How do I create a ruleset component?
While Rules components may successfully be created and used programmatically, as of Rules 8.x-3.0-alpha4 there is only minimal support for doing this in the UI. Adding these UI features is part of the last meta task needed to be completed before a beta version of Rules is released. You can discover the current status of these UI porting issues by reading the Rules issue queue at https://www.drupal.org/project/issues/rules
