-# Create host with disko-install
-How to use disko-install is described here: https://github.com/nix-community/disko/blob/master/docs/disko-install.md
----
-Here are the exact steps to get bakunin running:  
-First create machines/hostname/configuration.nix  
-Add hosts nixosConfiguration in machines/configurations.nix  
-Boot nixos installer on the Machine.  
+# Create host with nixos-anywhere
+We use a nixos-anywhere wrapper script to deploy new hosts.
+The wrapper script takes care of copying persistent host keys before calling nixos-anywhere.
+
+To accomplish that boot the host from a nixos image and setup a root password.
 ``` bash
-# establish network connection
-wpa_passphrase "network" "password" > wpa.conf
-wpa_supplicant -B -i wlp3s0 -c wpa.conf
-ping 8.8.8.8
-# if that works continue
+sudo su
+passwd
+```
 
-# generate a base hardware config
-nixos-generate-config --root /tmp/config --no-filesystems
+After that get the hosts ip using `ip a` and start deployment from your own machine:
 
-# get the infra repo
-nix-shell -p git
-git clone https://git.dynamicdiscord.de/kalipso/infrastructure
-cd infrastructure
-
-# add the new generated hardware config (and import in hosts configuration.nix)
-cp /tmp/config/etc/nixos/hardware-configuration.nix machines/bakunin/
-
-# check which harddrive we want to install the system on
-lsblk #choose harddrive, in this case /dev/sda
-
-# run nixos-install on that harddrive
-sudo nix --extra-experimental-features flakes --extra-experimental-features nix-command run 'github:nix-community/disko/latest#disko-install' -- --flake .#bakunin --disk main /dev/sda
-
-# this failed with out of memory
-# running again showed: no disk left on device
-# it seems the usb stick i used for flashing is way to small
-# it is only 
-# with a bigger one (more than 8 gig i guess) it should work
-# instead the disko-install tool i try the old method - first partitioning using disko and then installing the system
-# for that i needed to adjust ./machines/modules/disko/btrfs-laptop.nix and set the disk to "/dev/sda"
-
-sudo nix --extra-experimental-features "flakes nix-command" run 'github:nix-community/disko/latest' -- --mode format --flake .#bakunin
-
-# failed with no space left on device.
-# problem is lots of data is written to the local /nix/store which is mounted on tmpfs in ram
-# it seems that a workaround could be modifying the bootable stick to contain a swap partition to extend tmpfs storage
+``` bash
+# from infrastrucutre repository root dir:
+nix develop .#
+remote-install hostname 10.0.42.23
 ```
