 # frontend-svelte
 
-Copier template for a SvelteKit frontend, either as a `frontend/` part next to other parts or alone at the root of the project (`layout`): SvelteKit on Bun with Tailwind v4, ultracite (biome) and optional shadcn-svelte, served by a Bun server with SSR, as a static SPA behind `serve.ts`, or as a static SPA that the backend api serves from `frontend/build`.
-
-Ships `frontend/docker-compose.yml` with root-relative paths and profiles per service, `docker-compose.override.yml.example` (the `caddy` network aliases, copied by `make env`), a `Makefile` with `fmt`, `check`, `build` and `dev`, `.env.example`, `CLAUDE.md`, `.claude/rules` for Svelte and ultracite. The Svelte MCP server comes from `infra`. Applied on top of the `infra` template, `layout: parts` or `layout: single` respectively.
+Copier template for a SvelteKit frontend on Bun with Tailwind v4, biome or ESLint + Prettier and optional shadcn-svelte: SSR on Bun, a static SPA behind `serve.ts`, or a static SPA served by the backend api. A `frontend/` part or the whole project (`layout`), on top of `infra`.

-Runs in Docker, locally the same way as in production. `COMPOSE_PROFILES` in `.env` selects the services that run on this machine. `docker-compose.override.yml` 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 dev       # vite on the host
+make check
 ```
-
-`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.
