+- pnpm (recommended) or npm
 
 ## Getting Started
+
 Instructions for installing dependencies and running the app locally.
 
 ```bash
-npm install
-npm run dev
+# Install dependencies
+pnpm install
+
+# Run in development mode
+pnpm run dev
+
+# Build for production
+pnpm run build
+
+# Start production server
+pnpm run start
 ```

+### Folder Descriptions
+
+| Folder | Description |
+|--------|-------------|
+| `config/` | Environment configuration, app settings, and external service configs |
+| `constants/` | Static values, HTTP status codes, error messages, and app-wide constants |
+| `middleware/` | Request processing middleware (auth, logging, validation, etc.) |
+| `services/` | Business logic layer with reusable service modules |
+| `shared/` | Cross-cutting utilities shared across the application |
+| `types/` | TypeScript interfaces, types, and type guards |
+| `utils/` | Helper functions and utility modules |
+
 ## Scripts
-Explanation of the main NPM scripts for development.
 
-dev - Starts the app in development mode with live reloading
-build - Compiles TypeScript to JavaScript
-start - Runs the compiled app
-test - Runs unit tests
-Deployment
-Notes on how to deploy the app to production.
+| Script | Description |
+|--------|-------------|
+| `dev` | Starts the app in development mode with live reloading |
+| `build` | Compiles TypeScript to JavaScript (CJS and ESM) |
+| `start` | Runs the compiled app |
+| `test` | Runs unit tests |
+| `test:cov` | Runs tests with coverage report |
+| `lint` | Runs ESLint to check and fix code style |
+| `format` | Formats code using Prettier |
+
+## Path Aliases
+
+The project uses path aliases for cleaner imports:
+
+```typescript
+import { config } from '@/config';
+import { HTTP_STATUS } from '@/constants';
+import { getCurrentTimestamp } from '@/utils';
+```
+
+## Docker
+
+Build and run the application using Docker:
+
+```bash
+docker build -t template-node-typescript .
+docker run -p 8080:8080 template-node-typescript
+```
+
