- syncUsagesAfterEdit: use isLocked() instead of !isFinalized() to avoid
  syncing quizzes with started candidates (would have destroyed GivenAnswer records)
- syncToQuiz action: use isLocked() instead of hasStartedCandidates() to block
  syncing into finalized quizzes that have no started candidates
- QuestionBankService::syncToQuiz: remove internal flush(); callers now
  flush once (syncUsagesAfterEdit after the loop, syncToQuiz action after the call)
- QuizRepository::clearQuiz: delete BankQuestionUsage rows and reset
  finalized_at inside the transaction (previously orphaned usages blocked
  bank question reassignment; finalizedAt reset was a separate non-atomic flush)
- QuizController::finalizeQuiz: add flash when quiz is already finalized
- QuestionBankController::delete: block deletion when any usage references a locked quiz
- BankQuestion::__toString: remove dead null-coalescing on non-nullable string
- SeasonController::addBlankQuiz: align form field with UploadQuizFormType
  (add translation_domain: false, use translator for label)

+## Writing Style (Help Content & UI Text)
+
+When writing Dutch help content in `templates/backoffice/help/nl/`:
+
+- **No em-dashes** (—): use a comma or restructure the sentence instead.
+- **No semicolons** (;): use a comma. Semicolons are technically correct but read as AI-generated text.
+- **Natural Dutch**: write the way a person would explain it to a colleague, not in formal documentation style.
+- **Colons after bold labels** (e.g. `<strong>Label:</strong> description`) are fine and intentional.
+
 ## Notes for Future Work
 
 - The backoffice elimination logic is in `Controller/Backoffice/PrepareEliminationController.php`

 # Tijd voor de test
 
+![CI](https://github.com/MarijnDoeve/TijdVoorDeTest/actions/workflows/ci.yml/badge.svg)
+
+PHP/Symfony application for WIDM-style quiz management.
+Built with FrankenPHP, PostgreSQL, and Docker.

 ## Requirements
 
-### Maken van de test
+- Docker
+- [Just](https://just.systems) (`brew install just`)
 
-- WIDM-tests met een variabel aantal vragen.
+## Local development
-- Vragen in een vaste volgorde zijn samen één test (een vraag kan niet bij
-  meerdere tests horen).
-- Vragen hebben 2 of meer antwoordmogelijkheden. Slechts één antwoord is correct.
-- Meerdere test samen vormen een seizoen.
-- Een seizoen heeft één of geen actieve tests, als er een test actief is kan
-  uitsluitend die test gemaakt worden.
-- Kandidaten kunnen een test maximaal 1 keer invullen.
-- Vanaf het moment dat de kandidaat op start klikt na het intypen van hun naam
-  gaat de tijd lopen. Deze stopt na het aanklikken van een antwoord op de laatste
-  vraag van de test.
-- Achtergrondmuziek
 
-### Schermen kijken
+```bash
+just up        # Start PHP + PostgreSQL containers
+just migrate   # Run pending database migrations
+just fixtures  # Load dev fixtures (truncates first)
+```
 
-- Nadat een speler een test heeft gemaakt (of vooraf als de namen vooraf
+The app is available at **https://localhost** (self-signed cert — run
-  ingevoerd zijn) kunnen jokers toegekend worden aan de test van kandidaat. Een
+`just trust-cert` on macOS to trust it).
-  positief getal om antwoorden goed te rekenen, een negatief getal om
-  antwoorden fout te rekenen.
-- Vooraf kan gekozen worden hoe veel afvallers er zijn.
-- Bij het kijken naam rode en groene schermen wordt een naam ingevoerd. Er
-  wordt een rood of groen scherm getoond.
-- Spelers kunnen geforceerd op groen of rood gezet worden, deze worden dan niet
-  meegenomen in de berekening van de slechtste speler.
 
-### Statistieken
+### Useful commands
 
-TBD
+```bash
+just shell              # Shell inside the running PHP container
+just shell-run          # Shell in a fresh one-off container
+just stop               # Stop containers (keep volumes)
+just down               # Stop and remove containers
+just clean              # Nuclear: remove containers + volumes + generated files
+just exec <cmd>         # Run any command inside the PHP container
+```

+### Environment
 
-- Optie voor antwoord geven in twee klikken (selecteren en volgende).
+Copy `.env` and override locally via `.env.local` (not committed):
 
+| Variable       | Description                         |
+|----------------|-------------------------------------|
+| `APP_SECRET`   | Symfony app secret                  |
+| `DATABASE_URL` | PostgreSQL DSN (auto-set in Docker) |
+| `SENTRY_DSN`   | Sentry error tracking               |
+| `DEFAULT_URI`  | Base URL for CLI-generated links    |
+
+## Testing
+
+```bash
+just test                                   # Full PHPUnit suite
+just test tests/Path/To/TestFile.php        # Single file
+just test --coverage-html var/coverage      # HTML coverage report
+just reload-tests             # Drop/recreate test DB + migrate + test fixtures
+```
+
+Tests use a separate database configured via `.env.test`. The DAMA
+Doctrine bundle wraps each test in a transaction that is rolled back after.
+`just reload-tests` loads the `--group=test` fixtures; `just fixtures`
+loads the dev group and is unrelated to the test database.
+
+## Code quality
+
+All checks run in CI and must pass before merging.
+
+```bash
+just fix-cs              # Auto-fix PHP-CS-Fixer + Twig-CS-Fixer
+just phpstan             # PHPStan static analysis (level 8)
+just rector              # Apply Rector modernizations
+just rector --dry-run    # Preview Rector changes without applying
+```
+
+## Database
+
+```bash
+just migrate                      # Run pending migrations
+just fixtures                     # Load dev fixtures
+bin/console make:migration        # Generate a new migration (inside container)
+```
+
+Migrations live in `migrations/` (namespace `DoctrineMigrations`). Test
+fixtures are in `src/DataFixtures/` loaded with `--group=test`.
+
+## Translations
+
+```bash
+just translations    # Extract/update nl translation strings into translations/
+```
+
+## Contributing
+
+1. Create a branch from `main` — use a prefix like `feat/`, `fix/`,
+   or `docs/`.
+2. Open a pull request; CI must pass before merging.
+3. Install the pre-commit hook (see below) to catch issues before pushing.
+
+### Pre-commit hook
+
+A pre-commit hook lives in `.githooks/pre-commit`. Install it once after cloning:
+
+```bash
+just install-hooks
+```
+
+On every commit it runs automatically, **only on staged files**:
+
+| Staged file type        | Tools run                                                                    |
+|-------------------------|------------------------------------------------------------------------------|
+| `.php`                  | Rector → PHP-CS-Fixer (auto-fix + re-stage), then PHPStan (blocks on errors) |
+| `.twig`                 | Twig-CS-Fixer (auto-fix + re-stage)                                          |
+| Other (docs, config, …) | Nothing — commit proceeds immediately                                        |
+
+If the PHP container is not running, the hook falls back to
+`docker compose run --rm` so checks still execute. PHPUnit is not
+run in the hook; CI covers that.
+
+## Deployment
+
+Docker images are published to `ghcr.io/marijndoeve/tijdvoordetest`
+for each tagged release.
+
+### First-time setup
+
+1. Copy `compose.yaml` and `compose.prod.yaml` to your server.
+2. Create a `.env.prod.local` file with the required variables (see below).
+3. Start the stack — migrations run automatically on container start:
+
+```bash
+IMAGE_TAG=latest docker compose -f compose.yaml -f compose.prod.yaml up -d
+```
+
+### Updating to a new version
+
+```bash
+IMAGE_TAG=<tag> docker compose -f compose.yaml -f compose.prod.yaml pull
+IMAGE_TAG=<tag> docker compose -f compose.yaml -f compose.prod.yaml up -d
+```
+
+### Required environment variables
+
+| Variable                   | Description                                 |
+|----------------------------|---------------------------------------------|
+| `IMAGE_TAG`                | Image tag to run (e.g. `1.2.3` or `latest`) |
+| `APP_SECRET`               | Random secret string for Symfony            |
+| `CADDY_MERCURE_JWT_SECRET` | JWT secret for the Mercure hub              |
+| `POSTGRES_PASSWORD`        | PostgreSQL password                         |
+| `MAILER_DSN`               | Mailer transport DSN                        |
+| `MAILER_SENDER`            | From address for emails                     |
+| `SENTRY_DSN`               | Sentry project DSN (optional)               |
+
+The `compose.prod.yaml` configures Traefik labels for TLS termination at
+`tijdvoordetest.nl`. Adjust the `traefik` labels in that file if you're
+hosting on a different domain or using a different reverse proxy.
