+# Repository Guidelines
+
+## Project Structure & Module Organization
+Backend Java sits in `src/main/java/de/assecutor/votianlt`; domain models stay in `model`, persistence logic in `repository`, services in `service`, MQTT integration under `mqtt`, and access control in `security`. Vaadin views and UI helpers live in `pages/view` and `pages/base`. TypeScript, styles, and theming live in `src/main/frontend` (leave `generated/` untouched). Shared configs and templates live in `src/main/resources`, while Vaadin bundle descriptors reside in `src/main/bundles`. Maven output lands in `target/`.
+
+## Build, Test, and Development Commands
+Use `./mvnw` for the Spring Boot dev server with frontend hot reload. Build production bits with `./mvnw -Pproduction package`. Run `./mvnw test` for unit checks and `./mvnw -Pintegration-test verify` when integration coverage is needed. After dependency changes, refresh Vaadin assets with `./mvnw vaadin:prepare-frontend`. Apply formatting via `./mvnw spotless:apply`.
+
+## Coding Style & Naming Conventions
+Spotless enforces Java 21 formatting using `eclipse-formatter.xml`; keep imports ordered and rely on Lombok already present. Classes remain PascalCase, Spring stereotypes end with `Service`, `Repository`, or `Config`, and Vaadin views retain the `*View` naming within `pages/view`. Frontend code follows the repo’s Prettier rules (`.prettierrc.json`); keep TypeScript modules co-located with their views, prefer camelCase for variables, and avoid checking in generated `.class` files.
+
+## Testing Guidelines
+Create tests under `src/test/java` mirroring the production package path. Name unit classes `*Test` and integration suites `*IT` so the failsafe profile picks them up. Lean on Spring Boot’s testing annotations for wiring, Mockito for isolates, and add Testcontainers when MongoDB or MQTT brokers are involved. Run `./mvnw test` before any push; trigger `./mvnw -Pintegration-test verify` for messaging, persistence, or security changes.
+
+## Commit & Pull Request Guidelines
+History currently uses brief German titles; shift to imperative, scoped summaries such as `feat: add PDF mailer` or `fix: guard MQTT reconnects`. Keep unrelated updates out of the same commit and exclude artifacts like `node_modules/` or `target/`. Pull requests should explain the motivation, link issues, note config or data-seed impacts, and attach screenshots or screencasts when Vaadin views change. List manual verification steps and flag any migrations or bundle adjustments for reviewers.
+
+## Security & Configuration Tips
+External service credentials for MongoDB, SMTP, and MQTT belong in environment variables or a developer-specific `application-local.properties` kept out of version control. Document default ports and topics when touching `MqttConfig` or Zeroconf publishers so ops can replicate environments. For two-factor flows, keep shared secrets in secure storage and avoid logging codes during development.
