 - **Project**: an implementation of an Emulsify starter, such as [emulsify-drupal](https://github.com/emulsify-ds/emulsify-drupal).
-- **System**: a design system that defines components, and assets. Emulsify projects opt into using systems using cli commands. Once a system has been selected for a project, the system will mandate how components are organized, install required components/assets, and give developers the ability to find and install non-required components.
-- **Variant**: systems may have as many variants as they want. For example, a system might have a Drupal variant, a WordPress variant, and a React variant. The system is the same (imagine Material-UI is a system), but each variant may define different types of components, or have different organization patterns that are compatible with different platforms.
