How can PHP beginners effectively use Composer for library management in their projects?

PHP beginners can effectively use Composer for library management in their projects by creating a `composer.json` file in the project directory and defining the required libraries in it. They can then run `composer install` in the terminal to install the specified libraries and autoload them in their PHP files using `require 'vendor/autoload.php';`. 

// composer.json
{
    "require": {
        "vendor/library": "^1.0"
    }
}
```

```php
// index.php
require 'vendor/autoload.php';

// Start using the library
