-This is my NixOS flake, including all my system dotfiles and settings.
+# Snowflake
 
-It contains configurations for multiple host systems, and is
-split into nixos modules and home-manager modules,
-which are then imported from each host according to it's needs.
+My personal NixOS flake, building dotfiles for all of my systems and servers.
 
-Shell scripts built from the flake at <https://github.com/joinemm/bin>
+The configuration is modular, with modules imported to each host as needed.

+## Installing to remote servers

+The included script will install the system, and add `ssh_host_ed25519_key` specified in `secrets.yaml`
+
+```
+./scripts/install .#$HOST $REMOTE_IP --secrets hosts/$HOST/secrets.yaml

+
+## SD card images
 
-This goes for cloud hosts like hetzner. The target server needs to have passwordless sudo for the user you log in as.
+The raspberry pi config can be built as flashable sd card image for initial installation:
 
 ```
-nixos-rebuild switch --flake .#$HOST --use-remote-sudo --target-host $IP
+nix build .#nixosConfigurations.archimedes.config.system.build.sdImage
+
+# flash to sd card
+lsblk # check sd card device
+sudo dd if=result/nixos-sd-image-xxx-aarch64-linux.img of=/dev/sda bs=4M conv=fsync status=progress
 ```
+
+This sd card can now be inserted into a raspberry pi and it will boot the configuration.
