+## ./home
+- [home-manager](https://github.com/nix-community/home-manager) configuration files
+- foot, tmux, and zsh are configured in Nix
+- nvim, rofi, sway, waybar are configured in their own literature and symlinked to $XDG_CONFIG_HOME with home-manager
+
+## ./hosts
+- [`hosts/common.nix`](hosts/common.nix): configuration that makes sense on all computers
+- [`hosts/zsh.nix`](hosts/zsh.nix): for computers that have the power to run zsh
+### ./hosts/ytnix
+- personal laptop
+- a single [`default.nix`](hosts/ytnix/default.nix) that could be modularized but works for now
+
+### ./hosts/chunk
+- the overworked server with 5% SLA
+- very short and concise [`default.nix`](hosts/chunk/default.nix)
+- services organized in their modules
+- some services run through `virtualisation.oci-containers`:
+    - [immich](hosts/chunk/immich.nix)
+    - [conduwuit](hosts/chunk/conduwuit.nix)
+
+### ./hosts/titan
+- got this cause chunk would go down way too often :(
+- hosted on azure for "reliability"
+- runs:
+    - [ghost](hosts/titan/ghost.nix) (through `virtualisation.oci-containers`)
+    - [uptime-kuma](hosts/titan/uptime-kuma.nix)
+    - [ntfy-sh](hosts/titan/ntfy.nix)
+
+## ./secrets
+- secrets
+- see [`.sops.yaml`](.sops.yaml) for who privy to what
+
+## backups
+- hourly borgbackup to [rsync.net](https://rsync.net)
+- see [modules/backup](modules/backup.nix)
+
+## monitoring
+- [status.cything.io](https://status.cything.io/): uptime kuma (reliable)
+- [grafana.cything.io](https://grafana.cything.io/): some real-time metrics here; unlike the status page this will go kaput often
