- 64-bit architecture (x86_64, ARM64)
- 4GB RAM minimum (8GB recommended)
- 1GB disk space

### Install Module Registry

```bash
# Add to Cargo.toml
[dependencies]
module-registry = "0.1.0"

# Or install via cargo
cargo add module-registry
```

### Verify Installation

```rust
use module_registry::{ModuleRegistry, ModuleConfig, ModuleType};

fn main() {
    let registry = ModuleRegistry::new();
    println!("Module Registry installed successfully!");
}
```

## Quick Start

### Basic Module Registration

```rust
use module_registry::{ModuleRegistry, ModuleConfig, ModuleType};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a new module registry
    let registry = ModuleRegistry::new();
    
    // Register a simple module
    let config = ModuleConfig::new()
        .with_name("data-processor")
        .with_version("1.0.0")
        .with_type(ModuleType::DataProcessor)
        .add_capability("processing");
    
    registry.register(config)?;
    
    // Check if module is registered
    if registry.is_registered("data-processor") {
        println!("✅ Module 'data-processor' is registered");
    }
    
    Ok(())
}
```

### Module Discovery

```rust
use module_registry::{ModuleRegistry, ModuleConfig, ModuleType, DiscoveryQuery};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let registry = ModuleRegistry::new();
    
    // Register multiple modules
    let modules = vec![
        ("data-processor", ModuleType::DataProcessor),
        ("data-analyzer", ModuleType::Analyzer),
        ("data-storage", ModuleType::Storage),
    ];
    
    for (name, module_type) in modules {
        let config = ModuleConfig::new()
            .with_name(name)
            .with_version("1.0.0")
            .with_type(module_type);
        
        registry.register(config)?;
    }
    
    // Discover modules by type
    let query = DiscoveryQuery::new()
        .with_type_filter(ModuleType::DataProcessor);
    
    let found_modules = registry.discover(query)?;
    println!("Found {} data processor modules", found_modules.len());
    
    Ok(())
}
```

### Module Instantiation

```rust
use module_registry::{ModuleRegistry, ModuleConfig, ModuleType};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let registry = ModuleRegistry::new();
    
    // Register a module
    let config = ModuleConfig::new()
        .with_name("data-processor")
        .with_version("1.0.0")
        .with_type(ModuleType::DataProcessor);
    
    registry.register(config)?;
    
    // Create a module instance
    let instance = registry.create("data-processor")?;
    
    // Use the module
    let data = b"Hello, World!";
    let result = instance.process(data)?;
    
    println!("Processed data: {:?}", result);
    
    Ok(())
}
```

## Basic Configuration
