-Runs in Docker, locally the same way as in production. Each part in `{{ parts | join('/`, `') }}/` brings its own `docker-compose.yml`, included from the root one. `COMPOSE_PROFILES` in `.env` selects the services that run on this machine. `docker-compose.override.yml` in each part holds what differs between machines: published ports and the aliases on the external `caddy` network.
-
 ```sh
-make env
-make recreate
+make env       # .env and docker-compose.override.yml from the examples
+make recreate  # the services in COMPOSE_PROFILES
+make check
 ```
 
-`make env` creates `.env` from the examples of every part and copies each `docker-compose.override.yml.example`. `make recreate` starts the selected profiles, `make rebuild` builds the images first, `make logs`, `make restart` and `make down` do what they say.
-
-To deploy, `git pull && make deploy`. It runs `make pre-deploy` in every part, which builds images only when their inputs changed and applies migrations, then `docker compose up -d`, then `make post-deploy`, which restarts the services whose mounted code changed. A deploy system with its own `up` step calls the two hooks around it. What was built and started is remembered as `refs/deploy/*` in the clone.
-
-In the fleet, production is deployed from `infra/komodo` instead (git mode of Komodo, see `docs/architecture.md` there): Komodo clones this repo, and a layer plus `deploy.sh` in the stack's directory tag images by the hash of what they bake in, write `.env` from sops and run migrations before the code. The repo only has to stay a plain recipe: images built from `build:` in compose, migrations as the `migrator` service when there is a database, `caddy/site.caddy`. `make deploy` and `refs/deploy/*` are for a checkout deployed by hand.
-
-`make fmt`, `make check` and `make build` run in every part. Part-specific targets live in the part's own Makefile: `make -C {{ parts[0] }} ...`.
+Parts: `{{ parts | join('/`, `') }}/`, each with its own Makefile.
