+# Deploying ht_booking (Tenis Rajec)
+
+This app ships as a single Docker container that runs behind your existing
+shared **Caddy** reverse proxy. Caddy terminates HTTPS; the app container has
+no host ports and is reachable only through Caddy. The SQLite database lives
+on a Docker volume so it survives rebuilds and restarts.
+
+```
+Internet ──▶ Caddy (:80/:443, HTTPS)
+                 │  reverse_proxy ht-booking:5150   (over tenisrajec-net)
+                 ▼
+           ht-booking container ──▶ /usr/app/data/production.sqlite
+                                          (Docker volume: ht_booking_data)
+```
+
+Files in this repo that drive the deployment:
+
+| File | Role |
+|---|---|
+| `Dockerfile` | 3-stage build: CSS → Rust binary → slim runtime image |
+| `docker-compose.prod.yml` | the app service, volume, network |
+| `Caddyfile` | the site's reverse-proxy block (imported by central Caddy) |
+| `config/production.yaml` | Loco production config (no secrets) |
+| `.env.production.example` | template for secrets — copy to `.env.production` |
+| `Makefile` | `make up` / `down` / `logs` / `restart` |
+
+---
+
+## Prerequisites
+
+- The server already runs the shared Caddy stack (`docker-compose.caddy.yml`).
+- Docker + `docker-compose` are installed (they already are — Caddy uses them).
+- You can edit DNS for `tenisrajec.sk`.
+
+---
+
+## One-time setup
+
+### 1. Point DNS at the server
+
+Create DNS **A records** so both names resolve to the server's public IP:
+
+```
+tenisrajec.sk        A    <server-ip>
+www.tenisrajec.sk    A    <server-ip>
+```
+
+Do this first — Caddy needs the domain to resolve to obtain the TLS
+certificate. Propagation can take a while.
+
+### 2. Clone the repo onto the server
+
+```sh
+cd ~
+git clone <your-git-remote-url> ht_booking
+cd ht_booking
+```
+
+(The rest of this guide assumes the repo is at `~/ht_booking`.)
+
+### 3. Create the shared network
+
+The app and Caddy talk over a dedicated Docker network — same pattern as your
+other projects (`biomed-net`, `farmeris-net`, …):
+
+```sh
+docker network create tenisrajec-net \
+  --driver bridge --opt com.docker.network.driver.mtu=1450
+```
+
+### 4. Create the secrets file
+
+```sh
+cp .env.production.example .env.production
+openssl rand -hex 32          # copy the output into JWT_SECRET
+nano .env.production
+```
+
+Fill in:
+- `JWT_SECRET` — paste the `openssl` output (**required** — the app won't start without it).
+- `ADMIN_EMAIL` / `ADMIN_PASSWORD` — the single admin login, seeded on first boot.
+
+`.env.production` is gitignored — it stays only on the server.
+
+### 5. Hook the site into the central Caddy
+
+Caddy must (a) import this site's `Caddyfile` and (b) join `tenisrajec-net`.
+
+**a.** Add one line to the central `~/Caddyfile`:
+
+```
+import /etc/caddy/Caddyfile_tenisrajec
+```
+
+**b.** In `~/docker-compose.caddy.yml`, under the `caddy` service add the
+Caddyfile mount to `volumes:` …
+
+```yaml
+      - ./ht_booking/Caddyfile:/etc/caddy/Caddyfile_tenisrajec
+```
+
+… add the network to the `caddy` service's `networks:` list …
+
+```yaml
+    networks:
+      - vonavucke-net
+      - biomed-net
+      - gitea-net
+      - mqtt-net
+      - farmeris-net
+      - tenisrajec-net          # <-- add
+```
+
+… and declare it in the top-level `networks:` block:
+
+```yaml
+  tenisrajec-net:
+    external: true
+    driver: bridge
+    driver_opts:
+      com.docker.network.driver.mtu: 1450
+```
+
+**c.** Recreate Caddy so it picks up the new mount and network:
+
+```sh
+cd ~
+docker-compose -f docker-compose.caddy.yml up -d
+```
+
+### 6. Build and start the app
+
+```sh
+cd ~/ht_booking
+make up
+```
+
+The first build takes a few minutes (it compiles the Rust release binary).
+On first boot the app creates the SQLite database, runs all migrations, and
+seeds the admin account and a default court — automatically.
+
+### 7. Verify
+
+```sh
+make logs        # look for "listening on http://0.0.0.0:5150"
+make ps          # STATUS should become "healthy"
+```
+
+Then open <https://tenisrajec.sk> — Caddy will have issued the certificate.
+
+---
+
+## Updating after code changes
+
+```sh
+cd ~/ht_booking
+git pull
+make restart
+```
+
+`make restart` rebuilds the image and recreates the container. The database
+volume is untouched, so all bookings are preserved. Migrations for any new
+schema run automatically on boot.
+
+> If you changed templates/CSS, the image rebuilds `app.css` itself — you do
+> not need to run `npm run build:css` on the server.
+
+---
+
+## Backups
+
+The whole database is one SQLite file inside the `ht_booking_data` volume.
+Copy it out at any time:
+
+```sh
+docker cp ht-booking:/usr/app/data/production.sqlite ./backup-$(date +%F).sqlite
+```
+
+Restore by stopping the app, copying a file back, and starting it:
+
+```sh
+make down
+docker cp ./backup-2026-05-16.sqlite ht-booking:/usr/app/data/production.sqlite
+make up
+```
+
+A nightly `cron` job running that `docker cp` into a backed-up directory is
+enough for this site.
+
+---
+
+## Troubleshooting
+
+| Symptom | Cause / fix |
+|---|---|
+| App exits immediately, logs mention `JWT_SECRET` / config | `JWT_SECRET` is empty in `.env.production`. Set it, `make restart`. |
+| `502 Bad Gateway` from Caddy | App not up yet, or Caddy didn't join `tenisrajec-net`. Check `make ps` and step 5b. |
+| Caddy can't get a certificate | DNS not pointing at the server yet, or ports 80/443 blocked. |
+| `network tenisrajec-net not found` | Run step 3 before `make up` / recreating Caddy. |
+| Need a shell in the container | `docker exec -it ht-booking bash` |
+
+The app listens on `5150` **inside** its container only — it is intentionally
+not published to the host. All traffic goes through Caddy.

 ## Quick Start
@@ -48,6 +49,40 @@ compilation: debug
 listening on http://localhost:5150
 ```
 
+## Styling (CSS build)
+
+The UI uses Tailwind CSS + daisyUI. Rather than the render-blocking Tailwind
+Play CDN, the stylesheet is compiled ahead of time into a purged, minified
+bundle at `assets/static/css/app.css` (served at `/static/css/app.css`).
+
+One-time setup:
+
+```sh
+npm install
+```
+
+Rebuild the bundle after changing any class names in `assets/views/**/*.html`
+or the theme config:
+
+```sh
+npm run build:css       # one-off, minified
+npm run watch:css       # rebuild on save while developing templates
+```
+
+`assets/static/css/app.css` is committed, so a deploy needs no Node step — but
+remember to rebuild and commit it whenever the templates change. The Tailwind
+source lives in `assets/css/tailwind.css`; theme config is `tailwind.config.js`.
+
+## Deployment
+
+Production runs as a single Docker container behind a Caddy reverse proxy.
+See **[DEPLOY.md](DEPLOY.md)** for the full first-time setup. After that, a
+deploy is just:
+
+```sh
+git pull && make restart
+```
+
 ## Full Stack Serving
