WordPress "wp_register_style was called incorrectly"?

Question

I've google'd all over the place for an answer, but can't find any decent answers with an actual solution. So, I'll firstly explain my issue.

I'm using a custom theme that I've made, in the latest version of WordPress.

I wanted to do the proper thing, and not hardcode my styles and scripts into the header.php file, but enqueue them using WordPress functions.

Here are the notices shown when debugging is enabled:

Here's the relevant part in my functions.php file:

/**
 * Register global styles & scripts.
 */
wp_register_style('my-fonts', '//fonts.googleapis.com/css?family=Lato:300,400,700,900');
wp_register_style('fontawesome', '//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css');
wp_register_style('my-styles', get_template_directory_uri() . '/assets/css/main.css');

wp_register_script('bootstrap', 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js', array( 'jquery' ));
wp_register_script('scripts', get_template_directory_uri() . '/assets/js/scripts.js', array( 'jquery' ));


/**
 * Enqueue global styles & scripts.
 */

wp_enqueue_style('my-styles');
wp_enqueue_style('my-fonts');
wp_enqueue_style('fontawesome');

wp_enqueue_script('bootstrap');
wp_enqueue_script('scripts');

I'm guessing from the debugging notices that I need to somehow specify to load WordPress's 'wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks'

Well, I found out what I'd done wrong! Here's what I did for anyone interested:

I changed this:

/**
 * Register global styles & scripts.
 */
wp_register_style('my-fonts', '//fonts.googleapis.com/css?family=Lato:300,400,700,900');
wp_register_style('fontawesome', '//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css');
wp_register_style('my-styles', get_template_directory_uri() . '/assets/css/main.css');

wp_register_script('bootstrap', 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js', array( 'jquery' ));
wp_register_script('scripts', get_template_directory_uri() . '/assets/js/scripts.js', array( 'jquery' ));


/**
 * Enqueue global styles & scripts.
 */

wp_enqueue_style('my-styles');
wp_enqueue_style('my-fonts');
wp_enqueue_style('fontawesome');

wp_enqueue_script('bootstrap');
wp_enqueue_script('scripts');

To this:

function my_scripts() {
/**
 * Register global styles & scripts.
 */
wp_register_style('my-fonts', '//fonts.googleapis.com/css?family=Lato:300,400,700,900');
wp_register_style('fontawesome', '//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css');
wp_register_style('my-styles', get_template_directory_uri() . '/assets/css/main.css');

wp_register_script('bootstrap', 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js', array( 'jquery' ));
wp_register_script('scripts', get_template_directory_uri() . '/assets/js/scripts.js', array( 'jquery' ));


/**
 * Enqueue global styles & scripts.
 */

wp_enqueue_style('my-styles');
wp_enqueue_style('my-fonts');
wp_enqueue_style('fontawesome');

wp_enqueue_script('bootstrap');
wp_enqueue_script('scripts');
}

And added this:

add_action( 'wp_enqueue_scripts', 'my_scripts' );
