+
+## Development server
+
+To start a local development server, run:
+
+```bash
+npm start
+# or
+ng serve
+```
+
+Once the server is running, open your browser and navigate to `http://localhost:4200/`.
+
+## Building
+
+To build the project for production:
+
+```bash
+npm run build
+# or
+ng build
+```
+
+This will compile your project and store the build artifacts in the `dist/market-backOffice/` directory.
+
+## Environment Configuration
+
+### Development (`src/environments/environment.ts`)
+```typescript
+export const environment = {
+  production: false,
+  apiUrl: 'http://localhost:3000/api',  // Local backend
+  useMockData: true  // Use mock data for development
+};
+```
+
+### Production (`src/environments/environment.production.ts`)
+```typescript
+export const environment = {
+  production: true,
+  apiUrl: 'https://api.dexarmarket.ru/api',  // Production backend
+  useMockData: false  // Use real API
+};
+```
+
+## Deployment
+
+### Prerequisites
+1. Node.js 18+ and npm installed
+2. Backend API running and accessible
+3. API URL configured in production environment
+
+### Build for Production
+```bash
+npm run build
+```
+
+### Deploy to Server
+1. Upload contents of `dist/market-backOffice/` to your web server
+2. Configure nginx or Apache to serve the files:
+
+**Nginx Example:**
+```nginx
+server {
+    listen 80;
+    server_name backoffice.dexarmarket.ru;
+    
+    root /var/www/backoffice;
+    index index.html;
+    
+    location / {
+        try_files $uri $uri/ /index.html;
+    }
+    
+    # Optional: Proxy API requests
+    location /api/ {
+        proxy_pass https://api.dexarmarket.ru/api/;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+}
+```
+
+3. Enable HTTPS with Let's Encrypt:
+```bash
+certbot --nginx -d backoffice.dexarmarket.ru
+```
+
+## Development Features
+
+### Auto-Save
+- Item editor auto-saves changes after 500ms of inactivity
+- Each field triggers individual PATCH requests
+- Visual feedback for save operations
+
+### Mock Data Mode
+- Enable with `useMockData: true` in environment
+- Simulates full API with realistic data
+- Useful for frontend development without backend
+
+### Material Design
+- Consistent UI with Angular Material
+- Themes can be customized in `src/styles.scss`
+- Responsive components for all screen sizes
+
+## Running unit tests
+
+To execute unit tests with [Vitest](https://vitest.dev/):
+
+```bash
+npm test
+# or
+ng test
+```
