How can I create a settings page for my custom plugin?

<!-- BEGIN COPY / PASTE -->
    add_action('admin_menu', 'my_plugin_create_menu');

    function my_plugin_create_menu() {
      add_menu_page(
        'My Plugin Settings', // Page title
        'My Plugin',          // Menu title
        'manage_options',     // Capability
        'my-plugin-settings', // Menu slug
        'my_plugin_settings_page' // Callback function
      );
    }

    function my_plugin_settings_page() {
      echo '<div class="wrap">';
      echo '<h1>My Plugin Settings</h1>';
      echo '<form method="post" action="options.php">';
      settings_fields('my_plugin_options_group');
      do_settings_sections('my-plugin-settings');
      submit_button();
      echo '</form>';
      echo '</div>';
    }
    <!-- END COPY / PASTE -->
