+## Stack
+- Vite + React 18 with TypeScript.
+- `@tanstack/react-query` for data fetching and caching.
+- shadcn/ui primitives (button, card, tabs, dialog, etc.) with Tailwind CSS.
+- Sonner & Toast UI for notifications, Markdown rendering, RTL layout, and Persian-digit helpers.
+
+## Development
+
+### Install dependencies
+```bash
+npm install
+```
+
+### Run dev server
+```bash
+npm run dev -- --host
+```
+
+### Production build
+```bash
+npm run build
+```
+
+## Features
+- **Public site**: homepage, events list/detail, blog list, auth flows, profile, payments.
+- **Admin dashboard**: staff-only portal with vertical tabs, user filtering, event filtering, popup detail with registrations/payments, and inline event editing/deletion.
+- **Utils**: Persian digit formatting, price conversion (Rial → Toman), shared API client with JWT token refresh handling, and helper components (scroll area, table, dialog).
+
+## Testing & linting
+```bash
+npm run lint
+```
+
+JavaScript/TypeScript linting is configured through ESLint + `typescript-eslint`. Run lint before commits to keep code healthy.
