# Derivations

- [Child theme](https://themedocs.zenit.design/en/faq/derivations/child-theme.md): A child theme is installed as a plugin and serves as a template for the programmer. It is installed in the admin area in addition to the parent theme.
- [Theme duplicate](https://themedocs.zenit.design/en/faq/derivations/theme-duplicate.md): A theme duplicate is technically different from a child theme. It is a virtual copy of a theme in the database.
