 *
 * Through hook_help(), a module can make documentation available to the user
 * for the module as a whole or for specific routes. Where the help appears
 * depends on the $route_name specified.
 *
 * Help text will be displayed in the region designated for help text. Typically
 * this is the 'Help' region which can be found at admin/structure/block.
 *
 * The help text in the first example below, will appear on the simple page at
 * examples/page-example/simple.
 *
 * The second example text will be available on the admin help page (admin/help)
 * in the list of help topics using the name of the module. To specify help in
 * the admin section combine the special route name of 'help.page' with the
 * module's machine name, as in 'help.page.page_example' below.
 *
 * See the Help text standard page for the proposed format of help texts.
 *
 * @see https://www.drupal.org/documentation/help-text-standards
