- * Provides the default help_topic manager.

- * Modules and themes can provide help topics in .html.twig files called

- * help_topics. The provider is validated to be the extension that provides the
- * help topic.
- *
- * The Twig file must contain YAML front matter with a key named 'label'. It can
- * also contain keys named 'top_level' and 'related'. For example:
- * @code
- * ---
- * label: 'Configuring error responses, including 403/404 pages'
- *
- * # Related help topics in an array.
- * related:
- *   - core.config_basic
- *   - core.maintenance
- *
- * # If the value is true then the help topic will appear on admin/help.
- * top_level: true
- * ---
- * @endcode
- *
- * In addition, modules wishing to add plugins can define them in a
- * module_name.help_topics.yml file, with the plugin ID as the heading for
- * each entry, and these properties:
- * - id: The plugin ID.
- * - class: The name of your plugin class, implementing

- * - top_level: TRUE if the topic is top-level.
- * - related: Array of IDs of topics this one is related to.
- * - Additional properties that your plugin class needs, such as 'label'.
- *
- * You can also provide an entry that designates a plugin deriver class in your
- * help_topics.yml file, with a heading giving a prefix ID for your group of
- * derived plugins, and a 'deriver' property giving the name of a class
- * implementing \Drupal\Component\Plugin\Derivative\DeriverInterface. Example:
- * @code
