-Here you will find the source code of exactly the application that I have hosted.
+A small full‑stack system to log in, view available items, reserve them for a time window, and manage personal loans.

-The main branch or the branch that I am developing on, is the `dev` branch.
+- Frontend: React + TypeScript + Vite + Tailwind CSS
+- Backend: Node.js + Express + MySQL + JWT (jose)
+- Orchestration: Docker Compose (backend + MySQL)

+  - 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).

+# How to use Atoms
+Atoms are the fundamental building blocks of state management in this system. They represent individual pieces of state that can be shared and manipulated across different components.
+
+You can also name it global state.
+
+## Creating an Atom
+to create an atom you have to declare an atom like this:
+
+```ts
+import { atom } from 'jotai';
+
+export const NAME_OF_YOUR_ATOM = atom<type_of_your_atom>(initial_value);
+```
+
+In this project we declare all atoms in the `States/Atoms.tsx`file. Which you can find above this README file.
+
+## Using an Atom
+To use an atom in your component, you can use the `useAtom` hook provided by Jotai. Here's an example of how to use an atom in a React component:
+
+```tsx
+import { useAtom } from 'jotai';
+import { NAME_OF_YOUR_ATOM } from '@/States/Atoms';
+
+const MyComponent = () => {
+  const [value, setValue] = useAtom(NAME_OF_YOUR_ATOM);
+
+  return (
+    <div>
+      <p>Current value: {value}</p>
+      <button onClick={() => setValue(newValue)}>Update Value</button>
+    </div>
+  );
+};
+```
+
+As you can see, you can use `useAtom` like `useState` but the state is global. In this example `value` is the current state of the atom, and `setValue` is a function to update the state, which is also known as the setter function.
