+# Database Configuration Setup
+
+## Overview
+Database credentials are stored in a separate configuration file (`db.config.js`) that is **NOT committed to GitHub** for security reasons.
+
+## Files
+
+### 1. `db.config.example.js` (Committed to Git)
+Template file showing the required configuration structure.
+
+### 2. `db.config.js` (NOT Committed - in .gitignore)
+Contains actual database credentials. This file must be created manually.
+
+### 3. `.gitignore`
+Ensures `db.config.js` is never committed to the repository.
+
+## Setup Instructions
+
+### For Local Development
+
+1. **Copy the example file:**
+   ```bash
+   cp db.config.example.js db.config.js
+   ```
+
+2. **Edit `db.config.js` with your credentials:**
+   ```javascript
+   module.exports = {
+       host: 'localhost',  // or your database host
+       user: 'your_username',
+       password: 'your_password',
+       database: 'appgconnect5_db',
+       waitForConnections: true,
+       connectionLimit: 10,
+       queueLimit: 0
+   };
+   ```
+
+3. **Start the server:**
+   ```bash
+   npm start
+   ```
+
+### For Production Deployment
+
+1. **Pull the latest code on your server:**
+   ```bash
+   git pull origin main
+   ```
+
+2. **Create `db.config.js` on the production server:**
+   ```bash
+   nano db.config.js
+   # or
+   vi db.config.js
+   ```
+
+3. **Add your production database credentials:**
+   ```javascript
+   module.exports = {
+       host: 'your-production-db-host.com',
+       user: 'production_user',
+       password: 'secure_production_password',
+       database: 'appgconnect5_db',
+       waitForConnections: true,
+       connectionLimit: 10,
+       queueLimit: 0
+   };
+   ```
+
+4. **Save and restart the server:**
+   ```bash
+   pm2 restart connect5
+   # or your restart command
+   ```
+
+## Security Features
+
+✅ **Credentials not in git** - `db.config.js` is in `.gitignore`  
+✅ **Template provided** - `db.config.example.js` shows the structure  
+✅ **Comments in code** - Clear instructions in `database.js`  
+✅ **Separate config** - Easy to update without touching main code  
+
+## Troubleshooting
+
+### Error: Cannot find module './db.config.js'
+
+**Solution:** You need to create the `db.config.js` file:
+```bash
+cp db.config.example.js db.config.js
+# Then edit with your credentials
+```
+
+### Error: Access denied for user
+
+**Solution:** Check your credentials in `db.config.js`:
+- Verify username
+- Verify password  
+- Check host address
+- Ensure user has proper permissions
+
+### Connection timeout
+
+**Solution:**
+- Check if MySQL server is running
+- Verify firewall allows connection
+- Check host address is correct
+
+## Important Notes
+
+⚠️ **NEVER commit `db.config.js` to git**  
+⚠️ **Keep production credentials secure**  
+⚠️ **Use different credentials for dev/prod**  
+⚠️ **Regularly rotate passwords**
