-## Code Quality Tools
+## Adding custom CSS
+When importing CSS from a third-party package for the first time, you may encounter the error `Module parse failed: Unexpected token... You may need an appropriate loader to handle this file typ...`. You need to register the path to the stylesheet directory in [stylePaths.js](./stylePaths.js). We specify these explicity for performance reasons to avoid webpack needing to crawl through the entire node_modules directory when parsing CSS modules.
