+# Orderly Authentication Demo
+
+This repository contains a full-stack authentication and authorization playground
+built with a Node.js/Express API, MongoDB, and a React client. It now also
+includes a cross-platform Electron desktop shell and a React Native (Expo)
+mobile app that consume the same endpoints as the web front-end without
+duplicating UI logic.
+
+## Projects
+
+- `server/` – Express API with JWT auth, refresh tokens, MFA, RBAC, and audit logging.
+- `client/` – React + Vite SPA used as the primary reference implementation.
+- `desktop/` – Electron + React desktop application targeting Windows, macOS, and Linux.
+- `mobile/` – React Native (Expo) client for iOS, Android, and the web.
+
+## Desktop application
+
+1. Install dependencies and start the desktop shell in development mode:
+
+   ```bash
+   cd desktop
+   npm install
+   npm run dev
+   ```
+
+   The script runs the Vite dev server on port `5173` and launches Electron once
+   the renderer is ready.
+
+2. Copy `.env.example` to `.env` and adjust `VITE_API_URL` so the desktop client
+   can talk to your API server. Packaged builds will fall back to the preload
+   bridge (`window.orderlyDesktop.apiBaseUrl`).
+
+3. Build installers for macOS, Windows, and Linux:
+
+   ```bash
+   npm run build
+   ```
+
+   Packages are emitted to `desktop/release/` via `electron-builder` (`dmg`,
+   `nsis`, `AppImage`, `deb`).
+
+The renderer reuses the same auth flows and protected routes exported from the
+web SPA so both surfaces stay aligned feature-for-feature.
+
+## Mobile application (React Native / Expo)
+
+1. Install dependencies and copy the example environment file:
+
+   ```bash
+   cd mobile
+   npm install
+   cp .env.example .env
+   ```
+
+   Ensure `EXPO_PUBLIC_API_URL` points at your API server (defaults to
+   `http://localhost:3000/api`).
+
+2. Start the Expo dev server:
+
+   ```bash
+   npm run start
+   ```
+
+   Use the Expo interface to launch iOS simulators, Android emulators/devices,
+   or the web preview. Convenience scripts `npm run ios`, `npm run android`,
+   and `npm run web` are also available.
+
+The mobile app mirrors the browser experience: it persists tokens in
+`AsyncStorage`, reuses the API client with refresh-token retries, and exposes
+profile, accounts, sales, and admin screens gated by the same permissions used
+elsewhere in the project.

+# Orderly Desktop
+
+Electron + React desktop client that wraps the existing web SPA codebase.
+
+The renderer imports the routes, auth context, and UI components directly from
+`../client`, so both experiences stay in lockstep with zero duplication. Runtime
+configuration comes from the regular Vite env vars and, when packaged, the
+`window.orderlyDesktop.apiBaseUrl` bridge injected by the preload script.
+
+## Getting started
+
+```bash
+cd desktop
+npm install
+npm run dev
+```
+
+The development server starts Vite on port 5173 and spawns Electron once the
+renderer bundle is ready.
+
+Create a `.env` file based on `.env.example` to point the desktop shell at your
+API server (falls back to `http://localhost:3000/api`).
+
+## Packaging
+
+To create distributable binaries for macOS, Windows, and Linux, run:
+
+```bash
+npm run build
+```
+
+Artifacts are written to the `release/` directory using `electron-builder`
+targets (`dmg`, `nsis`, `AppImage`, `deb`).

+# Orderly Mobile (React Native)
+
+A cross-platform React Native (Expo) client that mirrors the existing web dashboard. It
+shares the authentication flows (email/password + MFA) and consumes the same REST API
+endpoints for profile data, accounts invoices, sales orders, and admin user management.
+
+## Getting started
+
+```bash
+cd orderly/mobile
+npm install
+```
+
+Create a `.env` file based on `.env.example` and point `EXPO_PUBLIC_API_URL` at your API
+instance (the default assumes the Node server is running on `http://localhost:3000/api`).
+
+```bash
+cp .env.example .env
+```
+
+Then launch the Expo development server:
+
+```bash
+npm run start
+```
+
+From the Expo CLI UI you can open the native app on:
+
+- **iOS** simulators (or a physical device via the Expo Go app)
+- **Android** emulators/devices
+- **Web** (for quick inspection in a browser)
+
+For convenience there are shortcut scripts:
+
+```bash
+npm run ios    # iOS simulator
+npm run android
+npm run web
+```
+
+## How it works
+
+- `src/context/AuthContext.js` mirrors the web client's auth provider, storing the access
+  token + user profile in `AsyncStorage` and attaching the access token to the shared Axios
+  instance. The refresh-token interceptor matches the browser behaviour so sessions stay
+  alive as long as the refresh cookie is valid.
+- `src/navigation/RootNavigator.jsx` toggles between the login stack and the authenticated
+  tab navigator. Tabs expose profile, accounts, sales, and admin screens, all guarded by
+  the same permission checks used on the web.
+- Each screen hits the corresponding API endpoint and renders either the JSON payload or a
+  friendly permission error when the user lacks access.
+
+## Linting
+
+You can run Expo's lint rules with:
+
+```bash
+npm run lint
+```
