+*Deinonyxus* is a personal spin of the UBlue Bluefin DX image with the 🍦[Lix](https://lix.systems/) flavored Nix package manager baked in and a first-login bootstrap for simple declarative package management using [curator](https://codeberg.org/randogoth/curator).
 
 ## What’s inside
 - Base: `ghcr.io/ublue-os/bluefin-dx:latest` without Cockpit, Docker, Firefox, VS Code
+- Lix: multi-user install baked in with persistence at `/var/home/nix`; `nix-daemon.service` enabled.
+(D) - First-login bootstrap: installs Lix/nix packages `devbox`, `mc`, and `micro` via `curator`
 - System packages added: `syncthing`, `uv`, `vscodium`, `waydroid`;
-- System flatpaks added: Telegram Desktop, Waterfox browser
+- System flatpaks added: Telegram Desktop, Zen Browser
+
+## First login
+- Triggers for each non-root user on their first session.
+- Writes state to `~/.local/state/deinonyxus/curator-init.done`; delete it to rerun.
+- Bootstraps `~/.config/curator/inventory.toml` and runs `curator switch` with the packages set above.
 
 ## Just Recipes
 - `upgrade-nix`: upgrades to the latest version of Lix via the user profile. Replaces `nix upgrade-nix` which does not work with an immutable lowerdir `/nix/store` folder
