Why does 1s-bitrix not display the component in the list?

Question

1C-Bitrix

I'm making my first component from scratch. The problem is that it is not displayed in the list of components (when changing the page as HTML): it is not displayed either in the Content - Catalog - Product Documentation, or in the search by name.
File structure:
/local/components/module/catalog.documentagion/
-.description.php
-.parameters.php
-component.php
-lang/
--ru/
---.description.php
---.parameters.php
- templates/
--.default
---template.php
---etc.

.description.php:

<? 
$arComponentDescription = array(
   "NAME" => GetMessage("CAT_DOC_DESCR_NAME"),
   "DESCRIPTION" => GetMessage("CAT_DOC_DESCR_DESCR"),
   "PATH" => array(
    "ID" => "content",
    "CHILD" => array(
      "ID" => "catalog",
      "NAME" => GetMessage("CAT_DOC_DESCR_CATALOG"),
      "SORT" => 30,
      "CHILD" => array(
        "ID" => "catalog_cmpx",
      ),
    ),
  ),
);
?>

lang/en/.description.php:

<?
$MESS['CAT_DOC_DESCR_NAME'] = 'Документация товаров';
$MESS['CAT_DOC_DESCR_DESCR'] = 'Страница со списком документации всех товаров. Требует инфоблоков с соответствующей структурой: Документы, Типы документов.';
$MESS['CAT_DOC_DESCR_CATALOG'] = 'Каталог';
