+## Instance specific features
+
+### IBM Watson chat
+The Päätöksenteko ja hallinto site features the IBM Watson Chatbot on few pages. You can configure the chatbot on the
+block layout page (admin/structure/block). More documentation about the chatbot is available in [Confluence](https://helsinkisolutionoffice.atlassian.net/wiki/spaces/HEL/pages/8145469986/IBM+Chat+App+Drupal+integration), and the
+code for the Drupal block can be found [here](https://github.com/City-of-Helsinki/drupal-helfi-platform-config/blob/main/src/Plugin/Block/IbmChatApp.php).
+
+### Menu depth override
+The maximum menu depth has been set to 6 (the default is 4). This change primarily affects the sidebar menu. The depth
+modification has been made in the [hdbt_subtheme.theme](https://github.com/City-of-Helsinki/drupal-helfi-strategia/blob/dev/public/themes/custom/hdbt_subtheme/hdbt_subtheme.theme) file.
+The menus support a deeper structure by default, so no additional changes, such as style adjustments, have been
+necessary.
+
+### Templates under the hdbt_subtheme
+The Päätöksenteko ja hallinto instance includes a few templates for the _Service List Search_ paragraph used on the
+site. These files are:
+- `form--views-exposed-form-service-list-block-search`
+- `input--textfield--service-list-search`
+Since the paragraph is globally available, it might be a good idea in the future to move these files to the hdbt theme.
