+ * Any module harnessing Workflows module must define a Workflow Type Plugin.
+ * This allows the module to tailor the workflow to its specific need. For
+ * example, Content Moderation module uses its the Workflow Type Plugin to link
+ * workflows to entities. On their own, workflows are a stand-alone concept. It
+ * takes a module such as Content Moderation to give the workflow context.
