+## stacks.sh
+
+`stacks.sh` is the primary management CLI. It wraps `docker compose` with glob-based multi-stack targeting, manages the update and backup systemd services, scaffolds new stacks, and generates shell completions.
+
+```bash
+./stacks.sh help
+```
+
+**Stack commands** — all accept one or more stack names or glob patterns (omit for all stacks):
+
+```bash
+./stacks.sh ls                        # list all stacks with live container status
+./stacks.sh ps gitea                  # container status table
+./stacks.sh up                        # start all stacks
+./stacks.sh up gitea traefik          # start specific stacks
+./stacks.sh down 'g*'                 # stop stacks matching glob
+./stacks.sh restart 'g*,traefik'      # glob + exact name, comma-separated
+./stacks.sh pull --parallel           # pull all images in parallel
+./stacks.sh logs -f gitea             # follow logs
+./stacks.sh logs -n 100 gitea n8n    # tail multiple stacks
+./stacks.sh exec gitea gitea gitea admin user list  # exec in container
+./stacks.sh run passbolt passbolt bin/cake passbolt healthcheck
+```
+
+**Service management:**
+
+```bash
+./stacks.sh update install     # link & enable systemd update timer
+./stacks.sh update run         # run update now
+./stacks.sh update status      # show timer/service status
+./stacks.sh update logs        # show journal logs
+
+./stacks.sh backup install     # link & enable systemd backup timer
+./stacks.sh backup run         # run backup now
+./stacks.sh backup snapshots   # list restic snapshots
+```
+
+**Scaffold a new stack:**
+
+```bash
+./stacks.sh new myapp                      # basic stack with Traefik labels
+./stacks.sh new myapp --db postgres        # with Postgres service
+./stacks.sh new myapp --db postgres --redis  # with Postgres + Redis
+./stacks.sh new myapp --no-traefik         # expose port instead of Traefik
+```
+
+Generates `compose.yml` (with healthchecks, `../.data/` volumes, Traefik labels) and `.env.example`.
+
+**Shell completion:**
+
+```bash
+# Dynamic — discovers stacks at tab-complete time (default)
+./stacks.sh completion zsh --install
+
+# Static — bakes current stack list in; useful on the VPS
+./stacks.sh completion zsh --static --install
+```
+
+**Global flags:** `--dry-run`, `--parallel`, `--verbose`, `--quiet`
