+# Environment Configuration Guide
+
+This project supports multiple environment configurations for local development, development server, testing, and UAT environments.
+
+## Environment Files
+
+- `.env.example` - Template file with all available environment variables
+- `.env.local` - Local development environment (default)
+- `.env.dev` - Development server environment
+- `.env.test` - Test/QA environment
+- `.env.uat` - User Acceptance Testing environment
+
+## Setup Instructions
+
+1. **Copy the example file to create your environment file:**
+   ```bash
+   cp .env.example .env.local
+   ```
+
+2. **Update the API URLs and configuration in your chosen environment file** with actual server URLs.
+
+3. **Commit only `.env.example` to version control** - all `.env.*` files are gitignored.
+
+## Running the Application
+
+### Development Servers (Local)
+
+- **Local Development (Port 5174):**
+  ```bash
+  npm run dev:local
+  ```
+  or simply:
+  ```bash
+  npm run dev
+  ```
+
+- **Dev Environment (Port 5174):**
+  ```bash
+  npm run dev:dev
+  ```
+
+- **Test Environment (Port 5175):**
+  ```bash
+  npm run dev:test
+  ```
+
+- **UAT Environment (Port 5176):**
+  ```bash
+  npm run dev:uat
+  ```
+
+### Building for Production
+
+- **Build for Local:**
+  ```bash
+  npm run build:local
+  ```
+
+- **Build for Dev:**
+  ```bash
+  npm run build:dev
+  ```
+
+- **Build for Test:**
+  ```bash
+  npm run build:test
+  ```
+
+- **Build for UAT:**
+  ```bash
+  npm run build:uat
+  ```
+
+### Preview Production Build
+
+- **Preview Local Build:**
+  ```bash
+  npm run preview:local
+  ```
+
+- **Preview Dev Build:**
+  ```bash
+  npm run preview:dev
+  ```
+
+- **Preview Test Build:**
+  ```bash
+  npm run preview:test
+  ```
+
+- **Preview UAT Build:**
+  ```bash
+  npm run preview:uat
+  ```
+
+## Environment Variables
+
+Each environment file contains these variables:
+
+- `VITE_API_URL` - Backend API endpoint URL
+- `VITE_ENV` - Environment name (local, dev, test, uat)
+- `VITE_APP_NAME` - Application name/title
+
+You can add more variables as needed. They should be prefixed with `VITE_` to be accessible in the browser.
+
+## Accessing Environment Variables in Code
+
+Access environment variables in your React components:
+
+```typescript
+const apiUrl = import.meta.env.VITE_API_URL
+const environment = import.meta.env.VITE_ENV
+const appName = import.meta.env.VITE_APP_NAME
+```
+
+Example in ApiClient.ts:
+```typescript
+const baseURL = import.meta.env.VITE_API_URL
+```
+
+## Development Ports
+
+Each environment runs on a different port to allow running multiple instances:
+
+| Environment | Port  |
+|------------|-------|
+| Local      | 5174  |
+| Dev        | 5174  |
+| Test       | 5175  |
+| UAT        | 5176  |
+
+## Notes
+
+- All environment files except `.env.example` are gitignored
+- Never commit sensitive API keys or credentials to version control
+- Use `.env.example` as a template for new environment setup
+- Vite automatically loads the correct `.env.*` file based on the mode flag
