-## Kickstart installation
-
-[Kickstart](https://docs.fedoraproject.org/en-US/fedora/f35/install-guide/advanced/Kickstart_Installations/) is a method for automating the installation of Fedora/Redhat based Linux distributions.
-It works by using a Kickstart (`.ks`) file which contains a configuration of all the installation options which the user would usually manually enter using the installation wizard.
-
-We have prepared such a Kickstart file which installs Fedora with our recommended configuration as well as [installs VILLASnode from source](#source) as described above.
-
-To use it, you will need to download a [Netinstall image of Fedora Server](https://getfedora.org/de/server/download/) and copy it to a USB stick or opticial disk.
-You also need to interrupt the initial boot of the Fedora installer, in the boot manager and append the following Kernel command line:
-
-```text
-inst.ks=https://raw.githubusercontent.com/VILLASframework/node/master/packaging/live-iso/villas.ks
-```
-
-Further details on how to start the Kickstart installation can be found [in the official Fedora documentation](https://docs.fedoraproject.org/en-US/fedora/f35/install-guide/advanced/Kickstart_Installations/#sect-kickstart-installation-starting).
