-## Provisioning
-> [nixos-anywhere](https://github.com/nix-community/nixos-anywhere) is the module used for provisioning
-
-Generate a new SSH host key in "$temp/etc/ssh" as per [this guide](https://nix-community.github.io/nixos-anywhere/howtos/secrets.html#example-decrypting-an-openssh-host-key-with-pass).
-
-Then run;
-```
-nix run github:nix-community/nixos-anywhere -- \
-  --disk-encryption-keys /tmp/secret.key /tmp/secret.key \
-  --extra-files "$temp" \
-  --flake .#<hostname> \
-  root@<ip>
-```
+## Quick start
+1. Copy SSH keypair and `known_hosts` to `~/.ssh`
+1. Import GPG keys and set ultimate trust with `echo "KEYID:6:" | gpg --import-ownertrust`
+1. `git clone git@git.vimium.com:jordan/nix-config.git projects/jordan/nix-config`
+1. `sudo nixos-rebuild switch --flake .#`
