 ## Installation
 
-For disk configuration we use disko, this means that installing the system from the configuration is just a single command:
+For disk configuration we use disko, but for secrets management we use sops-nix and the particular setup makes the installation process a bit more involved. It is required that the computer from which the installation is being run has access to the `nixos-secrets` repository, otherwise you will need to manually add the required ssh keys to the installation image. 
+```bash
+# Load into the installer
+sudo passwd # Set a root password
 
+# From a machine with network access to the installer
+# and access to the nixos-secrets repo
+ssh -A root@(installer-ip)
+
+# Set up disks
+nix-shell -p disko
+disko --mode disko --flake git+https://git.bulthuis.dev/Jan/nixos-config#(system)
+exit
+
+# Install NixOS
+nixos-install --no-channel-copy --no-root-password --flake git+https://git.bulthuis.dev/Jan/nixos-config#(system)
+
+# Set up host credentials for access to the secrets
+cd /mnt/persist/system/etc/sops
+touch sops_ed25519_key 
+chmod 600 sops_ed25519_key
+nano sops_ed25519_key
 ```
-sudo nix --experimental-features "nix-command flakes" run "github:nix-community/disko/latest#disko-install" -- --flake git+https://git.bulthuis.dev/Jan/dotfiles#<hostname> --disk main /dev/sda
+If `nixos-install` is being stopped by the OOM-killer, you can try adding `-j 1` to limit the amount of jobs that will be executed at the same time to 1. It might require running nixos-install multiple times untill it has managed to download all requirements and slowly start building the rest of the system.
+
+## Updating
+
+To update the system configuration, it is a single command:
+```bash
+sudo system-update
 ```
+Or if this shell script has not been installed for some reason:
+```bash
+sudo nixos-rebuild switch --flake git+https://git.bulthuis.dev/Jan/nixos-config
+```
+Sometimes it may be necessary to reboot of course.
