 # Installation on existing client
 
-A straightforward way to test the lmn-client is to manually run the playbook on a freshly installed client.
-
-This can be done in the following ways:
-
-    On the client using ansible-pull
-    On the client by checking out the lmn-client repository and running the playbook locally
-    On a target device by checking out the lmn-client repository locally and executing the playbook against the target device
+An easy method to test the lmn-client is to run the playbook manual on a fresh installed client.

 ## Using codeberg repository and LinuxMuster.Net tftp
 
-### Requirements / firewall settings
-
-The computer on which the linuxclient is to be installed must have access to the Internet (add host to noproxy group)
-
-The following resources are downloaded from the internet:
-
-* The repository is provided by codeberg.org
-* the Linux kernel, the initial ramdisk and the installation files are loaded from debian.org.
-* mscorefonts from Microsoft

-## Using your own repository and LinuxMuster.Net tftp
-
-If you fork the lmn-client repository, you can customize the preseeding and inventory to your needs.
-Use the instructions in the previous section and customize the repository in `/srv/linbo/boot/grub/lmnclient.cfg`.
-
-It makes sense to encrypt your inventory via `ansible-vault`.
-When using encrypted inventories you have to provide the vault password by commenting in the two lines in the `/srv/linbo/boot/grub/lmnclient.cfg`.
-
-## Using your own repository and livebox tftp
-
-The next improvement will be to use your own livebox with following functionalities:
-
-* Providing linux kernel and initial ramdisk for installer
-* Can be used as cache for debian packages (aptcacher)
-* Can provide mscorefonts and libdvdcss (multimedia codecs)
-* Can be used to boot live systems (netboot) via pxe
-
-### Installing the livebox server
-
-* Install debian VM and configure network
-* Install additional packages: ansible  
-  `sudo apt install ansible`
-* Run livebox playbook  
-  `ansible-pull -i localhost, --url=https://salsa.debian.org/andi/debian-lan-ansible.git -C master livebox.yml`
-* Set DNS entry for your new livebox server
-
-### Modification LinuxMuster.Net server
-
