Many YAML files in this directory's subdirectories, like [features](features), [glossaries](glossaries), [variables](variables), and [learning tracks](learning-tracks), as well as Markdown files within the [reusables](reusables) directory, can include YAML versioning or Liquid versioning within Markdown strings. See the README.md files in the subdirectories for details.
