Warhol

Configuration

---

The pattern library configuration is how you connect Warhol to your pattern library. It lets Warhol know where to find your pattern library on the web, which breakpoints the pattern library implements, which selectors to use to identify components and so on.

You can set up the configuration for a pattern library in the pattern library screen in the web app.
