 `make env` creates `.env` and `docker-compose.override.yml` from their examples. `make recreate` starts the selected profiles, `make rebuild` builds the image first, `make logs`, `make restart` and `make down` do what they say.
 
+To deploy, `git pull && make deploy`. It runs `make pre-deploy`, which rebuilds the image only when something in the repository changed, then `docker compose up -d`. A deploy system with its own `up` step calls `make pre-deploy` before it and `make post-deploy` after. What was built is remembered as `refs/deploy/*` in the clone.
+
 `make dev` runs the Vite dev server on the host, `make fmt` formats, `make check` runs svelte-check and the linter.
