```

## 📁 .env File Setup (Recommended)

Create a `.env` file in your project root:

```env
# .env file for ADPA v2.1.3
# IMPORTANT: Add .env to your .gitignore file!

## 🔍 Verification Commands

### **Check AI Provider Configuration**
```bash
# Test your AI provider setup
npm run requirements-gathering-agent --status
```

### **Check Confluence Integration**
```bash
# Initialize Confluence configuration
npm run confluence:init

# Check Confluence status
npm run confluence:status

# Test Confluence connection
npm run confluence:test
```

## ⚠️ Security Best Practices

### **1. Environment Variable Security**
- ✅ Never commit `.env` files to version control
- ✅ Add `.env` to your `.gitignore` file
- ✅ Use different API tokens for different environments
- ✅ Regularly rotate API tokens

### **2. API Token Management**
- ✅ Use descriptive names for API tokens
- ✅ Set appropriate expiration dates
- ✅ Monitor token usage in provider dashboards
- ✅ Revoke unused tokens immediately

### **3. Confluence-Specific Security**
- ✅ Use dedicated API tokens for ADPA
- ✅ Limit token permissions to required scopes
- ✅ Monitor Confluence activity logs
- ✅ Use space-specific permissions when possible

## 🛠️ Troubleshooting

### **Common Issues**

1. **"API token not found" errors**
   ```bash
   # Check if environment variables are set
   echo $CONFLUENCE_API_TOKEN    # Linux/macOS
   echo $env:CONFLUENCE_API_TOKEN # Windows PowerShell
   ```

2. **"Connection failed" errors**
   ```bash
   # Test Confluence connection
   npm run confluence:test
   ```

3. **"Invalid space key" errors**
   ```bash
   # Check Confluence configuration
   npm run confluence:status
   ```

### **Debug Commands**
```bash
# Show detailed configuration status
node dist/cli.js --status

# Show Confluence integration status
node dist/cli.js confluence status

# Test with verbose output
node dist/cli.js confluence test --verbose
```

## 📊 Environment Variable Priority

ADPA uses the following priority order for configuration:

1. **Environment Variables** (highest priority)
2. **config-rga.json** (medium priority)
3. **Default values** (lowest priority)

This means environment variables will always override configuration file settings.

## 🎯 Quick Setup Checklist

- [ ] Choose and configure one AI provider
- [ ] Set required environment variables
- [ ] Create `.env` file (optional but recommended)
- [ ] Add `.env` to `.gitignore`
- [ ] Test AI provider: `npm run requirements-gathering-agent --status`
- [ ] Initialize Confluence: `npm run confluence:init`
- [ ] Configure Confluence settings in `config-rga.json`
- [ ] Test Confluence: `npm run confluence:test`
- [ ] Generate and publish documents: `npm run confluence:publish`

## 🚀 Ready to Go!

Once you have your environment variables configured:

1. **Generate documents**: `node dist/cli.js --generate-all`
2. **Publish to Confluence**: `npm run confluence:publish`
3. **Check status anytime**: `npm run confluence:status`
