+# titanium
+
+This is my primary workstation / gaming pc.
+It will generally be the most out of sync with the repo, as there will be a lot
+of software I experiment with, which I simply forget to commit here. Everything
+of importance will find it's way to this repo.
+
+## Non-Deterministic Post-Install Steps
+
+Rearrange Monitors in Gnome Display Settings
+
+Use a fido2 key (YubiKey) to decrypt luks
+```bash
+sudo -E -s systemd-cryptenroll --fido2-device=auto /dev/disk/by-partlabel/disk-main-luks
+```
+
+## Installing Remotely
+```bash
+nix run github:nix-community/nixos-anywhere -- --flake .#titanium <ssh-addr>
+```
