The Catalyst series of themes and starters for GatsbyJS were designed to provide an opinoinated set of integrated themes and starters that can be used to accelerate your next Gatsby project. The vision is for one “core” theme in which most dependencies and components are contained followed by progressively more styled and refined child themes and starters. These themes rely heavily on Theme-UI and MDX.
