
-Instead of using `docker compose` you can build and run the container manually:
-```
-docker build -t cis/autoacme .
-docker run --name autoacme -d cis/autoacme
-```
-This may be useful for investiagtion...
-
-
-Http mode
----------
-If you plan to use `renewCerts.sh` directly on your host computer this mode may fit your needs.
-Here you need a `nginx` webserver. The domain have to point to it and following configuration is needed:
-
-1. The content of folder `/var/www/letsencrypt/.well-known/acme-challenge/` has to be accessable via `http://your-domain.net/.well-known/acme-challenge/`
-2. The certificates are stored to `/etc/nginx/ssl`. If this folder is a git repository then changes will be commited and pushed.
-3. An entry into the crontab is needed to do automatic updates.
