 ## General information
 
-When you look at my backend folder and file structure, you can see that I have two files called `API`. The first file called `api.js` is for my web frontend, because this file works together with my JWT token service.

+But first you have to get an API Key. You can get the API key from my admin dashboard. When you don't have any access to my admin dashboard, please contact your administrator or me.

+- Frontend: `https://insta.the1s.de`
+- Backend: `https://backend.insta.the1s.de`
+- Base path for this API: `https://backend.insta.the1s.de/apiV2`
+
+You can see the status of this and all my other services at `https://status.the1s.de`.
+
+_I have also build a [fallback page](https://git.the1s.de/theis.gaedigk/fallback-page). When only the application is down, you will see a friendly message and a link to the status page. (Only if the server is not down)_

 ## Authentication
 
-All endpoints require the Admin API key (`ADMIN_ID`) as a URL parameter.
+All endpoints require an API key as a path parameter named `:key`.
 
-Example: `/apiV2/items/{ADMIN_ID}`
+Example: `/apiV2/items/:key`
+
+If the key is missing or invalid, the API responds with `401 Unauthorized`.

+
+## Features (high‑level)
+
+- Auth via JWT (login -> token cookie) using the backend route in [backend/routes/api.js](backend/routes/api.js).
+- After login, the app loads items, loans, and user loans and keeps them in localStorage.
+- Choose a date range to fetch borrowable items, select items, and create a loan.
+- Manage personal loans list (and delete a loan).
+
+Key frontend utilities:
+
+- [`utils.fetchData.fetchAllData`](frontend/src/utils/fetchData.ts): loads items, loans, and user loans after login.
+- [`utils.fetchData.getBorrowableItems`](frontend/src/utils/fetchData.ts): fetches borrowable items for the selected time range.
+- [`utils.userHandler.createLoan`](frontend/src/utils/userHandler.ts): creates a new loan for selected items.
+- [`utils.userHandler.handleDeleteLoan`](frontend/src/utils/userHandler.ts): deletes a loan and syncs local state.
+- [`utils.toastify.myToast`](frontend/src/utils/toastify.ts): toast notifications.
+
+UI flow (main screens):
+
+- Period selection: [frontend/src/components/Form1.tsx](frontend/src/components/Form1.tsx)
+- Borrowable items + selection: [frontend/src/components/Form2.tsx](frontend/src/components/Form2.tsx)
+- User loans table: [frontend/src/components/Form4.tsx](frontend/src/components/Form4.tsx)
+
+## Development
+
+- Scripts: see [frontend/package.json](frontend/package.json) and [backend/package.json](backend/package.json)
+  - Frontend: `npm run dev`, `npm run build`, `npm run preview`, `npm run lint`
+  - Backend: `npm start`
+- Linting: ESLint configured via [frontend/eslint.config.js](frontend/eslint.config.js)
+- TypeScript configs: [frontend/tsconfig.app.json](frontend/tsconfig.app.json), [frontend/tsconfig.node.json](frontend/tsconfig.node.json)
+
+## Configuration notes
+
+- Vite/Tailwind integration via [frontend/vite.config.ts](frontend/vite.config.ts) and `@tailwindcss/vite`; CSS entry uses `@import "tailwindcss"` in [frontend/src/index.css](frontend/src/index.css).
+- Toasts wired in [frontend/src/main.tsx](frontend/src/main.tsx) with `react-toastify`.
+- Local state is stored in `localStorage` keys: `allItems`, `allLoans`, `userLoans`, `borrowableItems`. Cross‑component updates are signaled via window events from [`utils.fetchData`](frontend/src/utils/fetchData.ts).
