+> **Note** For production, check the [prod branch](https://git.the1s.de/theis.gaedigk/ca-lose/src/branch/prod/) which contains an VPN git submodule of wg-easy to run the app securely on a private network. It also contains a dnsmasq container to resolve the backend service name from the frontend container. The main branch is meant for local development and testing, so it doesn't include those components to keep things simple.

+
+## Project Structure
+
+- Frontend (Vite + React + Tailwind + MUI): [frontend](frontend)
+- Backend (Express): [backend](backend)
+- Database schema: [backend/scheme.sql](backend/scheme.sql)
+- Docker compose stack: [docker-compose.yml](docker-compose.yml)
+
+## Quick Start (Docker)
+
+1. Set the database password env var used by Docker Compose:
+
+```bash
+DB_PASSWORD=your_password
+```
+
+2. Start MySQL and the backend:
+
+```bash
+docker compose up -d
+```
+
+Notes:
+
+- The frontend service is commented out in [docker-compose.yml](docker-compose.yml). If you want the frontend container, uncomment that block and rebuild.
+- The frontend container uses Nginx and proxies /backend to the backend service (see [frontend/nginx.conf](frontend/nginx.conf)).
+- In order to use the database properly, run the scheme and create some users in the users table.
+
+## Local Development
+
+### Backend
+
+1. Create a .env file in the backend folder with:
+
+```env
+PORT=8004
+DB_HOST=127.0.0.1
+DB_USER=root
+DB_PASSWORD=your_password
+DB_NAME=ca_lose
+```
+
+2. Install deps and run:
+
+```bash
+cd backend
+npm install
+node server.js
+```
+
+Backend listens on http://localhost:8004 and exposes routes under /default.
+
+### Frontend
+
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+Vite runs the app on the default dev port and talks to the backend using the API helpers in [frontend/src/utils/api](frontend/src/utils/api).
+
+## API Endpoints
+
+- GET /default/users
+- GET /default/confirm-user?username={name}
+- POST /default/new-entry?username={name}
+
+## Database Notes
+
+- The base users table is defined in [backend/scheme.sql](backend/scheme.sql).
+- Per-user ticket tables are created on demand by the backend (see [backend/routes/default/frontend.data.js](backend/routes/default/frontend.data.js)).
