bind_ip = "0.0.0.0"
listenport = "8080"
storage_path = "/data/uploads"
hmac_secret = "your-secret-key-here"
max_upload_size = "100MB"

[security]
require_hmac = true
```

### Mobile-Optimized Configuration
```toml
[server]
bind_ip = "0.0.0.0"
listenport = "8080"
storage_path = "./uploads"

[network_resilience]
enable_network_resilience = true
grace_period_hours = 72
detect_network_changes = true

[client_network_support]
enable_client_network_support = true
mobile_grace_hours = 72
desktop_grace_hours = 48
```

## 🔧 **Quick Configuration Options**

### Using Pre-Built Binaries

If you cloned the repository, you'll find ready-to-use binaries in the `builds/` directory:

```bash
# List available architectures
ls builds/
# hmac-file-server-darwin-amd64    # macOS Intel
# hmac-file-server-darwin-arm64    # macOS Apple Silicon  
# hmac-file-server-linux-386       # Linux 32-bit
# hmac-file-server-linux-amd64     # Linux 64-bit (most common)
# hmac-file-server-linux-arm       # Linux ARM 32-bit (Raspberry Pi 3)
# hmac-file-server-linux-arm64     # Linux ARM 64-bit (Raspberry Pi 4+)

# Use the appropriate one for your system
./builds/hmac-file-server-linux-amd64 -genconfig > config.toml
```

### Build More Architectures

```bash
# Interactive builder for all platforms
./build-multi-arch.sh

# Quick Docker multi-arch build
./docker-multiarch-build.sh --local
```

### Generate Configuration Templates
```bash
# Using local builds
./builds/hmac-file-server-linux-amd64 -genconfig > config.toml              # Basic config
./builds/hmac-file-server-linux-amd64 -genconfig-mobile > mobile.toml       # Mobile-optimized  
./builds/hmac-file-server-linux-amd64 -genconfig-enterprise > enterprise.toml # Enterprise config

# Or using downloaded binary
./hmac-file-server -genconfig > config.toml              # Basic config
./hmac-file-server -genconfig-mobile > mobile.toml       # Mobile-optimized  
./hmac-file-server -genconfig-enterprise > enterprise.toml # Enterprise config
```

### Validate Configuration
```bash
./hmac-file-server -config config.toml --validate        # Check configuration
./hmac-file-server -config config.toml --validate-quiet  # Silent validation
```

### Test Configuration
```bash
./hmac-file-server -config config.toml --check          # Dry run test
```

## 🌐 **Integration with XMPP**

### ejabberd Configuration
```yaml
# ejabberd.yml - Add to modules section
modules:
  mod_http_upload:
    put_url: "http://your-server:8080/upload"
    get_url: "http://your-server:8080/file"
    secret: "your-hmac-secret"
    max_size: 104857600  # 100MB
```

### Prosody Configuration  
```lua
-- prosody.cfg.lua
Component "upload.yourdomain.com" "http_upload"
    http_upload_url = "http://your-server:8080/upload"
    http_upload_file_size_limit = 100 * 1024 * 1024 -- 100MB
```

---

## 🔍 **Verify Installation**

### Check Server Status
```bash
# Test server is running
curl http://localhost:8080/health

# Check version (using local builds)
./builds/hmac-file-server-linux-amd64 -version

# Or using downloaded binary
./hmac-file-server -version

# View configuration
./hmac-file-server -config config.toml --validate
```

### Test Upload (with XMPP client)
1. **Configure your XMPP client** with the server URL
2. **Send a file** in any chat
3. **Verify upload** in the `uploads` directory

---

## 🆘 **Troubleshooting**

### Common Issues

**❌ Port already in use**
```bash
# Change port in config.toml
listenport = "8081"  # Use different port
```

**❌ Permission denied**
```bash
# Create uploads directory with proper permissions
mkdir -p uploads
chmod 755 uploads
```

**❌ XMPP upload fails**
```bash
# Use the XMPP client fixing tool
./fix_xmpp_clients.sh
```

**❌ Network switching issues**
```bash
# Test network resilience
./verify_network_resilience.sh
```
