+**You have reached the `debian12` branch.**
 
-A small full‑stack system to log in, view available items, reserve them for a time window, and manage personal loans.
+Here you will find the source code of exactly the application that I have hosted.
 
-- Frontend: React + TypeScript + Vite + Tailwind CSS
-- Backend: Node.js + Express + MySQL + JWT (jose)
-- Orchestration: Docker Compose (backend + MySQL)

-- Docs: [docs/](docs)
-  - API docs (see below): [docs/backend_API_docs/README.md](docs/backend_API_docs/README.md)
-
-## 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).
