-### Project Structure (abridged)
+## Getting Started
+install bun
+```bash
+$ bun run dev
 ```
-src/
-	api/              # External data fetchers
-	components/       # UI building blocks (Cards, Timetable, Weather, Terminal, etc.)
-	store/            # Zustand stores encapsulating fetch + state
-	types/            # Type definitions for external data
-pipeline/
-	create-git-hash-html.sh  # Injects current commit hash into dist
-Dockerfile          # Nginx static hosting
-docker-compose.yml  # Example runtime service definition
-```
-
-### Environment Configuration
-Create a `.env` (or `.env.local`) for Vite with the following (only what you need):
-```
-VITE_FLATTASTIC_API_KEY=your_flatastic_api_key
-# (Planned) VITE_HOME_ASSISTANT_TOKEN=your_long_lived_token  # NOTE: currently hardcoded – see Security section
-```
-
-Vite automatically exposes variables prefixed with `VITE_` to the client bundle. Do NOT place secrets without that prefix – but remember: anything in the client bundle is public. For sensitive data consider a tiny proxy backend instead of calling APIs directly from the browser.
-
-### Security Notice
-`src/api/homeAssistant.ts` currently contains a hard‑coded long‑lived Home Assistant token. This should be refactored before any public deployment:
-1. Remove the literal token from the repository.
-2. Load it via environment variable during build (`import.meta.env.VITE_HOME_ASSISTANT_TOKEN`) OR
-3. Prefer a minimal server proxy so the token never ships to the browser.
-
-### Development
-Install dependencies (Bun is inferred from `bun.lock`, but npm/pnpm/yarn also work).
-```
-bun install
-```
-Run the dev server (HTTPS support possible with `vite-plugin-mkcert` if certificates are trusted):
-```
-bun run dev
-```
-Open: http://localhost:5173
-
-### Lint & Format
-```
-bun run lint
-```
-Optionally run Biome (if desired):
-```
-npx biome check --apply .
-```
-
-### Build
-```
-bun run build
-```
-Outputs production bundle to `dist/`.
-
-### Docker Image
-Build locally:
-```
-docker build -t monitor-im-flur:local .
-```
-Run:
-```
-docker run --rm -p 9123:80 monitor-im-flur:local
-```
-Or use compose (uses published image):
-```
-docker compose up -d
-```
-Visit: http://localhost:9123
-
-### Data Sources
-* KVV Departures: Public endpoint (JSON) for stop IDs 7000044 / 7000045.
-* Weather: Open‑Meteo forecast API (lat 49.0094, lon 8.4044, Europe/Berlin TZ).
-* Flatastic: Auth via `x-api-key` (user provided).
-* Home Assistant: Long‑lived bearer token (refactor recommended).
-
-### Adding a New Card
-1. Create a directory under `src/components/<NewCard>/` with `NewCard.tsx` & optional `style.module.css`.
-2. Wrap content with existing `Card` component (`icon` + `name` props).
-3. Register inside `Dashboard.tsx` where layout lives (using `CardColumn` / `CardRow`).
-
-### State Management Notes
-All data fetching is encapsulated inside zustand store `fetch` methods invoked on an interval within the respective components. Consider centralizing polling or using React Query if complexity grows.
