Modules and themes can provide help topics as Twig-file-based plugins in a project sub-directory called <em>help_topics</em>; plugin metadata is provided in YAML front matter within each Twig file. Plugin-based help topics provided by modules and themes will automatically be updated when a module or theme is updated. Use the plugins in <em>core/modules/help/help_topics</em> as a guide when writing and formatting a help topic plugin for your theme or module.
